Burma Road - Greenwater

Because today was the first nice day we've had when I was scheduled off, I decided to head up Burma Road on the Hancock Tree Farm land. I've had written directions to many collecting sites up there, but haven't been able to get to them because of the snow. I was hoping that I could get up a little higher today because of the recent warmer temps.


The gate to the Tree Farm was open, so I headed on in and followed my written instructions and drove 7+ miles up the main road. There, I came to an intersection which was not marked. Well, it was, but the sign was laying on the ground. I decided to continue on the main road for a while, to see if I ran across another sign, but I didn't, so I turned around and headed back to the intersection. I stopped and noticed the sign on the ground, and sure enough, it was the road I was looking for. 


I drove the 1+ miles to an unmarked 3 road intersection and reread my directions. They told me that small thundereggs would be in a mudslide area on the left side of the road. I backtracked and noticed a muddy area along the road, where rocks were eroding out, so I found a place to pull off and got out to investigate. 

Mudslide Area on Raod 6110

Right away I started finding thundereggs, jasper, and seam agate. The thundereggs were fist sized which surprised me, since my directions said they would only be 3".  They were very pretty being red, black and brown with bright blue colored veins running through them. I discovered that the best specimens were located in a dark black area of the hill. While I searched the slide area, Bandito ran around, chasing birds and sniffing out interesting scents. 

Darker Areas in Side of Hill

Because the area was wet and had standing water nearby, I was eventually chased off by the many no-see-ums in the area. I ended up with about 10 lbs of nice looking agate.

A Few of the Larger Thundereggs

I decided to head on to the next site and try my luck. Unfortunately, my directions were not that clear. They told me to head .1 mile further down the road and turn left. There was no road going left .1 mile down the road. The only thing close was the unmarked 3 road intersection. I decided to head for the next site on my list.

I headed back to the previous intersection and was to drive 2+ miles further down the main road. It said to enjoy the view at the 2 mile mark which I did. But I couldn't make it any further because I ran into snow on the road. So I turned around and headed back down the thunderegg road.

The Viewpoint with Mt Rainier Behind the Clouds

Again at the 3 road intersection I drove straight for a while and it soon became obvious this wasn't a main road, because it got so bad. So, I turned around and went back to the intersection again. Coming from the opposite direction, I noticed that the road on my immediate left seemed to be a major road and was heading in the basic direction I knew the road should be heading. I also noticed that the other road to my immediate left was a dead end and that a car was parked down there. That was a good sign, because maybe they were rock hunting. I decided to head down the dead end road.

As I headed down the hill, I realized that the rocks on the road were very big, placed for logging trucks, and prayed I wouldn't hurt my car or tires. I was also slipping and bouncing around a lot. I put it in low gear and just kept going. A little ways down, I noticed either a landslide or an area of digging on the side of the road, but because there was no turn around, I kept going. Because the road unnerved me, I turned around as soon as I found a good spot and decided to head home. The climb back up the road went better than I expected and when I drew even with the landslide area, I stopped and got out to check it out. Boy am I glad I did! 

I hit the geode jackpot! Everywhere I looked there were crystals shining up at me with various colored agate linings. Someone had dug a deep hole, but it looked like the geodes were scattered everywhere in the rocks.

Geode Jackpot!

Once again, I noticed these crumbly shining black rocks everywhere and the geodes seemed to be eroding out of the dark areas. I picked up round nodules, large amethyst crystals and large greenish colored rocks that appeared to be full of crystal and agate. It was a rock hounds' paradise.

Agates and Geodes and Crystals Oh My!

I picked up about 10lbs of nice crystals and decided I had better head back down or someone might start worrying about me. I know that there will be plenty left at this spot, since it appears to be a new find due to the recent logging road cut. One of the best pieces I found was a large piece of amethyst crystals just laying near the road.

I'm already counting the days until I can go back, start digging and find some large geodes! There are probably lots more down below!

NFMS Rockhound Rendezvous 2011 - Hampton Butte, OR

Well, it was a unique experience for me to attend the NFMS rockhound rendezvous last weekend over the Memorial Day holiday. Being new to this rockhound club group thing was both interesting, fun and educational. The only other thing I can say is that the weather was absolutely horrible.

