The earliest intact archeological deposits in the park have been found at a site on the shore of Yellowstone Lake. The site was excavated because it was at risk of erosion, and revealed evidence of a 9,350-year-old camp where several families appear to have spent time. People probably used this area in the summer while hunting bear, deer, bighorn, and rabbits, and perhaps making tools and clothes. Artifacts dating to 3,000 years ago have also been discovered on islands in the lake, leading some archeologists to speculate that indigenous peoples used watercraft to travel there.
