It was located very near the ancient trail over Mosca Pass and east to Badito, Colorado and Greenhorn Mountain, all within the Sangre de Cristo Mountain Range. Apache, Comanche, and Utes had used the areas trails that then began to be used by French trappers. It was a route that continued to be used by Utes for travel to and from hunting grounds and by raiding parties in the 19th century. Sharp traded with the Utes, who liked the flashy military uniforms that he imported from Union Army and English warehouses. Chief Ouray and his wife Chipeta were regular visitors, who had their winter camped near the post and along Huerfano River and had close relationships with family members. European settlers also used the Trapper's Trail to travel through Sangre de Cristo Pass to the San Luis Valley and Taos, New Mexico. Sharp sold goods brought to the post via wagon train. He hosted horse races for Native Americans and settlers.
