a) Lake Bonneville

The Great Salt Lake, the largest saltwater lake in the Western Hemisphere, is a remnant of Lake Bonneville, a prehistoric lake that once covered much of modern-day Utah. This ancient lake existed during the last Ice Age and was significantly larger than the current Great Salt Lake. Over time, as the climate changed and the lake’s water levels dropped, Lake Bonneville shrank, leaving behind the Great Salt Lake as a remnant of its much larger predecessor. The lake’s history and the evidence of its ancient shoreline provide valuable insights into the geological and climatic history of the region.
