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.

West Blue Mound, highest point in southern Wisconsin, on the horizon from a ridgetop in Lafayette County, Wisconsin. East Blue Mound is also visible at the right edge of the photo.

View from a high point across dissected terrain with lots of trees toward amostly flat horizon withe a high summit rising above it just to the right of center of the photo. A two lane road drops down a hill in the foreground, rising to another summit in the middle ground. Another somewhat lower distinct summit is at the right edge of the photo.

Friday ice update - #Arctic sea ice extent is currently the 10th lowest on record (JAXA data)

• about 50,000 km² above the 2010s mean
• about 1,040,000 km² below the 2000s mean
• about 2,020,000 km² below the 1990s mean
• about 2,760,000 km² below the 1980s mean

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between July and October by looking at the decadal average line positions.

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.

A map of soil color at 125 cm, across the Midwest. There are reddish brown colors around Lake Superior and south and west from there for some distance into Minnesota and Wisconsin. Yellowish-greenish-gray colors predominate in the southwest and there are some bright white to orange colors in part of western Wisconsin, 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...

Left: A map of the drainage network of Blockhouse Creek near Platteville, Wisconsin, hand-drawn by my Ph.D. advisor Jim Knox, I believe for his PhD research ca. 1967. Right, drainage network for the same basin, NHDPlus data. Pretty different definitions of "1st order" streams.

A hand drawn map of a dense stream network with many fine branches.

The same stream network as the other image, this time mapped from the National Hydrography Dataset Plus, with only a few larger channels shown as blue lines.

Federal data show thousands of Forest Service wildland firefighter jobs are vacant, a figure a top House Democrat cited in a letter demanding the Trump administration account for staffing cuts that have hampered the agency's ability to fight fires.

Top Democrat on Oversight Committee Demands Trump Administration Account for Wildland Firefighter Vacancies

The request follows ProPublica reporting that DOGE cuts and voluntary resignations left thousands of vacant jobs at the Forest Service, severely hampering its ability to fight wildfires.
