Thunderegg Hunting in Oregon
…If you share the same interest or just want to talk rock,feel free to email me and I’m more than happy to chat. Or if you happen to travel through my part of Oregon, be sure to swing in and say Hello…
THE PACIFIC NORTHWEST HAS ALWAYS BEEN RICH IN A DIVERSE SELECTION OF MINERALS, ROCKS, GEMSTONES, A ROCKHOUNDER’S HEAVEN!!! OREGON HAS ONE OF THE LARGEST JASPER AND AGATE DEPOSITS IN THE UNITED STATES.
THE OVERALL OBJECTIVE OF THIS PAGE IS TO PAY TRIBUTE TO THE PEOPLE WHO DISCOVERED THESE DEPOSITS, THE MINER’S WHO STILL MINE IT, AND TO PROVIDE INFORMATION FOR ROCKHOUNDERS ON THEIR ROCKHOUNDING ENDEAVORS.
THE OCHOCO MOUNTAIN RANGE IN CENTRAL OREGON IS RICH WITH JASPERS/AGATES/OPALS, JUST TO NAME A FEW…..
THERE EXIST IN THOSE MOUNTAINS A VAST VARIETY OF THUNDEREGGS, “OREGON’S STATE ROCK”…FROM AGATE EGGS TO OPAL EGGS THE OCHOCO’S HAVE IT ALL. I RECALL AS A ROCK-PUP GOING TO THE OCHOCOS WITH MY DAD, WE WOULD ALWAYS COME HOME WITH A NICE SELECTION OF EGGS, PETRIFIED WOOD, JASPERS. THE MOUNTAINS THERE ARE TEEMING WITH LAPIDARY ROCKS…
A thunderegg is a type of rock similar to a geode but formed in a rhyolitic lava flow and found only in areas of volcanic activity. Thundereggs are rough spheres, most about as big as a baseball. They look uninteresting on the outside, but slicing them in half may reveal highly attractive patterns and colors valuable in jewelry.
Two stories on how they got their name:
1-Incidentally, the word, “thunderegg,” which includes both nodules and geodes, appears to have first been used by the Indians of central Oregon. It is said that they believed that Thunder Spirits living in volcanoes sometimes fought battles in which they hurled thunder, lightning, and stone “eggs” at each other. Perhaps those Indians knew what they were talking about, because parts of Oregon also offer spectacular geodes and nodules!
2-According to native legend, the Thunder Spirits lived at the highest reaches of Mount Hood and Mount Jefferson, and when they became angry at each other, they threw these spherical rocks at each other.
They are the state rock of the American state of Oregon.
The Hauser Geode Beds
By Delmer G. Ross
Professor of History, La Sierra University
The dull thud of picks, the crunch-swish of shovels, the tink-plink of rock hammers, and the occasional delighted, “I found a nice one!” all help to mark the location of the Hauser Geode Beds on an early spring weekend. Hundreds of holes dug into light-greenish colored volcanic ash under a nearly cloudless blue sky confirm it. Sometimes dozens of rockhounds may be found digging for geodes at this desolate appearing region of northeastern Imperial County, in southern California.
The geode beds are named for Joel F. Hauser, who discovered them with the help of his very observant father in the early 1930s. Twenty-five years earlier, the elder Hauser, George, had been a partner in Hauser & Giddings, a Colorado Desert freight line operating mainly between the Southern Pacific Railroad at Glamis, and the Palo Verde Valley town of Blythe. As he slowly drove heavy, freight-laden wagons across the desert, he followed two basic routes.
The preferred route led through Palo Verde Canyon. It was the shorter, more direct route. It was also subject to flooding and washouts, especially during the usual late summer monsoons.
The alternate route, used mainly when flooding in the canyon closed the canyon road, led from the little community of Palo Verde, near the Colorado River, west to the southern stretch of the Mule Mountains. After crossing over a low pass in the Mules located only a mile or so east of the present-day Coon Hollow Campground, it continued west, through what today is known as Ashley Flats, to another low pass some eight road miles away, near today’s Potato Patch. Then, turning southward for a mile or two, then southeastward, it eventually rejoined the main Blythe-Glamis road.
I bumped into Stephan and asked him if he would let me put his adventure on my blog. Here it is…enjoy !!!
