Late October Event

 - Saturday, October 31              9:00am-noon
 -  Jordan MN Town Hall, 18380 Cty Hwy 102, Chatfield MN
In partnership with the Lost Creek Hiking Trail/Bluff Country Hiking Club, we're hosting a free Halloween hike. The event will feature a self-guided fall hike beginning at Jordan Town Hall. Hikers will travel to the western terminus of the trail and hike 1.5 miles to the Bailey Loop, followed by an optional hike - a mile loop - to complete a total of four miles of hiking by the time they return to the trailhead. In the spirit of Halloween, participants can expect to encounter skeletons and other Halloween-themed surprises along the route. A selection of grab-and-go breakfast foods and drinks will be available for participants to enjoy before or after their hike. The celebration is particularly intended as an opportunity to recognize and thank the landowners who have made the Lost Creek Hiking Trail possible over the past 15 years. Their willingness to provide trail access has played an important role in creating a recreational resource for residents and visitors to the area. The Lost Creek Hiking Trail is connected to the ongoing development of the Minnesota Driftless Hiking Trail (MDHT), a planned long-distance hiking trail through southeastern Minnesota. MDHT is working with landowners, communities, and public land managers to build a sustainable trail that connects people, communities, and landscapes throughout the Driftless Region. The event is free and open to the public. Participants are welcome to stop by anytime between 9 a.m. and noon to hike and enjoy the refreshments.For more information about the Lost Creek Hiking Trail, visit bluffcountryhikingclub.org.

 - Saturday and Sunday, November 7-8        10:00am-2:00pm
Brownsville Overlook, Hwy 26 , MN
Come enjoy the fall migration at the Upper Mississippi River National Wildlife and Fish Refuge! Listen to the clamorous chorus of tundra swans, ducks, and geese, and the calls of bald eagles above. See the river come to life as birds take off and land at one of the best rest stops for people and wildlife on the Mississippi Flyway! A Refuge naturalist will be available at the Brownsville Overlook from 10:00 a.m. to 2:00 p.m. on Saturdays and Sundays, beginning Sat. November 7 through Sun. November 22, 2026, weather permitting. They'll have a spotting scope and bird guides to help you identify what you see. It's FREE to come visit! The Brownsville Overlook is one of the top places along the river to see this fall show. This roadside pull off is located about 3 miles south of Brownsville, Minn. along MN-HWY 26. Please dress for chilly weather - it is always a little breezy by the water. The naturalist will also be part of a special event on Sat. Nov 14, called “Waterfowl Observation Day.” More details about Waterfowl Observation Day can be on our events page here: https://www.fws.gov/refuge/upper-mississippi-river/events Peak migration can be hard to predict. The best time to see the tundra swans is usually mid-to-late November. Many kinds of birds stop here and each day brings something new! Recent bird sightings are updated once per week on our website - https://www.fws.gov/refuge/upper-mississippi-river. For the real bird nerds (our kind of company) - the timing of when the swans arrive depends partly on temperatures in their northern breeding grounds in Canada and Alaska - as bodies of water begin to freeze there, the swans gradually migrate to the Mississippi River. The swans will usually stay here for about one month or until the river freezes. If the weather is warm here, the swans may not spend as much time close to the overlook. As the water on the Mississippi River freezes, it pushes them to group up in areas where they can best find food and shelter. Even if they're not super close to the overlook, the sound of their calls and the sight of large groups of birds is still a celebration to experience! For more information, please call the La Crosse District Visitor Center at 608-779-2399. The Visitor Center address is N5727 County Road Z, Onalaska, WI 54650.

