.... Glacial striations shown on the map were measured as part of this survey. Mineral occurrences are from MINFILE (2015) . The Deerhorn, Megabuck, Takom, and Spellbound zones are Cu-Au-Mo alkalic porphyry-type deposits occurring as quartz stockwork within the contact zones of satellite intrusion...

... attributes and some of these observations are compared with those made on other like-aged elk remains. Together, attributes of the Marmes-site big elk suggest aspects of local paleoecology at the end of the Pleistocene. The majority of the big elk remains lay on a fluvially deposited silt layer...