Vacation on the Humboldt Coast, August 2011
This year, for our vacation, my son, Justin, and I decided to explore a portion of the Humboldt Coast. The siren songs of Agate Beach and Trinidad Beach jasper have been in our ears for some time now. Additionally, a dear friend and fellow photographer has been extolling Trinidad’s virtues ever since I have mentioned a desire to visit. Her pictures of the area certainly piqued my interest further….
For my pictures, please see:
Justin returned from his mother’s house at 8:30 AM. I finished packing the car, and we (including Buddy and Buster, the wonder-wieners) were on the road by 10:15. Heading north in I-5, we were filled with excitement. In spite of the mild summer we have been experiencing in Davis, the air was hazy, and it became quickly evident that the northern valley (which does not receive the cooling Delta Breeze that we do) has not enjoyed this to the same extent. Within an hour from home, the temperatures were in the mid-90s (Davis had a forecast high of 88°F for that day), and the Coast Range, quite close to the freeway, was not clearly visible. The Sutter Buttes, also, were only visible in silhouette. When we reached Redding at 12:30, it was a sweltering 99°F, and the only thing I could see of Mount Shasta was a fuzzy outline of its snow-capped peak.
We turned west into the Trinity Alps. The three hour drive through the mountains on highway 299 was gorgeous and surprisingly hot. The temperatures hovered in the mid-to-high 90s until we were within about 10 miles of Arcata, at which point they dropped rapidly.
For lunch we stopped at Bagdad, on the Trinity River. I wanted to do a quick search for jade, but the area was designed for boat access of the river. Reaching the rocks would have required a swim.
All along the drive I saw numerous possibilities for future camping trips along the Trinity River (jade hunting kayak-trips, perhaps?). I imagine near Willow Creek will be the place, as it closer to the coast and somewhat cooler.
We arrived at about 5PM and set up camp. The campsite was nice: large and relatively private, secluded in ferns and bishop pines.
After set-up, we took a quick trek to Agate Beach (about a mile from our campsite), and found some goodies – mostly jasper.
I woke up at about 6:00, mainly to the sounds of crows, ravens, Stellar’s jays, spotted owls and woodpeckers as well as a few unidentified birds. There were very few human sounds. The noisy revelers were still asleep and the early risers respected the quiet. I stayed in my sleeping bag, listening, until about 7:00, and then got up for breakfast. I realized then that I’d forgotten to bring my coffee (d’oh!), but green tea was just fine.
At 9:00, Justin woke, and had his breakfast. Afterward, we proceeded to Sumeg Village (a model Yurok village), where a program was put on by local Yuroks. A tour of the village was performed by Skip: a Yurok as well a Park Ranger, which provided an interesting perspective (and one that was more accurate than the usual anthropological approach, I imagine). We learned, for instance that Yurok houses have small round door designed to keep bears out. Yurok tools were chiefly constructed of elk horn, rather than stone. Also, since Yuroks consider all things alive and imbued with spirit, represent physical features in things they build. For instance, every Yurok canoe has structures representing a nose, heart, lungs and kidneys – the essential organs.
Following the tour, we were treated to Yurok songs and prayers to prepare us for a salmon feast. The salmon was delicious, slowly spit-roasted over a redwood charcoal pit. I even partook of what is considered a delicacy – the head, which was moist and quite delicious, particularly the cheek meat.
Well-fortified after lunch, Justin and I biked into Trinidad, about 5 miles away. This turned out to be slightly more challenging than I imagined. Although Justin and I are both avid bikers, I did not have my regular bike – a cargo bike is too large for my roof rack. Instead, I was riding Justin’s “spare” bike, which even at its tallest setting is too small for me. Unlike Davis, Trinidad actually has hills, which are quite tough to bike when your knees are nearly smacking you in the chin.
Upon returning, we headed to Agate Beach for our first serious agate hunt. We hit a beach packed with agate hunters, over half of whom were armed with “agate scoops” – essentially three-foot-long slotted spoons. Most of these were identical and presumably purchased. A few, though, were creatively home-made: one was constructed of a golf club handle and a small kitchen sieve, another of a wooden dowel and a kitty litter scoop. These folks had a distinct advantage as they were able to reach agates that were further away without diving for them. Most of these folks also seemed focused only on agates. Many had pint-sized Ziploc bags significantly filled with agates.
