Volunteers Are Needed
The Denver Gem and Mineral Show is organized and run by volunteers from the eight mineral clubs in the metro area, including the Flatirons Mineral Club. At the show, our club has a table to highlight our club to the public and educate children about rockhounding. Both the show and our club table need volunteers and two hours of volunteer time equals full admission to the show. Plus, the display case at our club’s table needs specimens collected during field trips the summer.

Here is how you can help:

For our Club Table: Our club table will feature information about our club, games for the kids, specimens for the public to learn more about our hobby, and a display case with specimens from our field trips. We need volunteers at our table on Friday, Saturday, and Sunday. Please contact Dennis Gertenbach at to volunteer for a time slot.

For the Club Display Case: We want to highlight some of the year’s field trips by displaying specimens we collected in the club display case. Please bring your specimens to the September club meeting or contact Dennis Gertenbach at to arrange to pick up your specimens for display.

For the Show: There are many areas in which your help is needed, including admissions, security, selling grab bags and posters, show set up, show take down, hospitality room, and volunteer check‐in. To learn more about the duties of these jobs and to sign up for a time slot to work, please contact Gerry Naugle at
