2020 Map of Flagstone Mountain

About this map

The Conchas River carves a winding path through this corner of San Miguel County, defining a landscape dominated by dramatic mesas and deep canyons. To the north, Yegua Mesa and Vivian Hill overlook the complex drainage systems of Harris Canyon and Conchas Canyon. This arid ranching country is marked by essential water management features like Harris Tank and the southern Nafas Lake, which support life between the high plateaus. The topography is anchored by the prominent Flagstone Mtn and the broad expanse of Mesa Montosa to the southwest. Modern accessibility is provided by Co RD c48a, which navigates the uneven terrain where Cañada Tuloso and Salitre Cr eventually contribute to the regional watershed.
