Call it returning to our cave person roots. In recent years, rockhounding — the simple act of searching for cool rocks, gemstones, and fossils on shores or in riverbeds — has surged in popularity.

Rockhounding is an accessible, beginner-friendly way to get outside and enjoy the thrill of the hunt. Before you begin searching, here are a few tips to keep in mind, as well as some nearby places to start.

Where are the good rockhounding spots around Indy?

This gem of a map makes it easy to find every confirmed rockhounding locale within 150 miles of Indy. Users have reported finding everything from amethyst to moonstone in nearby creeks.

The Reddit rockhounds also have a few of their own suggestions:

“There is a wooded park — Marott Park — at 75th and College Ave. Apparently if you walk far enough back, you run into the White River. I have read that you can find some good agates there.” — AMLJup
“Sugar Creek in/around Crawfordsville is better known for crinoid fossils, but I’ve found some great rocks too.” — possumgal0808

Are there any rockhounding rules?

Some areas, including National Parks, are strictly off limits for rockhounding. Violators could face criminal penalties. Most wilderness areas and national monuments also prohibit collecting; if you have doubts, check in with the place you wish to visit to make sure you’re in the clear.

Many rockhounds also follow an unofficial code of ethics, which encourages participants to respect nature + the laws of the area, refrain from taking more rocks than can be reasonably used, and help keep our environment clean and healthy.
