What we’re about
The Sierra Club is America's oldest, largest and most influential grassroots environmental organization with the Mother Lode Chapter serving 24 Northern California Counties. Enjoy a variety of events offered by three of the Mother Lode Chapter Groups: "Stockton" Delta-Sierra Group (DSG), "Modesto" Yokuts Group (YG), and "Sonora" Tuoloumne Group (TG) which make up the Central Gold Country. Hiking, gorge scrambling, kayaking, skiing, biking, camping, service trips and other events are lead by Sierra Club trained leaders.
Most leaders have many years of experience leading hikes and often have a great knowledge of many open space areas and parks in the Central Gold Country: Mokelumne Wilderness, Eldorado National Forest, Carson-Iceburg Wilderness, and Yosemite; and the East Bay and Coastal Bay Area. Leader styles vary greatly. Some are very fast paced with few stops; others travel at a very slow pace and stop frequently. You are required to be properly equipped and able to stay with the group so be sure to check with the leader if you have any questions about the outing. The difficulty of each trip is usually rated with a Classification that is explained in the Important Outings Information. Also, each outing participant must have the Essentials, which are also listed in Important Outings Information.
All adults are welcome, including those who are not members of Sierra Club. We generally meet at a designated local parking area and then carpool to the event site (though Sierra Club does not officially organize carpools) which can be located nearby or several hours away. We also have fun off the trail with social events such as dinners, movie nights, Christmas Parties, and potlucks.
Happy Trails!

Mount Diablo's Geological Complexity
Fireside Room, Central United Methodist Church, 3700 Pacific Ave, Stockton, CA, US6pm start time (NEW EARLIER TIME)
Mount Diablo is our region’s most visible landmark. Diablo is geologically complex, with a core of ancient oceanic basalt jutting up against folded and faulted metamorphic and sedimentary rocks. Attendees will get an understanding of the fascinating geology that created this magnificent mountain.

She earned her B.S. in Geology from Missouri State University, her M.S. degree from University of Missouri-Columbia, and has over thirty years soil and groundwater contamination cleanup experience.
