White Rock Springs Rockhounding

• White Rock Springs is a thunderegg rockhounding site
• Be aware, the area east of NF-3350 is under MHRC claim



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. If you want to find better materials in the area, make an arrangement with the Mt. Hood Rock Club.

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.

Mount Hood Rock Club Dispute

Our team received a request to remove the article because the posted coordinates is on the private Mt Hood Rock Club claim (see comments).

We contacted US Forest Service. According to them, the coordinate we provided here are on public land. The part of the USFS response and a map is bellow.

White Rocks Thundereggs

" I just spoke to our Law Enforcement Officer for USFS and he advised that I was correct. There are no restrictions, and that’s actually a plotted hot spot for our rockhounders on our rockhounding map. I attached a screenshot photo of where those coordinates plotted on my OnX Map, and it is Ochoco National Forest land- so if our LEO says you are good to go- you are officially good to go my friend and ENJOY! Just had a group come out with quite a few beautiful thundereggs from that area! I hope you have a fabulous time!"

  1. This is NOT correct. The coordinates you are posting are of the private Mt Hood Rock Club claim. The area past the barbed wire fence is a wilderness preserve where no digging is allowed. White Rock needs to be removed from your list or moved up to the actual White Rock camping area. This is the private TNT mine claim originally owned by Tim Fischer and now by MHRC and you are actively encouraging people to illegally claim jump which can get them arrested. If you want to go to this site, look into becoming a member. It is inexpensive but the membership fees help pay for the claim and maintenance of it.

    1. Coordinates were taking outside of the Mt.Hood Rock Club fence which was on the hill slope in 2018 near Forest Road 3350.
      Let me know if the fence was moved down to the road after 2018.

      1. There is no fence surrounding the MHRC claim. The barbed wire fence is the edge of the wilderness area where digging is not allowed. The GPS coordinates you have on here are probably from the Rockhounding Oregon book which was written years ago when there was a lapse in the claim ownership. Unfortunately the author never updated the locations when the newer edition came out. The claim is posted online and clearly shows that the claim covers the whole NF 350 road until the barbed wire gate. So nobody should be turning on NF 350 to dig anything unless they are members and report how much material they removed so it can be reported to BLM. It is also posted on the BLM site interactive map.

        Please either remove this listing or add a notice to not dig in this area as it is a private claim. The only public agate beds in this area are at White Fir (which is technically jasper). You are actively encouraging the general public to break the law.

      We contacted to US Forest Service. The GPS coordinate posted on this site is public land.

  2. Is the area accessible in mid-March, or is it covered in snow with the elevation this is at?

    1. Do not go there in March. The end of May depending of weather conditions is the earliest time. Contact Forest Service for updates.
