Minerals and Rocks


Collecting rocks and minerals must be one of the world’s oldest hobbies. All that is really needed is the ability to pick up an attractive or interesting specimen that catches the eye. From the simplest collections to the very sophisticated, Pennsylvania has provided many fine and varied specimens to the world.

Rock boxes are once again available from the Survey.

There are many rock and mineral clubs around the state that can provide guidance to the beginner and comradery to the experienced collector. They also open the gates of quarries that are otherwise off limits to collectors. A list of clubs is maintained at the Penn Minerals website.

An introductory overview of the subject can be found in our Educational Series 1, Rocks and Minerals of Pennsylvania.

Pennsylvania has a state fossil. In 2004, celestine was proposed as the state mineral, but the proposal was never approved.