Tree ID - Second Saturday Hike 
 - Saturday, November 14           9:00am to around 12:00pm
 - Lower Hixon Trailhead (2600 Old Quarry Rd La Crosse WI
For now the trees still hold leaves but soon they'll shed them and we all might feel a bit lost without those helpful little bundles of light-eating chlorophyll that are so often distinct in many of our common trees. Fear not! Join us for an autumn hike through the Blufflands while learning how to identify trees without their leaves! This hike will offer an opportunity for folks to learn some helpful tips and tricks to identify common local tree species by their bark, branches, twigs, and overall growth form! We'll also learn a bit about forest management and the variety of other flora and fauna that thrive in our Bluffland woodlands.  This event will be led by Greg Edge, a retired Wisconsin DNR Ecologist and Silviculturist and co-host of SilviCast, a popular podcast "devoted to silviculture: the science, practice, and art of forestry." Brody Waldenberger, a forestry student at the University of Minnesota and former WisCorps Individual Placement with Friends of the Blufflands and Mississippi Valley Conservancy this past summer, will also help to lead this hike, sharing his expertise on the management and restoration of our woodlands. Difficulty: This will be a moderate hike up the Miller Bluff trail from the Lower Hixon Trailhead. Depending on interest and time, we may hike all the way up to Stry Prairie, about a 2-mile round trip with 500 ft of elevation gain. Wear sturdy hiking shoes and bring water and a snack if needed. As always, if this needs to be canceled due to rain, an email will be sent out and it will be posted on the Friends of the Blufflands Facebook page. Sponsor: Friends of the Blufflands

 - Saturday, November 14        10:00 am- 2:00pm
 - Brownsville Overlook, Hwy 26, MN; Shady Maple Overlook, Stoddard WI
Join us for Waterfowl Observation Day on Saturday, November 14, from 10:00 a.m. to 2:00 p.m. at two roadside overlooks in the La Crosse District of the Upper Mississippi River National Wildlife and Fish Refuge (Refuge). Listen to the lively calls of tundra swans, watch bald eagles soar overhead, and see how many species of ducks and other waterbirds you can identify. The Upper Mississippi River National Wildlife and Fish Refuge is a critical stopover site for tundra swans; there are few other places you can enjoy such a phenomenal fall show! This FREE event is open to all ages. Nonprofit partners will be present at the Brownsville and Shady Maple Overlooks during this special event to help visitors identify birds and learn more about migration. The Brownsville Overlook is located about three miles south of Brownsville, Minn., along Minnesota State Highway 26. The Shady Maple Overlook is located on the Wisconsin side of the river, about three miles south of La Crosse, Wisc. along Wisconsin Highway 35. Stop by one or both roadside pull-offs to enjoy the fall migration and learn from local experts! Light refreshments will be offered during Waterfowl Observation Day at the Brownsville Overlook, while supplies last, courtesy of the Friends of the Upper Mississippi River (FUM). Nonprofit partners will also have nature-themed items available for purchase at this location. A portable toilet will be onsite, provided by Kids and Mentors Outdoors (KAMO). Volunteers from the Friends of the Refuge – Mississippi River Pools 7 & 8 (FOR78), FUM, and KAMO will provide interpretation at the Brownsville Overlook, while members of the Izaak Walton League – Upper Mississippi River Chapter will provide interpretation at the Shady Maple Overlook. We are very grateful to our partners for helping bring Waterfowl Observation Day to life! Parking at both overlooks is limited. If parking lots are full when you arrive, please consider visiting another site and returning later. The Highway 26 Overlook, located about ½ mile south of the Brownsville Overlook, is usually a great place to see rafts of diving ducks.

Sunday, November 22 - Registration opens for Saturday, December 26 Owl Prowl 
 - International Owl Center, 126 E Cedar St., Houston, MN
We start with a 30-45 minute program indoors to teach you how to identify owls by sound and the ethics of calling owls. Then you hop in your vehicle and follow the Owlmobile to about three different locations in rural Houston where Jo, our resident expert owl caller, will imitate owl calls in hopes of getting some responses. The program is capped at 30 participants, and these always sell out in advance. Cost is $10 for members and $15 for non-members. Due to the need to stand perfectly still for 10 minutes or more at a time, these owl prowls are not recommended for children under age 12. No pets, smoking or vaping allowed either indoors or outdoors. For more detailed information, click here. Sponsor: International Owl Center

Minnesota state parks are open year-round, and there's a state park within 30 miles of most Minnesotans. With a free day in each season, it's a great opportunity to get out there and explore someplace new - or visit an old favorite at a new time of year! Whether you stay for the whole weekend or just spend a few hours outside, you'll make memories that will last a lifetime. The entrance fee waiver for fee-free days does not cover amenity or user fees for activities like camping, rentals, or special tours. The goal is to encourage families and friends to spend time together in nature. Research shows many health and wellness benefits to spending time in nature. According to ParkRx, contact with nature improves one’s physical, mental, and spiritual health. Getting outdoors makes exercise more fun and can boost mood and immunity. The American Psychological Association shares that exposure to nature is linked to benefits including improved attention, lower stress, reduced risk of psychiatric disorders and even increases in empathy and cooperation. Sponsor: MN DNR

