2013 Map of Big Costilla Peak

About this map

Big Costilla Peak dominates the high-altitude landscape of northern Taos County, where the border of New Mexico meets Colorado. This 2013 survey documents a complex system of mountain drainage and alpine lakes along the state line. Water from Glacier Lakes and Lake Number One feeds into high-elevation streams such as Casias Cr and Willow Cr, eventually flowing toward the Costilla Reservoir in the southern portion of the quadrangle. The topography is defined by significant elevation changes, ranging from the deep incisions of Long Canyon to the massive peak itself. The presence of Costilla Lodge near Beaver Lake suggests a localized focus for recreation or land management within this otherwise unpopulated mountain terrain. The map also captures the headwaters of numerous creeks, including Santistevan Cr and Jarocito Cr, illustrating the vital watershed role this region plays for the surrounding high desert plains.
