Lupton saw the potential for a successful trading post on the banks of the South Platte River. He resigned his commission and returned the next year to build Fort Lancaster. Fort Lancaster operated as a fur trading post until 1844, when a particularly harsh blizzard caused the fort to close and Lupton moved his family south to an area near modern-day Pueblo, Colorado.
Later, they moved to California during the 1849 Gold Rush.
Lupton lived in California until his death in 1885.
In 1835, Lieutenant Lupton was a member of Colonel Henry Dodge"s United States Regiment of Dragoons when they passed through the South Platte Valley in what would become the state of Colorado.
