>>2528306I was just learning about clay plain forests in New England. when the glaciers receded the area of quebec/lake champlain was an inland sea for a bit before draining, and the former seabed became forest with a dense clay for its soil. By modern times something like 1% of it is left because it made for good farming for colonists and is now conventional soil in most places. It has a different tree composition than other forests of the area now so when you go to preserved sites its one of the few sites where you'd see some tree species in the whole region.
