The Fillmore Field Office is located in the western part of Utah in the Basin and Range province called the Great Basin. This area is dominated by Notch Peak and Swasey Peak, both reaching nearly 10,000 feet high. At one time this whole area was part of Lake Bonneville and measured over 1,000 feet deep, 145 miles wide, and 346 miles long. This massive lake dominated the landscape for at least 15,000 years, as it evaporated it left behind Utah’s largest free-moving sand dune field, now the little Sahara Recreation Area. The dunes are an ideal sand buggy playground, while the surrounding mountains are a challenge for off-road vehicles.
