Huerfano Butte, Volcanic summit in Huerfano County, Colorado, USA.

Huerfano Butte is a volcanic plug, or hypabyssal plug, 8.8 miles (14.1 km) north of Walsenburg in Huerfano County, Colorado. It stands on the south side of the Huerfano River, its peak about 200 feet (61 m) above the floodplain, and reaches 1,877 metres above sea level.

Huerfano Butte is a volcanic plug, a mass of magma that solidified underground and was later exposed by erosion. A historical marker on the east side of Interstate 25 notes its position near the Trapper's Trail to Taos, New Mexico. John Williams Gunnison and John C. Frémont passed the butte during their railroad surveys.

The name Huerfano comes from Spanish explorers who called this place 'orphan' because of how alone it stands in the landscape north of Walsenburg. Local people use it as a landmark to navigate the otherwise flat terrain.

Visiting this butte requires obtaining permission from local landowners since the area is privately held. Bring plenty of water and watch for loose rocks and cacti while exploring the slopes.

A historical marker on the east side of Interstate 25 notes the butte's position near the Trapper's Trail to Taos, New Mexico. Both John Williams Gunnison and John C. Frémont passed the plug during their railroad surveys, and Huerfano County and the Huerfano River take their name from it.
