Figure 1. In mid February a team of scientist from across the country met a Salt Lake (Lake George) in Kidder County to take cores of the bottom sediment. The team included Ms. Jamie Toney, graduate student, BrownUniv., Dr. Sheri Fritz, Univ. of Nebraska, Dr. Paul Baker, Duke Univ. and Dr. Eric Grimm, Illinois State Museum. Also present were Dr. Allen Ashworth NDSU and several geology students.

Figure 2. This figure shows the coring device ready to be lower through the ice. A site on the lake previously located with sonar and GPS was used. The site was in approximately 42 feet of water. The coring device was lowered to the bottom and a 3 foot core was captured brought to the surface stored and the process repeated.

Figure 4. Dr. Sheri Fritz look on as the core is being extracted from the coring device. A total of 42 feet of sedement was removed from the lake bottom.
