BTW: The ellipsoid/datum within this data set does NOT match
the metadata description of the same map. Similar things
I observed with the geological map: The SHAPE file lacks the .prj
file, the geological map metadata refer to a third spheroid.

Either the metadata and/or the maps are wrong, and/or the various
maps of the US National Atlas use different ellipsoids/map datums
(Sphere, GRS80, WGS84 etc).

It is a bit confusing. Does anyone have more insights?
