Lab 3: Morphometrics

The Logan River is located in primarily in Northern Utah, though its headwaters originate just north of the Utah-Idaho border in the Bear River mountains. The lithology is primarily composed of Paleozoic limestones and dolomites, making the basin's runoff rather alkaline. The watershed is within the horst-graben mountains of the Basin and Range geologic province which was largely inundated by massive lakes during the last glacial maximum (~20,000 years ago). The Logan River drained directly into one of these lakes, Lake Bonneville, until the lake catastrophically drained into the Columbia River Basin and further retreated due to a warming climate. The Logan River now drains into the Bear River on its way to Great Salt Lake and serves as a recreational hub for residents of Cache Valley and all of Utah.
