In this comprehensive guide, we’ll explore the top 10 rockhounding sites across the state, along with essential tips to make your rock-hunting adventures both successful and memorable.
Before we dive into the specific locations, it’s important to note that rockhounding in Oregon requires a mix of patience, knowledge, and respect for both private property and public lands.

Essential Equipment for Oregon Rockhounding
Before heading to any of these sites, ensure you have the proper equipment. Here’s a comprehensive list of must-have items:
| Basic Equipment | Safety Gear | Additional Items |

Remember, the specific tools you’ll need may vary depending on the site and the type of material you’re collecting. I learned this lesson the hard way when I showed up at a thunder egg site with only a small rock hammer – definitely not sufficient for the task!
Top 10 Rockhounding Sites in Oregon
1. Richardson’s Ranch (Madras)
Located just outside Madras, Richardson’s Ranch is legendary among rockhounds for its exceptional thunder eggs. I’ll never forget my first visit here – the excitement of cracking open a thunder egg to reveal stunning agate patterns inside. The ranch charges a reasonable fee for collecting, and they provide basic tools and guidance.

- Difficulty level: Beginner-friendly
- Fee: Yes (varies by activity)
2. Polka Dot Mine (Hampton Butte)
The Polka Dot Mine area is famous for its green petrified wood. The site is relatively remote, but the rewards are worth the journey. During my last visit in spring, the colors in the petrified wood were absolutely spectacular after a light rain.

This vast area offers multiple collecting sites for different materials. The Prineville District is particularly notable for its thundereggs, limb casts, and jasper. Personal tip: Visit the Prineville District BLM office first for detailed maps and current conditions.

A premier location for obsidian collecting, Glass Buttes offers several varieties including mahogany, rainbow, and gold sheen obsidian. Located in Lake County, this site requires careful navigation and a high-clearance vehicle.

Oregon’s state gem can be found here! The Sunstone Public Collection Area near Plush offers a unique opportunity to find these beautiful feldspars. I recommend bringing a screen and shovel – my most successful finds came from screening material.

Known for its distinctive green petrified wood, this area requires some hiking but offers remarkable specimens. Bring sturdy tools and plenty of water.
7. McDermitt Caldera
This site spans the Oregon-Nevada border and is famous for its pink plume agate. Access can be challenging, but the unique specimens make it worthwhile.
8. Fossil
The town of Fossil and its surrounding areas offer excellent opportunities for finding plant fossils. The high school in Fossil even has a public dig site!

While not traditional rockhounding, the cave formations here are spectacular. Note that special permits may be required for certain areas.

This area near Sweet Home is excellent for finding quartz crystals and gold panning. The creek-side location makes it perfect for summer collecting.
