- Comments
- EgPt-17: The site is on the east side of a bedrock peninsula extending into the south shore of the lake. A backhoe trench revealed the presence of four cultural levels in about 4.5 m of aeolian deposits overlying sand and gravel. Two levels are above and two below a tephra layer presumed to be Mazama tephra.
