1969 Map of Triangle Mesa

About this map

Gunnison River canyons and high plateau formations dominate this 1969 survey of the Mesa and Delta County border. The Denver and Rio Grande Western railroad follows the river's winding course through the northeast corner, passing the settlement of Bridgeport and the geological landmark at Tunnel Point. The landscape is a network of arid drainage systems, including Big Dominguez Creek and Poison Canyon, which have carved deep paths through the surrounding tablelands. Evidence of human activity and ranching history appears in the form of numerous Jeep Trails and the Bar X Bench Stock Trail, providing access to isolated areas like No Mans Mesa and Cactus Park. Small-scale mineral exploration is visible via Prospects located near Star Mesa, reflecting the region's history of rugged land use and topographic isolation.
