Hikers, do you want to learn a bit of field geology and map reading skills while hiking, and sometimes camping in the western USA? Interested in participating in Geo-hikes and trips to scenic, and sometimes remote, locations? Want to learn about the fascinating history of the earth at these locations while on the move? If yes, then events hosted and led by the Geologic Maps Foundation might be of interest to you. Plus, the participants meet others with similar interests while getting great exercise. You do not have to be a geologist to attend but an eagerness to learn some basic geology and map reading skills are a must.
Professional geologists can share their knowledge and experiences (as co-leaders) with geology students and non-geologists while exercising and returning to, for many, why they got into geology in the first place.
Geology students (at any level) will gain field experience, an opportunity to interact and make contacts with professional geologists that could be helpful in the future, and with lots of outdoors exercise in interesting geologic settings.
There are a number of geo-hikes scheduled for the 2023 season and more will be added. "Spreading the word" about these events is most appreciated. Interaction of professional geologists and geology students with hikers, that are not geologists, informs the public about geology and its importance.
Most of the Geo-hikes events and courses are free while a few are fund-raisers and require a donation to cover expenses and operating costs for the longer trips. The Foundation is a tax-exempt nonprofit ,IRS 501 (3) (C), with a scientific educational and research focus. Donations are tax deductible and go towards the expenses of the event and the operating cost of the Foundation.
Geo-hikes also organize and lead customized geologic field trips for professional organizations and companies to various areas in the western US and Baja California. Trips are great educational and team building experiences. Please email us at: geologicmapsfoundation@gmail.com for more information about the customized trips.

Geology Walk, Taft Gardens Event, April 4th @ 9:00 AM
Taft Gardens/CEF Botanical Gardens, 2158 Baldwin /Rd., Ojai, CA, USTHIS POSTING IS FOR ANNOUNCEMENT ONLY. YOU CANNOT SIGN ON HERE AND IF INTERESTED IN ATTENDING YOU MUST PURCHASE A TICKET THROUGH TAFT GARDENS, MORE INFO AND PURCHASE HERE: https://www.taftgardens.org/events
IN THE PAST, THESE EVENTS FILL-UP QUICKLY.
Join Thom Davis on an academic geology walk at Taft Gardens where you will discover an ancient story told under your feet. Our geology walk will view and discuss the rocks, faults, and folds of the Taft Gardens Nature Preserve and adjacent Ojai area. You will travel back in time to the Oligocene (16-34 million years ago) and Eocene (~36-38 million years ago) to learn about the origins of our local rock formations, the Sespe Formation and Coldwater Sandstone. The Sespe Formation is characterized as a non-marine deposit of sandstone, conglomerate, and siltstone with a distinctive red color. The Coldwater Sandstone is a shallow-marine deposit formed in beach, estuary, and sub-tidal paleo-environments making it rich in fossils. Learn how these rocks were seismically uplifted and then down-cut from the erosion of Santa Ana Creek to form the narrow valley where we are situated.
This walk is for anyone who wants to discover the story of the land and no prior geology knowledge is needed. Bring a notebook to take notes if you wish or questions if you have some geology knowledge already. This walk will take place in the Nature Preserve and cover uneven ground. Please bring trekking poles if you wish and be prepared to walk over a mile of hilly terrain.
