House Range BLM Riding

The House Range BLM riding zone encompasses the Swasey Mountain and House Range country of Millard County in west-central Utah, approximately 40 miles west of Delta in the remote Great Basin interior where Utah grades into the Nevada-Utah border desert. Managed by the BLM Fillmore Field Office, the House Range represents one of the most remote and least-visited OHV riding areas in Utah, giving riders the kind of genuine open-desert solitude that is disappearing from more accessible BLM destinations across the West. The House Range is a significant fault-block mountain: the range rises from 4,500 feet in the surrounding basins to over 9,600 feet at Swasey Peak, with the exposed Cambrian and Ordovician sedimentary bedrock producing the banded cliff faces, limestone scree, and rocky summit terrain that distinguishes the House Range from the rounded sagebrush-covered ranges typical of the Great Basin. Trilobite fossils are abundant in the Marjum Formation at House Range, the area is a significant paleontological destination alongside its OHV use, and riders will pass through terrain where amateur fossil collecting is permitted on BLM land under standard casual-use rules. ATVs, UTVs, dirt bikes, and 4x4 trucks are all permitted on designated BLM routes. Utah OHV registration is required. Dispersed camping is available throughout the BLM district under 14-night limits. Cell coverage is minimal to nonexistent across most of the range; plan accordingly. BLM Fillmore Field Office (435-743-3100) manages current route designations and posts closure information during wildfire and winter weather events.
