New blog post about maps I made for a presentation with @kennethfield.bsky.social and @johnnelsonmaps.bsky.social at #esriuc2025!

We each made three maps with the same dataset to highlight different thematic mapping approaches. Loved presenting with Ken and John!

Camp Mystic’s leader got a ‘life threatening’ flood alert. They evacuated an hour later.
More than an hour passed between Camp Mystic receiving a severe flood warning and a decision to evacuate young campers asleep in cabins by the Guadalupe River.

Next week a stack of 900 books is going to arrive at The Map Center as part of my first ever book distribution deal. Cartographer Damien Saunder wrote "Maps on Vinyl" as a celebration of maps that appear on album cover art and the places that made the music. I'm so excited! Booksellers DM me.
