Cornus alternifolia (pagoda dogwood) is easier to spot at this time in the fall and it surprises me again how much of it there is unobtrusively growing under the oaks here.

CORN-ADO CHASING! It was another hot, sunny day with record heat in the Midwest, ripe for dust devils. During the harvest season when cornbelt dust devils fill with corn stalks, I call them corn-adoes! Got my drone into a few of them today.

The impact extreme rainfall events can have in a year - check out Tescott, KS. They'd probably be running near average year-to-date, but a pair of 6"+ rain events Jul 22 and Sep 9 have them running a 10"+ surplus.

Something good: a new, nonprofit newsroom run by some wonderful, experienced folks (core crew from Outside mag's glory days) dedicated to journalism about American public lands! Looks like the plan is to collaborate a fair bit with other outlets.

Glacier du Pays Bâché (Neouvielle, Pyrénées) ✝️
1896 | 2023

This glacier east of Pic Long (3192 m) disappeared more than 15 years ago! 📈

Was 900 m-long and 30+ ha during the LIA! 🧊💪

Only witnesses: a magnificent moraine and a glacial lake!

Who's next? 🔥

I'm concerned about a potential uptick in fire activity across western Canada in late August and early September - risk has been trending up with dryness over the last week, upcoming week of hot + dry conditions will put pressure on early September rainfall opportunities.

We saw this plume of smoke from a fire in the Wind River Mtns/Green River Lakes area today. It was reported this afternoon and within just a few hours was estimated at 600 acres. Insane. #wildfire

I'm thrilled to see this paper out, which I co-led with @ditchontologist.bsky.social, and featuring input from loads of excellent co-authors. It's our interdisciplinary perspective on ditches; what they do, why they matter, and how we should look after them.

Soil color at the scale of the Midwest. Two patterns depending on depth: 1. At 125 cm, it's about parent material. Greenish-gray Des Moines Lobe till to the west/southwest, and reddish-brown sediment of the Superior Lobe and others to the northeast. Sandstone colors in the northern Driftless Area.

One of the most spectacular lightning displays I've seen in my backyard in many years. I felt like I was fumbling my way through shooting most of the show & was just hoping I'd capture one image that conveyed how insane the show felt.

Every paragraph in this story about smoke exposure is brutal. I'm starting to question how wildland firefighting is any different from Russian soldiers clearing debris at Chernobyl--except it's in much slower motion & we all keep doing things to make it worse. 1/ www.nytimes.com/2025/08/17/u...
