1969 Map of Triangle Mesa

About this map

The Gunnison River carves through a landscape of high mesas and deep drainage canyons along the Mesa Co Delta Co line. In the late 1960s, this area remained largely undeveloped, defined by the Denver and Rio Grande Western Railroad snaking along the riverbanks near the small settlement of Bridgeport. The map reveals a network of high-altitude terrain including Triangle Mesa, No Mans Mesa, and Horse Mesa, separated by significant watercourses like Big Dominguez Creek and Little Dominguez Creek.
