About this map

Big Rock Mountain anchors this high-elevation wilderness in Idaho County, where a complex network of ridges and drainages defines the terrain. The landscape is characterized by prominent summits like North Peak and Frisco Peak, and the sharp divides of Blacktail Ridge and Sixtytwo Ridge. This survey captures the pristine hydrography of the region, tracing the paths of Rhoda Creek and Lizard Creek as they cut through the steep topography.

Geographical landmarks such as Bear Wallow and Meeker Point serve as essential reference points in this undeveloped area. The map illustrates the convergence of multiple forks, including Saddle Fork and the West Fork Three Links Creek, highlighting the intricate watershed patterns that feed the larger river systems of the Nez Perce-Clearwater region. This 2011 edition remains a vital record of the interior mountain character before significant environmental or modern infrastructural shifts.
