Career
The present day, Fort Vasquez, located on Highway 85, next to Platteville, Colorado, is a reconstruction. After selling the trading post in 1840, Andrew left the mountains and was seen in El Pueblo around 1844 and 1845 (present day Pueblo, Colorado), traveling along the Arkansas River, following herds of American Bison. He was killed, in an encounter, with a grizzly bear, in Southern California in December 19, 1853 or 1854.
Sources variously, place the site of his death, as Santa Monica Canyon or nearby, Malibu Canyon.
