Description:
This guide introduces visitors to the glacial and postglacial geology of the White Mountain National Forest in western Maine. The discussion covers the timing of the glaciation (the Laurentide Ice Sheet, 25,000-13,000 years ago) and the numerous features left behind: erosional features such as high cliffs, grooves and striations; depositional features such as till, erratics, and glacial lake deposits; and deposits reworked by meltwater streams such as outwash, alluvial fans, and stream terraces. Permission and access information, directions, and references are included.
