Durango, Colorado 7:16 Mountain Standard Time
Aurora: A red layer of light with some vertical streaks above a green layer. Stars are visible behind the red, and a few horizontal clouds lie across the green layer. Phone photo with 3 second exposure, taken looking north.

Around 3:30 pm, when the Animas was flowing at around 2200 cfs, the kayakers were out enjoying the whitewater park.
Nine brightly colored kayaks take turns playing in a rapid. Brown water flows past a barrier of grey, tan, and white rocks, which constrict the flow.

Went up high yesterday to sample water near Red Mountain Pass for the Mountain Studies Institute. (Their volunteer E. coli monitoring program, not acidity or metals.)
Photo of Red Mountain Pass, Colorado. The mountains behind US highway 550 have bare slopes of orange mineralized rock and fresher grey rock. The very top of the tallest mountain is dusted with snow. Puffy white cumulus clouds stretch across a bright blue sky.

They looked cooler when they were wet.
Photo of a green jewelry box, opened to show lots of nondescript grey pebbles. Most are metamorphic rocks, with a few granites and vein quartz.

Guess what was in this old jewelry box (which I've had since childhood)?
Photo of a dark green jewelry box inside a cardboard box. The latch is closed, and made of cheap (but gold-colored) metal.

Post pictures of when your pets were little.
Photo of an orange tabby kitten lying behind a larger grey tabby kitten. The orange kitten's paws are on the grey kitten's back, and the orange kitten's face is tucked into the grey kitten's neck.

Albuquerque (because I'm closer to that than to Denver, and topography and microclimates mean that neither exactly represents me).

Note that the areas on the thumbnails are further in the past, and have more blue (cool) than today.
Visualization of the annual temperature of Albuquerque, New Mexico, starting with blue (colder) bars on the left and ending today with red (hotter) bars on the right.

Field trip sites on public land, for sale in the reconciliation bill: 2) Molas Pass.
Map showing Forest Service (green) and BLM (orange) land that would be available for sale according to the Wilderness Society map. The area between Silverton and Snowdon Peak includes the Little Molas Lake campground and the Andrews Lake recreation area. Photo of a group of students from behind, sketching an unconformity visible from Molas Pass.

Field trip sites that would be for sale in the reconciliation bill. 1) Haviland Lake and Chris Park campground and trail network.
Map from The Wilderness Society showing a large area in green that represents Forest Service land that could be sold under the Senate reconciliation bill. It stretches from US highway 550 to the Animas River and includes a large area east and south of Haviland Lake. Photo looking down at an outcrop surface, showing a white intrusion into dark grey amphibolitic gneiss. The intrusion looks like a moose head. Photo of the view west from the Haviland Lake campground across the lake to the cliffs south of Purgatory Resort. Both the cliffs and the lake shore are on the map of land for sale. Photo looking down on an outcrop of grey gneiss cut by squiggly foldes quartz veins.

Umm, you're psychic?
Screenshot of a Bluesky timeline. Zzyzx posts: "Tour announcement any second now!" Phish posts: "Before summer comes to a close, Phish will head south from Louisville in September for two shows each in Birmingham, AL and Alpharetta, GA. The following weekend finds the band settling in for three nights at Hampton Colisesum. Request tickets now. Details below." Both posts were made 1 minute before the screenshot.

This is near Goblin Valley State Park. The thin slabs that are stronger than the rest of the rock are deformation bands or small faults. Lots of them have slickenlines on their surfaces.
Several layers of sandstone stick out of a desert hillside. In the middle of the photo, a thin slab of rock sticks out of the top of a layer, sloping about 45 degrees into the hill. At the top of the hill, a pair of thin slabs slope towards each other, making a truncated V shape with puffy white clouds behind it.

This is hilarious and deserves alt text!
A geode with googly-eyed reddish and tan layers looks at the camera with its mouth open and corners turned down. It looks a bit like a fossil of Gritty, the wild-eyed orange mascot of the Philadelphia Flyers.

I love the cool-looking sticker trend. Here's mine:
The words "I voted" with a blue columbine replacing the "o", over cliffs of red rock and desert vegetation.

My "I voted" sticker is as awesome as ballots by mail with convenient drop boxes.
The words "I voted" with a blue columbine in place of the "o" above a drawing of a red-rock canyon and flowering cacti and other dry-country plants.

Honestly I'm just happy that the lovely pressure-indicating metamorphic mineral made it to the finals. (Sedimentary and igneous rocks are so much more accessible, but I love those weird squishy deep rocks.)
Large blue striated crystals of kyanite, in a jumbled mess with tan crystals. A labeled black-and-white photo of a thin section containing a large squarish crystal of andalusite (And), partly replaces by high-relief blades of kyanite (Ky). Fuzzy grey mats of sillimanite (Sil), low-relief muscovite (M), a small truncated-diamond crystal of staurolite (St), and a half-crystal of garnet (Gt) are also labeled.

I saw it!
A pink streak stretched across a dark sky. Trees are silhouetted in the foreground. A pink glow covers part of the sky behind a large house.

Copper minerals, slickenlines, NAGT pencil...
A bright blue and brown rock with many parallel scratch-like lines, beside a yellow mechanical pencil. According to the scale on the pencil, the rock is about 10 cm long.

⛏️ A 3D model of the topography of the Animas Valley at the Peter Carver Memorial Overlook in Durango, Colorado, on the Rim Trail near Fort Lewis College.
A slivery metallic sculpture of a landscape beside a shaded relief map. In the background a pair of flat-topped mountains show layers of rocks on the cliffs that drop into the valley between them.

Search drinks in your camera roll: I got the make-a-fracture-in-gelatin experiment. And Glen Canyon Dam.
A plastic gatorade bottle filled with clear gelatin and a straw. A high concrete dam with dark blue water behind it, durrounded by a desert of red and tan sandstone.
