Notes: I got this selenite crystal at the first Pebble Pups meeting I attended. I belong to the Lake George Gem and Mineral Club.  I researched this crystal and found lots of interesting facts. I found out that it was very unique.  This crystal was found in Oklahoma in 1970.  You can go to Oklahoma and find selenite crystals in the salt plains there.  The hourglass shaped Selenite crystals are only found on these plains. It is also the Oklahoma State Crystal.

Welcome! This is the gateway to adventure and discovery

Through this blog pebble pups and junior members of the Colorado Springs Mineralogical Society can access their lessons, work on assignments and projects, and receive details about field trips in the Pikes Peak Region. This Internet program is also suitable for young people who are interested in Earth science but do not live near a rock club or gem and mineral society or for young people anywhere who want a deeper dive into these topics. The only requirement is that all participants must be members of the Colorado Springs Mineralogical Society and must fill out the CSMS membership form (under important websites) and send their registration and membership fee in. Steven Veatch is the senior instructor and will need an email from you with your name, address, phone number, and permission from your parents to participate in this program.
