Needle Mountain is a 6,620-foot (2,020-meter) elevation summit located in Capitol Reef National Park, in Wayne County of Utah, United States.

[3] The free-standing Needle Mountain towers 240 feet (73 meters) above its surrounding terrain, which is within the Fremont River drainage basin.

[4] Needle Mountain is composed of unfractured Entrada Sandstone which was originally deposited as sandy mud on a tidal flat and is believed to have formed about 160 million years ago during the Jurassic period as a giant sand sea, the largest in Earth's history.

Long after these sedimentary rocks were deposited, the Colorado Plateau was uplifted relatively evenly, keeping the layers roughly horizontal, but Capitol Reef is an exception because of the Waterpocket Fold, a classic monocline, which formed between 50 and 70 million years ago during the Laramide Orogeny.

This desert climate receives less than 10 inches (250 millimeters) of annual rainfall, and snowfall is generally light during the winter.
