| 3-D Subsurface Model
A perspective block diagram of the top of the Pleistocene shows it's relative relief below the lake. The surface approaches the lake bottom at Goose Pt., and drops away to over 18 meters in the southwest portion of the lake. A dredge pit along the south shore allowed sampling access to the Pleistocene surface deep below the lake bottom. |
