2011 Map of Grays Peak

About this map

Sunshine Mine and the Mascot Mine sit deep within the high-elevation drainage of the East Fork Wood River in this 2011 survey. The landscape is defined by its extreme verticality, dominated by the massif of Grays Peak and Old Hyndman Peak. The hydrology of the area is characterized by alpine tarns and steep drainages, including Arrowhead Lake, Windy Lake, and the tiered Upper Box Canyon Lake and Lower Box Canyon Lake. Transport through this difficult terrain is restricted to high gaps like Johnstone Pass and P K Pass. The map details a network of named gulches and canyons, such as Snowslide Gulch, Cabin Gulch, and Brocky Canyon, which funnel seasonal runoff into the Little Wood River and its various tributaries like Iron Mine Creek and Chaparral Creek.
