Angeles Chapter

Angeles Chapter of the Sierra Club

Continuing Our Second Hundred Years Of Activism for the Environment

On November 1, 1911, 75 Sierra Club members gathered in downtown Los Angeles to sign a petition calling for the creation of a "Southern California Section," the first local chapter in the history of the organization that John Muir founded in San Francisco in 1892.

Today, the Sierra Club Angeles Chapter covers Los Angeles and Orange Counties and includes 14 regional groups (organized by geographical area) and 32 outdoor activity sections and committees (organized by interest). Chapter coordination and oversight is provided by an elected volunteer Executive Committee; the chapter also employs 4 staff who work with volunteer leaders to advance its priorities.