Naturalist's Corner - Slipping into Senescence

It's always a pleasure to welcome back Linda Haugen of Iowisota, a nature-themed retreat and education center located in the Driftless Area of Northeast Iowa. Linda and her husband Dennis have created a marvelous learning center along the Mississippi River. They offer programs and retreat space year round centered on the nature and arts that surround them. In her blog, Linda often reflects deeply on some aspect of nature, bringing her curiosity, expertise in science and US Forest Service background to the forefront as she writes the Iowisota blog. Her latest post is a deep dive into the natural cycle of living oraganisms' lives as fall descends. The following blog post is reprinted with permission from the September 22, 2026 Iowasota blog

Senescence
By Linda Haugen, Iowisota blog 

Senescence seemed an appropriate topic to delve into as the leaves begin to change color, so I dug out my old plant physiology text to refresh my memory. I was reminded that senescence is “the processes that accompany aging and that lead to death of an organ or organism”. I was also reminded that college textbooks have a magic ability to induce drowsiness! Although the science is still valid, my textbook is from 1985, so the probability of inducing a nap correlates with “the processes that accompany aging” in my own body! I’ll try to lighten up this discussion of PLANT senescence enough to keep you awake!


In herbaceous annual plants and grasses (like flowers and crops), senescence begins when the plants flower and continues as the plant redirects its energy to the production of seeds. Eventually the leaves die, and the seeds are left to restart the cycle next year. Perennial plants are similar, with energy being redirected to roots, tubers, and other storage organs that will overwinter.  Trees are a bit different, since the whole plant does not die every year. But the leaves die, and the sugars and nutrients that were previously in the leaves are conserved over the winter in the twig, stem and root tissues of the tree. Plant growth regulators (like cytokinin, gibberellins, and auxins) are chemicals that signal the plant to keep energy in the leaves for growth or redirect it to other plant parts.


In trees, when the leaves start to senesce, they often change color. Sometimes from green to strikingly beautiful colors. Most of the colors are due to the balance of chlorophyll (green), carotenoids (yellow, orange and brown), and anthocyanins (red). The chemicals, and thus the colors, are there all through the season; as the chlorophyll is broken down, the other colors show up. Different tree species have signature patterns of color change, including timing and color. The sumac shrub is always one of the first brilliant changes that we see in northeast Iowa, with thickets of sumac forming bright red patches of vegetation before they fall off. Right now, I am seeing some yellows in the leaves of the walnuts and basswood. We have not yet had a frost, so the triggers for this are probably day length and leaf diseases.  As the season progresses, we will see bright golden, orange, and red patches of maples. The reds, browns and russets we will see on the hillsides later in the season are often the oaks. Iowa DNR maintains a Fall Color Report with updates of the development of color across the State (starting September 30) and information on the common colors of different tree species. Wisconsin and Minnesota DNRs also have fall color pages.



Earlier in the summer, I’ve shared pictures of the verdant green colonies of lotus in the backwaters of the Mississippi River. The lotus is done blooming now, and the energy from all of that chlorophyll-filled photosynthesis has been packed into the seedheads and tubers. The leaves are senescing and fading away.

Nature School - A Feast of Ferns

Longtime readers know that I am a huge fan of guided hikes. We have a wealth of naturalists, nature lovers, birders, prairie enthusiasts, astronomers, botanists, mycologists, geologists, biologists, rangers, scientists and dedicated amateur outdoor users and observers in the Driftless. The opportunities to head out on the trails on a sponsored hike along with a subject expert or two is irresistible and on offer throughout the region and all during the the year. It seems a shame not to take advantage of the "nature school" hikes and programs they lead!

My most recent guided hike was sponsored by The Friends of the Blufflands.

Part of their "Second Saturday" series, Jon Rigden and Max Sorenson guided a fascinating September hike on Hixon Forest's Oak Trail. Our goal was taking a deep dive into learning about the ferns that we would encounter along the trail. Ferns have been a challenege for me so I was especially interested to add to my knowledge.

