BLUE FOREST OF GREEN RIVER: (Desert badlands/BLM) Farson is @77miles SW of Lander on Wy. Hwy 28. Beginning at Farson continue of WLY 28 to the SW for 21.3 miles to Sweetwater County Road 8. If you are coming from I 80, take Exit 83, west of Green River, to WY Hwy. 372, Drive 27 miles north of WY 372. Turn to the right onto WY 28 and drive 6.7 miles to CR 8. Travel north on this gravel road for
11.3 miles. After a long straight stretch you will climb a little rise for the last part of this section. Turn to the right on a worsening dirt road and mark your odometer. You will pass a small rock quarry to your left and some oil field-related turnouts that obviously terminate within sight. At the 2.7 mile mark on your
odometer turn to the right on a much narrower dirt road. Stay to the left for about the next 2 miles. This will wind around to a sort of flat top with piles of rock scattered throughout the brush. Find a place to pull safely off the roadway. The Blue Forest is probably the best known site among wood collectors. It covers quite a bit of area and has been worked extensively. For the most part the opalized wood is encased in a
type of algae. Discarded opal crusts that previous collectors separated from their prizes are easily found. A pick is helpful in breaking new ground but use it with caution and don't break good pieces.

PALM WOOD WEST OF OREGON BUTTES: (#39) (Desert/BLM) From Farson, take Wy Hwy 28 for 12 miles to the east toward Lander. If you are coming from Lander, the Tri-territorial Road will be about 65 miles SW on WY 28. Continue down the Tri-territorial Rd. for about 4 miles to the first intersection marked with a directional sign and find a place to park safely. There is wood virtually all over this area though most of it is concealed under the sandy soil. Walking along the dry washes provided some beautiful specimens of palm wood. At the next sign, 1.8 miles farther down the road at an intersection, there is another type of petrified wood. The road cut itself can offer some of the best opportunity, especially if it has been recently graded.

BIG SANDY ALGAE: (Desert Reservoir/BLM) Near above location. Go 2.3 miles east of Farson on Wy Hwy. 28 to the Bridger Wilderness Big Sandy entrance (Farson 4th west). Travel down this gravel road to
the second four-way intersection and turn to the left onto the Farson-Eden Reservoid Road, about 5 miles away. Go 2.3 miles on this gravel road and take the right hand roadway at the unmarked intersection.
Follow this improved dirt road 5.5 miles to the dam. Erosion leaves fossil algae exposed both on the shoreline and in the banks. Most pieces are large.

Palm Wood West of Oregon Buttes
From Farsen take Route 28 East for 12 miles to toward Lander. Take the Tri-Territorial Road for 4 miles to the first intersection. Found a beautiful limb with Blue Chalcedony and clear white Crystal in the center. Found a couple of pieces of Palm Wood.

Hi Joe,

It sounds like you have collected this area quite abit. Do you have any information on the Evanston area? Looks like I will be making a trip from Portland out to Evanston here in the very near future and would like to collect abit around Evanston.

Thanks Joe,

Bob M.
Hi Joe,
Sounds like you know your way around Wyoming. Have you ever came across any Manville Agates? Is there any public hunting areas around Manville? Thanks for your time and happy hunting.


Joe Dunleavy

No I never collected atound Evanston area. But ab ove 80 from Rock Springs is pretty good area.

I was searching the internet for information on the Blue Forest and Eden Valled Palm Beds for a "nostalgia" trip back into my past. In the late 1940's my dad became a rockhound and remained so until his passing. As a child I made many field trips with him and my mother to various sites across Wyoming. Eden Valley,the Palm Beds and the Blue Forest were some of his favorites back about 1950-1960. I can remember well stroling the shale hills. With my son now living in Rock Springs, we decided to see what we could find this weekend. We had no problem finding the Blue Forest and walked around it kicking at a few rocks for a while. We then drove over to find the Palm Beds following the directions from Graham's book Rockhounding Wyoming, and the four of your postings from 08/03/06 and May 2001 Wyoming Collecting on McRocks Forums. We found all three places mentioned along the Tri-Territorial Road, and found some wood at all three. We found three pieces of palm frond at the 4-mile site just stroling around. We found some recently excavated pits at the 5.8 mile posting. Some show but no specimines. Had trouble finding the 13 mile spot by the transmission line because we didn't have the printout. Didn't find anything there but we were about half a mile off. Found some small black specimines (chips) on the north side of the road at about 14 miles. No idea what they are.

What I'd really like to do is find the area my dad hunted palm in back about 1950. None of the spots we stopped at along the Tri-Territorial Road looked quite like what I recall in my memory. I'm guessing that he and others had another spot those many years ago. Does anyone have any other sites for palm wood in Eden Valley - a place called the "Palm Beds"?

There are lots of good spots along the Territorial road, the old timers use rakes to surface collect for petrified wood. Any cow paths or water ridges can bring good petrified wood. One of my pretiest little blue ones with tiny crystals was turned up by some cattle wondering around looking for a snack. I never had much luck back by the pwoer lines though, further out and back where you enter the road has been good to me.

The Blue Forrest usually takes a lot of heavy digging to get any of those big logs but there are usually plenty of smaller pieces. Around the oil rigs can be good also.

Thanks for your reply. My dad always packed a couple of 4-tigned garden cultivators. I can remember strolling the rounded tops of the shale hills raking as we walked. That's what I did on this trip. I really suspect that where he went was further on out. Time did not permit us to explore this time. I'll be back to Rock Springs and will likely spend more time out in the "valley". I have good rockhounding friends back in Colorado where I live who have been to the Blue Forest. It's likely that we'll do some sharing when I get home.
Hey I was wondering if you knew of any public places I could take my boys geode hunting?
Bob Harman
Kari, There are a few sites in Wyoming where you and the kids might find Western type thundereggs, but I am not sure of the specific sites out there. For fun and ease of collection with younger kids, I might try the fish fossil beds near the town of Kemmerer in the Green River formation. They have a fee for digging area that is always productive with nice fish fossils. CHEERS....BOB
