Welcome Rock Lovers! Rocks Rule!

The Rock Hobby Club of Greater Saint Louis formed in 1960 and was incorporated as a nonprofit organization in the State of Missouri in 1973 as a educational and social group of dealers of Earth Science Hobby Materials. The club sponsors an annual show in March each year.

As an organization we seek to acquire and disseminate knowledge of the earth sciences, rocks, minerals, fossils and lapidary.
