One of the Sierra Club's early battles was to protect the Hetch Hetchy Valley in Yosemitee National Park. Despite the efforts of John Muir and others, a damn was built in the valley to store water for the city of San Francisco. But Muir's spirit lives on, and this month a group of dedicated citizens will be walking from Tuolumne Meadows to the O'Shaughnessy Dam to raise awareness and money in hopes of bringing the valley back.
You can get involved by pledging to one or more of the participants. You can also meet the participants at the O'Shaughnessy Dam on September 19th. Contact Jonathan Silverman at firstname.lastname@example.org to arrange rides and for more information.
