Plate Flip xkcd.com/3258/
4-panel comic. (1) PERSON 1 with ponytail: These tectonic plates look pretty eroded. When did you last flip them? PERSON 2: Flip them? (2) PERSON 1: Yeah, to use the underside of the continent. PERSON 2: ...Never? PERSON 1: Wow. Explains the eons of weathering, debris basins, and... is this isostatic depression? PERSON 2: It’s rebounding! (3) PERSON 1: You really should flip it. You’ll get a whole new landscape! PERSON 2: But I like *this* landscape! (4) PERSON 1: Just think how warm and fresh the other side will feel. PERSON 2: A sea of molten rock? PERSON 1: Good for the feet. Helps exfoliate.

“Indeed it has been said that from the proceedings of her early Legislatures, it might well be imagined that Michigan sought the privileges of a state solely for the purpose of building canals, railroads and turnpikes and improving rivers and harbors.” We've always been into roads, apparently.

I feel like people think "birds are dinosaurs" is a weird fun fact that is "technically true" but I don't know how to emphasize that there are tens of thousands of species of theropod dinosaur on the planet with us right now. People keep them AS PETS. WE EAT THEM.

Deep in this Michigan copper mine, is a place only about 30 people have stepped in the last 100 years. A place still marked by the footprints of the miners who walked out more than a century ago. Recently, I got to go down there. It was, honestly, incredible. 🎥 youtu.be/cTZF4lw0Ads

In West Michigan? You can help monitor native sucker fish through this opportunity shared by @miseagrant.bsky.social! All it takes is a pair of polarized sunglasses for spotting fish and ten minutes to walk the riverbank counting and recording fish. www.canr.msu.edu/news/spring-...

Spring brings spawning fish into West Michigan streams, and you can help to monitor spawning runs in local creeks
Michigan Sea Grant is working with Shedd Aquarium, John Ball Zoo, and GVSU to learn more about migration cues for a little-known fish species, and you can be a part of it.

Somewhat ridiculously, Saturn now has 128 new moons, bring its total to 274. These are mostly tiny rocks, a few miles across, that orbit the planet backwards – but they might be evidence of a recent smashup in the planet's orbit. Story by me in The New York Times www.nytimes.com/2025/03/11/s...

The objects around the ringed planet are tiny, but some of them may have formed relatively recently in the solar system’s history.

I got to speak to third-graders today about making videos, and oh man, if it wasn't the most delightful time. I was asked so many questions. Nobody seemed afraid to not know things. Everyone wanted to talk about favorite animals. On the spot, I learned that, apparently, I really like anteaters.

Wildlife tracking tips. Thank you Patrons! www.patreon.com/c/birdandmoon
A six-panel comic titled "Wildlife Tracking Tips". In panel 1, the text says "A white-tailed deer traveled through here," and there are white-tailed deer prints in fresh snow. In panel 2, the text says "An American Red Squirrel came by," and the leap marks of a red squirrel are in the snow. In panel 3, the text says "A Snowshoe Hare passed through," and there are the distinctive fluffy-footed marks from a snowshoe hare jumping across the snow. In panel 4, the text says "The Snowshoe Hare found a sword," and one of the front paw marks in the track has been replaced with a long thin line running alongside the track. In panel 5, the text says "The Snowshoe Hare is dual wielding," and both front paw marks have been replaced with long thin lines. In panel 6, the text says "The Snowshoe Hare tamed a mount, vastly increasing its jumping distance. You should run," and the Snowshoe Hare trail runs into a deer track and disappears.

Nature valentines. Thanks to my Patrons for keeping me drawing www.patreon.com/birdandmoon
A group of six nature valentines. A picture of a bog with pitcher plants, with text saying "Our love is like a bog. Built up over time, resistant to decay, deeply interesting to just a small number of people." A yellow slime mold stretching out and exploring. "our love is like a slime mold. Collaborative, complex, at times unnerving to behold." A piece of limestone with a small trilobite in the corner. "Our love is like limestone. Layered, useful for many purposes, shaped by the friends we met along the way." A ring-billed gull with a french fry on a beach. "Our love is like a ring-billed gull. Abundant, found in North America, sometimes sustained by french fries." An Atlantic horseshoe crab walking on the sand. "Our love is like a horseshoe crab. Tough, timeless, unrelated to true crabs." A drawing of the phosphorus cycle, with arrows connecting various parts of a scene, including algae and fish and a farm and a river and a forest. "Our love is like the phosphorus cycle. Important, really hard to draw."
