Statement of Purpose:

"To explore, enjoy and protect the wild places of the Earth; to practice and promote the responsible use of the Earth's ecosystems and resources; to educate and enlist humanity to protect and restore the quality ofthe natural and human environment; and to use all lawful means to carry out these objectives."

We are the San Gorgonio Chapter of the Sierra Club and we span both San Bernardino and Riverside Counties, so yes, we are involved in a large and complex geography.   Our interests range from the wildnerness and open spaces of our Southern California deserts and mountains to the intense development and congestion of our urban cities and inland valleys.
