1966 Map of Summit Peak

About this map

The Continental Divide winds through the high country of southwest Colorado, marking the boundary between Archuleta and Conejos counties. This mid-century survey captures the high-altitude hydrology and transit routes that defined the South San Juan Wilderness and adjacent national forests before modern infrastructure. The map documents a complex network of pack trails, such as the Little Blanco Trail (Pack) and Quartz Creek Trail (Pack), which served as the primary arteries for movement through this alpine environment. High-altitude landmarks like Montezuma Peak and Summit Peak overlook numerous glacial features, including Fish Lake and Lake Ann. The drainage patterns are clearly defined, showing the headwaters of the Rio Blanco flowing west and the North Fork Conejos River flowing east, while the San Juan Stock Driveway indicates the seasonal movement of livestock across this terrain.