We started out looking through a microscope at sori (or spores) that are a way to help distinguish each type of fern. Max, a talented artist as well as naturalist, went over a sheet he made describing the parts of a fern and how each part helps in identifying what fern you are looking at. Just sorting out the correct names for the parts of a fern was great learning for me.





Interrupted fern sori
Ferns are fascinating old life forms - emerging almost 200 million years ago as "giants of the forest". They survived ensuing millenial as they were relegated to the understory where light is dim. They reproduce through sori as well rhizomes.


We also had the opportunity to look over some recommended field guides that Jon had brought along. Some were small enough to pop into a backpack on the trail like Joe Walewski's highly recommended, detailed but accessible guide Ferns and Allies of the North Woods;  Anne and Barbara Hallowell's abbreviated Fern Finder or Lynn Levine's Identifying Ferns the Easy Way; A Common Guide to Ferns of the Northeast. 

With these aids and resources examined, we were ready to start doing some serious field identification of ferns and other fascinating plants along the trail.  

While there are over 60 different fern species in the Driftless, we concentrated on the six species that we would observe on this hike. Recognizing the sori shapes and colors (whether on stalks or the underside of the pinna), the arrangement of the pinna (leaflets) and the blade shapes made identification much easier


Maidenhair
Sometimes confused with braken, which also has a tall stipe (stalk),  its spiraling blade is a sure identifying sign. It's name derives not from this spiral but from its thin black stalks. It is said to remind people of women's hair. Indigenous people used these strong stipes to weave baskets.




Spinulose Wood Fern
These ferns can be a bit tricky to identify. They have smaller pinna (leaflets) on the bottom two leaf pairs. Looking closely at the sori on the pinna's underside reveals light brown, triangle-shaped spores. Each pinna also has a tiny spine at its tip (hence spinulose). That will be the important identifying characteristic for me!





Lady Fern
This delicate and prolific fern's blade is diamond shaped - flaring out from the tip of the blade before once more narrowing at the bottom. The stipe has black "hair" and the sori have a hooked tip which is easily disguished.











Bulblet Fern
They have a very long axis (the stalk within the blade) with somewhat even-in length pinna down the stalk. Turning over a pinna reveals small green bulbs on the underside, which explain their name. In spring, their stipes are red. I have noted many of these on hikes especially in damp woods.

Interruped Fern
This large species is one of the most ancient ferns.Their sori appear in bunches partway down on the stalk, looking like brown, spent leaves. 




Sensitive Fern
Named for its extreme sensitivity to cold, this fern with its blocky pinnules, makes it one of the easiest to identify. Their sori are on stalks and they throw their spores when ready in a process called "explosive dehiscence". The action is similar to that of the jewelweed or touch-me-not, whose seeds launch out at a touch when the pod is ripe. Explosive dehiscence is my new favorite nature phrase!

The Friends of the Blufflands plan to hold two more "Second Saturday" hikes - one in October and one in November. Check their Facebook page or blog near the dates for details on these free guided hikes with great subject information and experts.




Nature School is what I like to call the guided hikes I go on when I’ve a mind to learn more about the natural world and to fulfill my required training hours to maintain my annual Master Naturalist volunteer certification. The Nature School series highlights parks, organizations and groups that provide free or low-cost guided learning experiences while hiking. The Driftless area of MN, WI and IA is rich in dedicated subject experts who share their knowledge, passion and expertise. By doing so, they help hikers of all ages better understand our natural world. It’s always a delight to attend their “schools.”

Nature Sneak Peek - October 2026

October really marks the end of most of our wild plant growth and the transitory migration period of much of our summer birds. We use different eyes on the trails this month. Eyes that look to the treetops and skies and eyes that scour the ground and trees to spot elusive fungi. 

What will we see on the trails this month?


Trees
Fall Leaf Color
Tamaracks

The leaves in the Driftless will spend most of the month finishing their life cycle. The stem end is sealing and getting ready to loose the leaves from the trees and bushes. And of course before that happens, spectacular color is in store followed by the more muted umbers of later fall. By Halloween, save for oaks and a few other late tree species, most leaves of deciduous trees will be down.

Tamarack Gold
These trees are a deciduous conifer. In mid- to late October, the needles of these woods and wetlands trees turn a golden yellow. Then they shed their needles 

Plants
October is the swan song for the very last flowering plants. Mostly we see seedheads with their feathery tops ready for October and November to blow their seeds far and wide. You will still see a few blooming flowers but once frost hits, blooms and insects alike are tough to find.

