Interesting, but you're missing geologically important proglacial lakes, like Lake Missoula and Lake Agassiz.

Very cool, the interactivity of this makes this a much better learning tool than a set of static images (for me, at least).

One minor suggestion: on mobile put the date scrubber on the bottom, otherwise my thumb gets in the way of the UI while sliding back and forth through time :)

Also, I’m not sure if a log scale for time makes sense in this case. It confused me for a second, at least.

Great job, thanks for sharing!

Nice work! This is like a much better version of Ancient Earth[0], which I made ~10 years ago using GPlates[1]. I like your approach of rendering the map itself from data, which makes it continuous, rather than just wrapping map textures around a globe.
