|We had 300 miles and wanted to get a early start so left about 7:30. hanWhat was seen along the route more antelope. We could see the coal plants sending out not real dark emmisons but there was a dark cloud hanging over the area's. Before we left Wyoming I check my app History here. The town of Kemmerer was where James Cash Penney opened the first shop here, in what would grow into a national chain of deparment stores! As we continued on 80 what surprised us was the drop in elevation on 80 towards Salt Lake City. We then crossed over the great Salt Lake covers more than 2,000 miles and lies on the remnants of the ancient Lake Bonneville, which existed 10,000-30,000 years agao. The Great Salt Lake contains 4.5 billion tons of salt and is two to seven times saltier than ocean water. Then there is the Bonneville salt flats where a lot of speed records have been broken.
