New, super-detailed Dry Falls interpretive map from the Washington Geological Survey. #iceagefloods #missoulafloods #channeledscablands #geomorphology washingtonstategeology.wordpress.com/2025/07/15/n...

@joelgombiner.bsky.social and I had a conversation with Nick Zentner yesterday about our upcoming WGS #DryFalls map. Looking for feedback before publishing. #iceagefloods #missoulafloods #geomorphology youtu.be/v01cycrCgno

Drumlinized land use, shaded by NDVI. Fields with various degrees of vegetation greenness, oriented parallel to drumlin long axes reflecting two different ice flow directions across the Green Bay Lobe, southern Wisconsin.

Just a regular reminder: the ArcticDEM is one of the most beautiful spatial datasets out there. I've been working on a large tile set for our #arctic abrupt thaw mapping activities recently and I can't help but stop and take a peek as the data rolls in.

A few of the maps and graphics I made in 2024. What climate maps do you want to see next year?

Hello! The Atlas of Design shows off some of the world’s most beautiful and intriguing cartographic design. Every two years, we publish a new volume of full-color maps, selected from worldwide competition and judged by an expert panel. Happy to be part of Bluesky! #maps #cartography #books #design

For @sciencenews.bsky.social: Trees and the fungi they depend on are being torn apart, a new study finds. As climates get warmer and drier, many trees should be migrating north—but some aren't. That could be because their fungal friends can't make the journey. www.sciencenews.org/article/clim...

Also, my little online shop is but one of many cartography shops! @pinakographos.bsky.social and I recently launched mapartists.org with 30-something (and growing!) independent map sellers. Let your favorite cartographers cover all your gifting needs!

To say: my profile pic is a LiDAR image showing the river-ghosts—historical meanders—of the Lower Mississippi. Water, wandering, wilfully. It’s by Daniel Coe, who has deep-mapped the pasts of many rivers. See more of his work at dancoecarto.com/work & below. What wild, wondrous beings rivers are.

A favorite recent project: Peakscapes. I love the layered looks you get in the #mountains, and I always want to be able to name everything in view. These designs provide a cleaner, more idealized view of the landscape than a photo can. Are they #maps? Or geographic art? I'm not sure.

It’s amazing how one “simple” trick—color-coding landscape features in bare earth LIDAR data—can increase the readability of topography. Image from the Washington Geological Survey (Washington State DNR)/Dan Coe www.flickr.com/photos/wasta... #dataviz 📊 #cartography🗺️
