2014 Map of Spur Mountain

Water drains from these summits into an intricate network of named tributaries, such as Lone Rock Cr and Fawn Cr, eventually feeding the Ruby River and its West Fork. Notable landmarks for navigation and local history include the distinctive gap known as The Notch and the isolated Yellow Bear Lake. The map illustrates a wilderness area largely devoid of permanent settlements, focused instead on the preservation of the natural watershed and mountain environment as it remained in the early 21st century.