I, on the other hand, found two agates. This is probably due to several factors. I do not seem to have “the eye.” Many of the hunters have been coming here for years and know what to look for, and take only agates. I, on the other hand, was distracted by the amazing array of jasper and jade that can also be found (in fact, they are more plentiful than agates). Also, without a scoop, I simply could not reach many of the agates that I did spot, since they do not remain in one place for long before the next wave moves them again.
Speaking of jasper, I found one piece of classic brecciated tan and pink Trinidad jasper with a gorgeous seam of agate running through it. More common are pieces with brown or tan landscapes and blue sky in colors reminiscent of Rocky Butte jasper from Oregon.
At Justin’s insistence, I woke him up early for some just-past-sunrise, low-tide “agateering.” The beach already sported the hard-core hunters. As we searched, I chatted with a few of these old-timers. One was a San Francisco man who has been coming with his family every year for 40 years. Amazingly, he was not aware that there is also an Agate Beach in Bolinas. In any case, he shared some of his hints: the area where the water is an inch or two deep is best. The agates are briefly still, and give off a blue “glow.” This did not help me greatly, as every blue glow I saw was either 20 feet away, in someone’s scoop, or a “false positive” – grey chert. I again found jasper and jade more frequently than agate (once again, I found two agates, which were slightly larger than the previous day’s finds).
By about 10:00, the morning fog had almost completely burned away making all the stones on the beach sparkle in a very distracting manner. Nevertheless, after lunch, Justin and I joined a ranger-led hunt. Her presentation confirmed my suspicions about two brown stones I had found in the morning – they are petrified wood. During this hunt I actually found three agates (!), two more pieces of petrified wood (okay, auto complete just tried to turn that into petrified woodpeckers, which would be an extremely cool find), and a fairly large black piece of whalebone (a piece of rib, perhaps?). Justin found several agates and an egg-shaped piece of Trinidad jasper that makes me drool (see the pictures link to see it).
That night, our campfire was slightly less relaxing than usual since we had some new neighbors: one family began arguing the moment they pulled in, another had three small squalling children that went on shrieking for hours…
Monday morning dawned perfectly clear. Justin once again slept in. After a short morning agate hunt (I again found two), we opted for a road-trip to Fern Canyon. On the way, we stopped for pictures of one of the local herds of Roosevelt elk. They were amazing to see, but at about half a mile distant, so I don’t think we got a full appreciation of how huge these beautiful critters are. Getting to Fern Canyon involved driving along eight miles of bumpy and dusty, but decently graded, dirt road and making four water crossings. The ranger assured me that my car (not a four-wheel drive) could make it, but the first one made me a bit nervous. Luckily the crossing contained sufficient gravel that tires did not sink into mud.
The short hike (no dogs allowed) at Fern Canyon (where parts of the Jurassic Park movies were filmed) was totally worth the bouncy drive. We first crossed a meadow with a very clear creek, tall bushy horsetails, prolific wild-flowers and dozens of dragonflies (black saddlebags, I’m fairly sure) that absolutely refused to land and pose for pictures. The canyon itself is only half a mile long: a deep trench lined with four different species of ferns (so that’s how it got its name) and waterfalls. Downed logs were decorated with mosses and unusual fungi, including one growing a red, brain-shaped jelly fungus of some sort. At the end of the canyon Justin and I opted for the loop hike ascending what one kid described as the “endless stairs” for a small wood-land like. We crossed another meadow with numerous dragonflies (some sort of darner this time, I believe), which were equally camera-shy. This is a perfect flip-flop hike: wet and not at all difficult.
After this hike, we decided to head to Big Lagoon, a dog-friendly beach. One of the Patrick’s Point rangers had told us that nearly every beach in Humboldt County, with the exception of Agate Beach is dog-friendly. She had also told that many local search for agates there when it isn’t sandy, since there are fewer people. It was sandy. A sign sported a very amusing typo in reference to dogs (see pictures).