Asters 
These forbs still linger. These small-petaled beauties have a surprising large family of white, pink, blue and purple forms. They are especially prominent on woods walks and lend a bright pop of color alongside fading ferns.

Gentians
A few gentian species may hang on as well. If you are lucky, you may spot bottle gentian, stiff gentian or yellow gentian tucked away near sunnier wetlands and wild prairies.

Grasses
The towering grasses, in full seed, dominate prairies.

Hardy Bloomers
Keep an eye out for very late-blooming coneflower species, brown-eyed Susan, evening primrose, yarrow, and goldenrods. These bloomers are often smaller and tucked in among taller grasses and plants.


Birds
Migratory Songbirds
Songbirds have been heading to their wintering grounds since late August. The woods and filelds have quieted with only the sounds of bluejays, woodpeckers, owls and other over-wintering birds to pierce the soundscape. With leaves off the trees it is easier to spot sparrows in their late migration passing through. Watch Cornell University's Birdcast for forecasts of large nightly migrations like we had overnight on Thursday, October 1. Sunday's night's forecast is predicted to be huge for bird migration in the Driftless again. Be sure to turn off your lights at night to help these migrators.


Migratory Waterfowl
The diving ducks join the dabblers in migration. Geese and swans (trumpeters and tundras) are more numerous. Their migration is far from done but you will spot these water birds more often in open water, ponds and sloughs.

Grouse
Listen for the drumming of grouse on woods walks. Older males often drum when this year's now-grown chicks enter their territory.

Insects
Autumn meadowhawk - 
Note the reddish color




Crickets and Grasshoppers 
These hardy insects continue their busy lives and are, until frost, a sound most often heard on the prairie.

Autumn Meadowhawk Dragonflies
These are some of the last dragonflies active in the fall season. Their distinct red abdomen make them easy to spot. Watch for any sunny spot in wetlands and near water this month and you will see them warming before they continue their hunting activity.




Fungi
Wood ear fungi

Keep your eyes on trailsides, stumps, deadwood - and grass! Fall is a most excellent time to spot mushrooms, ghost pipe, and fungi of every kind and description. From edible maitake mushroom to dog nose fungus to lobster mushroom to wood ear and coral fungi to fairy fingers to dryads saddle to crowded parchment mushroom, there is a fungus or non-plant feast in the woods each fall.







No matter where you go this month, be curious. Take some extra time to look and see what you can see along the trail. You’ll be delighted!

I Spy On the Trails - September 2026

September full moonrise
Badlands National Park

If it’s September, I must be traveling! 

I spent time with my longtime paddling buddies in Upper Michigan’s Sylvania Wilderness during the first part of the month. This small canoe wilderness near and in the Ottawa National Forest has old growth forest, hiking trails and quiet enough to paddle, hike and relax in. 

After a week back home to gather my wits and repack, I was off with these same friends on a road trip to meet up with three of our Colorado Slickrocker hiking group gang for Badlands National Park exploring. Lots of laughs, good conversations and trail time.


Based on the above, I can’t say much about September’s Driftless climate other than what I’ve read! Suffice it to say, we had moderate and slightly warmer temperatures, some real gullywasher rain and a pleasant Autumn Equinox. Frost wasn’t yet in the picture.

Ghost pipes everywhere

We are well into the slowdown and final seed production of plants and forbs. Mushrooms are heavily evident in Driftless areas that have received rainfall this past month. Ghost pipes are in their glory. Asters and tall grasses are also at their peak.

Songbird migration has been heavy this month, often increasing ahead of dropping cold fronts. The first swans are just starting to appear along the Mississippi Flyway. Canada geese continue their flights as well. Observant eyes have spotted migrating egrets, cranes and herons in the area. Monarch butterflies are also  migrating through. Migrations of birds and insects will continue through fall.

I hope you enjoyed this mild September on the trails and are looking forward to the colorful time ahead.

The "I Spy on the Trails" column is a phenology (the study of seasonal changes in plants and animals) journal to chronicle the weather, plant life and wildlife I observe while hiking year-round. It is very useful in helping me compare observations from year-to-year. The column is published monthly from September through April and then twice-a-month from May through August when warm weather brings the natural world back to vibrant life.
