Welcome to the Range of Light Group!  

The Sierra Club Range of Light Group, part of the Sierra Club Toiyabe Chapter, represents the Sierra Club in the Eastern Sierra; in Mono and Inyo Counties. The Eastern Sierra is the homeland of the Nuumu and Newe People and has been since time immemorial.  It is a beautiful area rich in natural, scenic, cultural, and recreational values and benefits. We engage both our members and a wide array of local stakeholders in our work to safeguard our region's diverse landscapes and outdoor opportunities. Membership and participation in the Range of Light Group activities are open to all interested in enjoying, protecting and exploring the Eastern Sierra.

 "Sitting islanded on some grey peak above the encompassing wood, the soul is lifted up to sing the Iliad of the pines." Mary Austin.
