The Centennial Group of the Georgia Chapter of the Sierra Club was organized in 1992, the one hundredth anniversary of the Sierra Club. Our members from Cobb, Cherokee, and North Fulton counties volunteer to educate, help, and encourage our fellow citizens to protect Georgia?? "!s environment for our children, grandchildren, and beyond.

We meet on the first Thursday of each month at Life University. We host a variety of programs relating to our goals or simply about Georgia's natural beauties. We also hold free outings for members and nonmembers.

March 4th Program: Hiking the Pacific Crest Trail

Presenter: Susan Caster

Description: Sierra Club member Susan Caster will recount her through-hike adventure along the Pacific Crest Trail in 2014. The presentation of her months-long life on the trail covers routes, gear, other hikers, trail angels and weather issues. Pictures include landscapes, plants, animals and hikers. Susan has a degree in zoology and previously worked for the Georgia Department of Natural Resources. She lives in Roswell, GA.

The Pacific Crest Trail (PCT) spans over 2,650 miles from Mexico to Canada through California, Oregon and Washington. If you’ve seen the movie or read the book Wild by Cheryl Strayed, you will love this program.

URGENT: For March only we are meeting on Wednesday (March 4) and NOT on Thursday (March 5).
