Is there some kind of prize for scoring the epidemiological hat-trick of back-to-back flu, covid, and pneumonia? Asking for a friend with a 2yo in daycare. (And who is on his fourth course of antibiotics in three months.)

50 in less than 4 months! Itโ€™s good to have work but yikes - that kind of pace would leave me in need of therapy.

Hot take: most maps of the Black Death are outdated and misleading. I made a better one.

Y'all, having a toddler is no joke. They are just adorable little epidemiological hurricanes. In the last five weeks, I have had pneumonia (twice), strep throat, a skin infection, and viral pinkeye. I spent Christmas bedridden with a 40 degree fever. It's just relentless.

It was great fun to make this animation for NiCHE! They were my first environmental history community back in my U of T days and it was a delight and privilege to return their kindness with a nifty map. #envhist #envhum #gischat #cdnhist #histgeog

It's #StarTrek Day. I can't overstate how important this franchise was to me growing up and how relevant it remains to me today. But the fact that the weasels at Paramount are profiting from its utopian vision of the future makes my skin crawl. It's also mostly kept me away from the new shows.

I did this for the Yucatรกn peninsula from 1550 to 1690 in my PhD and even in the tiny number of documents that still exist the depredation of empire was just astonishing. It enrages me when I think of that playing out across a whole empire for centuries. Itโ€™s time we started collecting the receipts.

A complete dataset of all archival records detailing colonial Spanish taxation/appropriation/forced sale of goods/currency/labour from indigenous communities across the empire from 1500 to 1820. A full accounting of the wealth and work stolen by the colonial project with coordinates. #gischat

A map entitled "The Province of Yucatรกn in the Early Colonial Period" showing the Yucatรกn Peninsula, Mexico in the seventeenth century. The extent of Spanish control is demarcated as covering the northeastern third of the Peninsula, with both the interior and eastern coast labeled as beyond Spanish colonial influence. The provincial capital of Mรฉrida and the Spanish towns of Campeche in the southwest and Valladolid in the east are labeled, as are prominent Maya towns called "cabeceras," through which the Spanish extended their influence into indigenous society and territory. Major roads criss-cross the region under Spanish control linking major towns and cabeceras together and connecting them to port cities dotted along the coast. The following approximate political regions are prominently: Sahcabchรฉn (extreme southwest), Champotรณn (far southwest, north of Sahcabchรฉn), Camino Real Alto and Camino Real Bajo (north of Champotรณn and following the highway from Campeche to Mรฉrida along the western coast), Sierra (along a ridge that extends from northwest to southeast across much of the Peninsula), Costa (the northern central coastal region), Beneficios Bajos (between Sierra and Costa, essentially in the central region of the area under Spanish control), Dzonot (a small district east of Costa and largely uninhabited), Tizimรญn (in the northeast, east of Costa and Dzonot), Chancenote (the extreme northeastern part of peninsula under Spanish control), Chancenote (south of Tizรญmin and north of Valladolid), Valladolid (in the central eastern region, named after the eponymous Spanish town), Beneficios altos (south of Valladolid and southeast of Beneficios Bajos), and Bacalar (in the extreme southeast, and abandoned in around 1650). A large uncolonized region called the "Montaรฑa" or Borderlands is also labeled, beginning south of Sierra and extending southwards off the map.

Not sure why it's showing up in lower res, but it looks good on my desktop - try that. If it doesn't work I'll root around for a less compressed version.

Yes! For maps from scratch: No labels smaller than 6pt, no lines thinner than .3pt, and at least 25% K values between shades of gray (so you really only have 3 shades to work between black and white). For conversion from color to grayscale: Start over ๐Ÿคฆ๐Ÿปโ€โ™‚๏ธ

I'm currently working on an atlas of environmental history with a few historian colleagues of mine. It won't be ready for a few years, but here's a sneak peek.

I do maps for museums too! This map of early civilizations in Africa was on the wall at the @metmuseum.bsky.social last year, and I've got another 30-or-so maps going up at the Met when they finish the Rockefeller Wing renovations later this year!

I also occasionally faff about in Blender, where I made this map of the solar system for @dagomardegroot.bsky.social and this wall map of a land parcel in New Mexico for a friend.
