- Comments
- DjPp-100, Eagle Cave: This is a solution cavern with stratified deposits located about 91 m above Crowsnest Lake, near the Continental Divide. Bryan believes that the GSC date suggests that accumulation of part of the upper layer was very recent and perhaps includes material brought in (and possibly burned) by recent cave explorers. The artifacts in the layer are undoubtedly older than the date. The Gakushuin date places deposition of the bone bed prior to the Late Wisconsinan and shows that Crowsnest Pass was covered with ice >90 m deep some time during the Late Wisconsinan. The cave contained no evidence of previous glaciation.
