Wild Horse Window, Green River, USA Utah, North America

Wild Horse Window is a natural sandstone arch located in the San Rafael Swell region of Utah, near Green River.

This geological formation is characterized by its large, irregular opening carved by erosion.

Visual Characteristics

The arch is composed of Entrada Sandstone, exhibiting a reddish-orange hue. Its opening measures approximately 15 meters in height and 10 meters in width. The surrounding rock formations are layered and exhibit differential erosion patterns.

Location & Access Logistics

Wild Horse Window is situated approximately 30 miles west of Green River, Utah. Access is via I-70 West to Exit 131 (UT-24 West). Proceed 15 miles on UT-24 West, then turn north onto a marked dirt road (often referred to as the Wild Horse Window Road). This road is unpaved and can be rough; high-clearance vehicles are recommended. The trailhead is approximately 5 miles from UT-24. Parking is available at the trailhead, with capacity for approximately 10-15 vehicles. No public transport services this location.

Historical & Ecological Origin

This arch is a product of aeolian (wind-driven) erosion and differential weathering acting on Jurassic-age sandstone over millions of years. The specific process involves wind carrying abrasive particles that carve into softer rock layers, while harder layers remain more resistant, creating openings and arches.

Key Highlights & Activities

Observation of the arch formation. Photography of the arch and surrounding desert landscape. Hiking to the base of the arch. The area is suitable for desert exploration.

Infrastructure & Amenities

No permanent infrastructure or amenities are present at Wild Horse Window. Restrooms are not available. Shade is minimal, provided only by natural rock overhangs. Cell phone signal is unreliable to non-existent in this remote area.
