Fort Collins Rockhounds Club Our members share a common interest in rocks and minerals. Areas of interest include lapidary work (cutting and polishing rocks, tumbling, and faceting gems), and jewelry making. Meetings feature club business discussions, rock show-and-tell, give-aways, various programs and presentations, videos, and snack/social time. The club organizes field trips within about half a day’s drive from Fort Collins, Colorado, and sponsors the annual Fort Collins Gem and Mineral Show each Winter. Visitors, including children, are always welcome to attend meetings.
