Historically, the fluctuating water level of Utah's Great Salt Lake has had a great effect on people's use of the lake. When the lake began dropping after 1873, many recreational sites like Black Rock were left high and dry. This video is extracted from the 22-part video series The Geography of Utah, conceived and written by Albert L. Fisher, PhD of the University of Utah. The series encompasses the political, cultural, historical and sociological geography of the state of Utah. It describes the activities, the land, and the people. Much of the video material was videotaped on location throughout the state of Utah, giving the student and interested viewer valuable field trip experiences.
