2015 Map of Piyau Dome

About this map

Sierra National Forest defines this high-elevation landscape within the Sierra Nevada mountains, centered on the granite landmarks of Piyau Dome and Jackass Butte. The topography is characterized by a series of high meadows and drainage systems, where water collects in areas like Arnold Meadow and McCreary Meadow before feeding into the San Joaquin River to the south. Distinctive geological features such as Arch Rock, Jackass Rock, and the curious Hells Half Acre punctuations of the high country terrain. The map traces the intricate hydrography of Jackass Cr and its various branches, alongside Reconnaissance Cr, illustrating how the watershed moves through the dense forest land and across the Madera and Fresno County line.
