The Oquirrh Mountains is a mountain range that runs north-south for approximately 30 miles (50 km) to form the west side of Utah's Salt Lake Valley, separating it from Tooele Valley. The range runs from northwest Utah County–central, east Tooele County, and ends north at the south shore of the Great Salt Lake. The highest elevation is Flat Top Mountain (Utah) at 10,620 ft (3,237 m). The name Oquirrh was taken from the Goshute word meaning "wood sitting."
