Utah's Great Salt Lake is a primary link in the migratory flyway between Canada and Mexico. The lake shore provides resting and feeding grounds for millions of migratory birds. Most birds land in one of the five bird sanctuaries that border the lake. The largest, the Bear River Refuge, is located at the mouth of the Bear River. This video is extracted from the 22-part video series The Geography of Utah, conceived and written by Albert L. Fisher, PhD. The series encompasses the political, cultural, historical and sociological geography of the state of Utah. It describes the activities, the land and the people.
