White Rock Springs Thundereggs

White Rock Springs is one of a few thunderegg collecting sites located within the boundaries of the Ochoco National Forest at the southern edge of Mill Creek Wilderness. Digging is prohibited on wilderness land. There is a private mining claim of Mt. Hood Rock Club that can be accessed through club membership. This area is fenced off.

On the northern side of the road, you will find a few pits where you can start digging with a geological pick and shovel. The soil is relatively soft here.

Generally, most of the eggs found here tend to be small, ranging between 1 and 2 inches. Cores might be clear grayish agate, contain miniature quartz crystals or have completely crystal structure with purple or blue hues.

The White Rock Campground is within walking distance from the collecting area. This is a free first-come, first-served campground with picnic tables, fire pits, and a vault toilet. Wildcat South Trailhead at the northern edge of the campground provides access to the southeastern portion of Mill Creek Wilderness through Wildcat Trail (#833).

Check a map of Mill Creek Wilderness and trails.

Please keep this place clean, pack out all your trash.

A high-clearance vehicle with four-wheel drive is recommended for the final 1.3 miles.

Another public thunderegg collecting area White Fir Springs is located 2 miles away on your route to White Rock Springs.
