This Meetup group is open to hikers, professional geologists, geology instructors, and geology students. 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. Past and future events are posted at https://www.meetup.com/Geo-hikes/

Please share our efforts with any interested party or organization.