We arrived at the group camping site on Camp Creek Rd. around 7:00pm on Thursday. As we were attempting to set up our tent, the rains started and we rushed to get it up. As soon as we had it up, the wind started in and I had to literally use all my weight to keep it standing while we secured it with extra heavy duty rope and stakes. This was to be an early indication of the entire weekend. That night it was so cold we pulled out all the extra blankets and coats and whatever else we could find to keep warm.

NFMS Camp Site - Central OR

I had signed up for the Hampton Butte field trip for Friday and as it turned out that was a good plan because no other field trips made it there afterward due to the foot of snow that fell down there Saturday morning. The entire area had become a wind-whipped frozen tundra overnight.

When we arrived at the Hampton Butte collecting site everyone went in various directions to seek out the beautiful petrified wood of this area. We weren't sure what to do, so we just searched around for chips laying on the ground and whatever else we could find. We stopped by one man who had dug a hole about 3 feet deep and asked if he had found anything. He said, no, but he was told that the good stuff was about two feet down. We decided that we weren't just going to start digging without any other information and continued scouring the area. We did find some beautiful pieces.

Hampton Butte Collecting Area

After eating lunch we headed back to the parking area and ran across an old-timer digging patiently in the many mounds scattered around and he was extremely helpful in showing us how to determine where to dig and how to determine the size of what you are digging for with the use of a probe (unfortunately we had left ours at home). One woman had dug up a reddish colored petrified log across the road. It was really nice. We decided to call it quits and head to Prineville for something to probe with and come back later. Of course the weather made it impossible to come back. We didn't know that then.

Road to Hampton Butte Saturday Morning

That evening I signed us up for the Congleton Hollow (Paulina) area collecting trip. This was a good move because on Saturday morning we woke up to snow showers and bad roads. Hampton Butte was not reachable. Our trip to the Congleton area brought us up dry roads and supplied us with many nice little pieces of pale green limb casts and agates. We did not dig as we should have. Our trip leader found two large limbs of beautiful agatized wood after spotting what looked like a small buried piece of wood. We did not see any exposed wood to dig for. Maybe we should have dug anywhere. Others in the group that stopped down by the creek bed found quite a few nice pieces after digging in the sides of the creek.

After lunch we headed down from the top of the hill to the creek bed and there we found lots of river polished agates that everyone else passed up to dig for the "big stuff." We were happy. I  even found an eight inch chunk of petrified wood sticking out of the creek bed where someone else had dug. Most of the day was beautiful and sunny with occasional clouds moving through, but around 4:00pm it clouded up and started hailing. We headed back to camp and warmed up our homemade chile for the potluck. It was raining so hard and the wind blowing that we ate some of the chile because we didn't know if the potluck would happen. It finally did take place during a brief clearing of the weather. Lots of food, many beautiful finds. One couple found two complete large agatized tree trunks that looked like the Arizona Petrified Forest wood up Camp Creek. Several others had found beautiful petrified limbs at Congleton.

Saturday Sunset - Camp Site Area

Saturday evening was so cold and windy that we decided to head for bed early and pray for better weather. We went to bed around 8:00pm just to get warm.

Sunday morning dawned cold, cold, cold and windy, windy, windy. We decided at that point that we'd had "enough fun" and packed up our camp. A field trip for the group to Glass Butte wasn't planned until Monday, so we decided to stop by there on our way home to check it out since I had a map to the area that I had obtained from my rockhound club (Puyallup Valley Gem and Mineral Club).

Glass Butte, OR

Glass Butte was beautiful! We were worried we wouldn't make it up the really muddy road to the main site, but our Escape slogged through fine. The road was very muddy and rough. I had a hand drawn map of the area and the different types of obsidian to be found there but we just pulled off the road and started hunting. It was laying everywhere! My husband decided to start digging and he dug up many large boulders. He didn't want to crack them because they shattered so easily (no duh!) so we just piled them all in bags and carried them home. Most of what we got was the banded and mahogany, but one piece I picked up shone gold in the brief 10 seconds the sun came out on our way home. Who knows what all we got. All in all I would highly recommend visiting this spot just for the fact of the abundance of this neat stone.

Some of our Obsidian finds

Despite leaving two days early and braving the freezing tundra of Central Oregon, we still had a wonderful time and plan to revisit this area in the near future, hopefully during better weather conditions. For more information on this wonderful area, visit the USFS website.
