Detail of diorama of Paleomarine Period, Southeast Alaska. Source: Tongass NF
The Tongass National Forest in Southeast Alaska has a lot of interesting stuff online. I’ve just found they have a cool set of dioramas illustrating different time periods from the last 10,000 years of human history (scroll to the bottom of this page). These start with the palaeomarine period, about 10,000 years, a section of which is seen above. Some of it is conjectural of course and I am not going to go to the wall defending its veracity, but I do appreciate the National Forest making an effort to present the past in an accessible way.
