Central Pennsylvania Rock and Mineral Club

About

“The Central Pennsylvania Rock and Mineral Club, Inc. is a great resource for rock enthusiasts of all levels of interest and expertise. The club was established in 1958 with the goal of encouraging interest, enjoyment, and appreciation for rocks, minerals, gems, fossils, and lapidary arts. We are a non-profit (501c3) educational organization that is affiliated with both the Eastern Federation of Mineralogical and Lapidary Societies as well as the American Federation of Mineralogical Societies. This makes us an excellent source of information on rocks and minerals as well as providing opportunities to meet others with similar interests. If you’re a rock enthusiast, then monthly meetings are the perfect way to learn more about your hobby. We have guest speakers who give presentations on various aspects of geology and earth sciences. Monthly meetings are open to members and visitors, so feel free to come check us out! Have a younger rock enthusiast? We have a junior program for school-aged rock lovers that meets at the same time as our general club meeting. They’ll learn lots of fun stuff about rocks and get to share their hobby with other kids! Field trips are another great benefit to being a member. Open only to members, field trips offer you the inside track to interesting geological sites, so you can see first-hand how rocks are formed and what they look like. And most field trips are open to collecting, so you can expand your collection- or start a new one! Being part of the club is a great way to meet new people with similar interests and learn more about the fascinating world of rocks!

And more!

There will be demonstrations, games and interesting facts about rocks and minerals. Everyone goes at their own pace to each station in the order they choose.

Rock and Mineral Sales Table for children with affordable prices! (cash only)

Participation is limited to a first come first served basis so please sign up early! Advanced payment of $5.00 for each child will guarantee your reserved spot for the special rocks for kids event. Registration is limited so that we may be sure of having enough specimens for all of the students. Walk ins are also welcome.

Rocks4Kids Day is fun and rewarding for students in grades 1-8 and supervising adult (parents, grandparent, guardian ect). Only the student pays to register. All attendees must be accompanied by an adult. They will learn about minerals, crystals, and fossils at a series of stations and the student will receive samples to begin their own rock collection. It will take about two hours to complete the stations. Sign up for your preferred start time so that we can spread the crowd out through the day.
