- Comments
- EgPm-3, Mona Lisa: Four components were identified at Locality C, two of them above and two below Mazama tephra. The upper post-Mazama bone bed contained one large side-notched point. The lower post-Mazama component represents a winter season (January to March) bison kill with two projectile points of the Mummy Cave series. No other occupation at any locality can be identified culturally, but the pre-Mazama bone bed at Locality A represents an autumn bison kill (October to December).
