Summary

The Ogden Bay 7.5′ Quadrangle, located in north-central Utah, showcases the intersection of the Weber River and Great Salt Lake. Within the map's borders, one can find a diverse range of geological features such as young lacustrine, marsh, deltaic, and alluvial deposits, formed during the rise and fall of Late Pleistocene Lake Bonneville (30,000 to 13,000 years ago) and the Holocene Great Salt Lake (13,000 years ago to present). In the northwest corner, stands Little Mountain, a Neoproterozoic geological formation made of diamictite, greenstone, slate, and carbonate. This mountain holds evidence of past shorelines, shaped by fluctuations in the level of Lake Bonneville. The Ogden Bay Wildlife Management Area, which serves as a sanctuary for various waterfowl, is also included in this area.
