Junction Butte, Summit in Canyonlands National Park, United States

Junction Butte is a 6,400-foot-elevation summit in the Island in the Sky District of Canyonlands National Park, San Juan County, Utah. It rises 1,400 feet above the White Rim Road in less than one mile and is composed of hard, fine-grained Wingate Sandstone capped by the Kayenta Formation, forming steep cliffs over softer Chinle Formation layers.

The sandstone layers formed during the Late Triassic from wind-driven sand dunes deposited about 200 million years ago. Rivers later carved into these layers and created the cliffs and canyons visible today.

The butte's name comes from its position just north of the confluence of the Green and Colorado rivers, whose waters meet below the White Rim Road. Visitors driving that road see the butte from below; hikers at Grand View Point look down on it from the mesa rim about a mile north.

Access is via the White Rim Road, which requires a four-wheel drive vehicle and prior authorization. The road is unpaved and can be difficult to drive depending on weather, so check conditions before heading out.

Junction Butte is named for its position just north of the confluence of the Green and Colorado rivers, though the rivers themselves lie outside the butte's slopes. Its summit stands 1,400 feet above the White Rim Road in under a mile, and the butte is capped by the Kayenta Formation over Wingate Sandstone cliffs.
