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.
