Eagle Rock is a renowned destination for rock collectors, offering a variety of fascinating rocks and minerals.

Collectors may also discover other remarkable specimens, such as moss agate, jasper, and chalcedony, making Eagle Rock a rewarding spot for rockhounds.

Eagle Rock Minerals

Plume Agate: Black and brown varieties with intricate, feather-like patterns.
Moss Agate: Agate with mossy, plant-like inclusions in green, red, or brown.
Banded Jasper: Bright red, orange, or brown jasper with striking bands.
Chalcedony: Translucent stones in shades of white, gray, or blue.

Occasionally, lucky collectors might uncover small pieces of petrified wood or quartz crystals.
