Fort Lupton, Weld County · Colorado · Fur Trade Era
History & Significance
Lancaster Platt Lupton, born in New York in 1807 to a lawyer's family, attended West Point and graduated in 1829. As a first lieutenant, he participated in Colonel Henry Dodge's 1834–35 expedition to the Rocky Mountains, where he recognized the trading post's potential in the South Platte Valley.
After being threatened with court martial for criticizing President Andrew Jackson, he resigned his commission, and with financial backing from Missouri trader Hiram Rich, Lupton returned to Colorado in 1836 to build his trading post. His initial log shelter evolved into a two-story adobe fort constructed with skilled workers from Taos, New Mexico.
Fort Lupton was one of several trading posts along a 13-mile stretch of the South Platte River, including Fort Jackson, Fort Vasquez, and Fort Saint Vrain. Located on the Trapper's Trail between Laramie, Wyoming and Santa Fe, the fort served as a rendezvous where trappers and Native Americans traded buffalo hides and beaver pelts for food, cloth, blankets, tools, and weapons.
In the early 1840s, the fur trade collapsed and the trading posts closed. After 1845, the structure was repurposed as a stagecoach station during the Colorado Gold Rush and Civil War, then served as a private home and ranch headquarters before deteriorating into a livestock corral.
