Add An Atlas of North American Rivers to the list of Daniel Huffman’s long-unfinished projects that suddenly got finished lately. It’s a 48-page PDF of diagrammatic maps of North American river systems, from Alaska to Guatemala. The PDF can be downloaded here; if there’s interest he’ll do a hardcopy version, and, of course, prints are available for sale.
Cartographic Beasts of North America is an interactive story map from the Harvard Map Collection. It zooms in on various mythical and real creatures embellishing a 19th-century copy of a 17th-century map of North America, ranging from cows and beavers (real) to hippocampi and manitous (um, not).

Since 2014 Anton Thomas has been working on a large and detailed hand-drawn pictorial map of North America. Done on a 120-×-150-cm piece of art paper with coloured pencils and pen, and full of little pictorial details, The North American Continent has taken more than 4,000 hours to draw—and re-draw. In an update earlier this month, Anton estimates there are still 200 hours of work remaining; he expects to be done by December, with prints going on sale early next year.
The map was the subject of two talks Anton gave at NACIS last year: see Drawing a Continent by Hand and Methods of a Hand-Drawn Map. And take note: Anton lives in Australia, but at the moment he’s in the U.S. to give talks and work out printing and distribution. He’ll be giving a presentation tomorrow evening at the Leventhal Map Center at the Boston Public Library. (Another talk is scheduled for October 24 at the Rumsey Map Center in San Francisco Stanford.)
Geoff Zeiss posts about the forthcoming NATRF2022 datum, which will replace NAD 83 and NAVD 88 in 2022. It will address the shortcomings of the earlier datums and for the first time provide a common datum for Canada, the U.S. and Mexico. “Practically,” Geoff writes, “this means that elevations may change by up to a meter and horizontal location by up to 1.5 meters. The actual corrections to elevations and horizontal locations will depend on where you are in North America. The greatest changes are in the Pacific Northwest and the least in the southeastern U.S.” [Dave Smith]
Migrations in Motion models the average directions wildlife will need to move in order to survive the effects of climate change. As Canadian Geographic explains, “As climate change disrupts habitats, researchers believe wildlife will instinctively migrate to higher elevations and latitudes, but for many species, that will mean navigating around, over or through human settlements and infrastructure.” The map, the design of which is modeled on the hint.fm wind map, covers both North and South America and does not purport to model the path of individual species; rather it’s an average based on computer modelling.
