Huerfano Butte

Huerfano Butte is a volcanic plug or hypabyssal plug located north of Walsenburg in Huerfano [County, Colorado|Huerfano County], Colorado, United States. Named Huérfano by early Spanish explorers, it rises above the south side of the Huerfano River with its peak about above the floodplain.
A historical marker was placed on the east side of Interstate 25 to commemorate its position near the Trapper's Trail to Taos, New Mexico. It was passed by John [Williams Gunnison] and John C. Frémont during their surveys for the railroads. Other places are now also named after the butte, Huerfano County and Huerfano River.