The beach excursion did not last long, since the dogs were being brats, escaping their harnesses repeatedly. Justin and I opted for a hike at the camp-ground instead. We toured the Yurok ceremonial rock, and then explored Mussel Rock, Lookout Rock and the Wedding Rock.
At night the kids across the way cried and screamed for three hours. Lovely.
Another early-morning agate expedition. It started off foggy, but by 9:00 the fog was down to thin wisps. This was apparently good for Justin’s “agate-eye,” as he found a good 20 pieces, including two that resemble faces. I found four agates, but struck an absolute jade-jackpot. I talked with an old-timer couple, who, like me, had a more eclectic focus, also pursuing jade and jasper. The man told me that the blue and brown Oregon-jasper-like pieces I had been finding could often be cut to reveal black agate in thunderegg-like formations. I will have to try it.
After brunch, Justin participated in a Junior Ranger “slug slam” program where we learned that slugs breathe through a hole in the side of their heads, and we also made artificial “slug-slime” – yellow oobleck.
Next on the agenda was a trip to Trinidad. We arrived to perfectly clear weather and headed to the lighthouse overlooking the bay. I have to say that this is one of the most spectacular views I have ever seen. This place seriously gives Kauai a run for its money in terms of sheer, breath-taking scenic beauty. I vowed on the spot that we will return next year. Since the dogs had been brats on the beach the day before, we decided that they would not be going to the beach today. To make up for this, we took them for a nice hike of Trinidad Head. This was a long enough hike to tire them out (Buddy, the 14 year-old, had to be carried for the last bit). The views were stunning, and I saw many wildflowers with which I am not familiar
The next item on the agenda was exploring Trinidad State Beach which contains spectacular boulders of multicolored jasper with tafoni-like features, caves and off-shore sea-stacks, one of which is 10 acres in size and covered in bishop pine. The beach also contains a creek that is the source of Trinidad Beach jasper. I managed to find three pieces. Two look promising, but one revealed many fractures after I cleaned the creek-slime. No worries. We will return here! When I know whether I picked well, I can get more. I also lugged a few 30-pound landscape boulders through a half mile of deep sand. A very good work-out.
Our last full day dawned to weather that is more typical than what we had been experiencing: heavy fog. Our last agate hunt lasted only about two hours. The fog wasn’t burning off, and Justin was thoroughly chilled. During our time there, I did have the time to speak to an old-timer, who claimed that agates are getting more rare with more people coming. He claimed that it used to be possible to find 100 – 150 agates in an hour, and that he is lucky to find 20 or 30 a day now.
After warming the boy up with oatmeal and green tea, we decided that an inland hike of the big trees would be in order. Once 101 turned inland after Orick, it soon became sunny.
Parking at Big Trees, we found a nice, shady spot for “the boys,” since dogs are not allowed on the trails. We picked a nice 6-mile hike off the map and got going. Evidently this map marked trails “as the crow flies,” since it did not show switch-backs, which expanded the hike to at least 10 miles and made it moderately strenuous. It was Justin’s first exposure to totally wild, dense vegetation, and he became convinced that we were lost, and was visibly relieved with every trail-marking sign.
This hike earned us a substantial dinner, so we headed to eat at the Trinidad Eatery and Gallery, which had been recommended by a friend (the same friend who raved about Trinidad itself). Justin and I shared a plate of calamari for the appetizer, followed by clam chowder for him and an excellent cioppino for me. For dessert we split some dynamite blackberry cobbler.
Justin fell asleep by 8:30, and I read by the campfire. The screaming, sobbing kids were gone!
Homeward-bound. The last day of vacation is always a melancholy event. I am usually blissful from the experience, but sad to be leaving. This time was no exception. After one last hike of the campground trails, Justin and I packed and headed out, opting for the highway 101 to 20 route, to make the trip a loop. Just like 299, this is a beautiful drive, though much of it seems studded with tourist traps (Bigfoot themed and redwood themed). I saw many possibilities for future explorations of the area, and also managed to lose count of the number of times we crossed the Eel river (Justin insists it was 29).
Much of this drive was quite a bit cooler than the trip in, until we neared Laytonville, and from there until past Clear Lake and Williams, temperatures hovered near 100°F. As we drove south on I-5, it cooled very gradually until we hit Woodland, which is apparently as far as the Delta Breeze reaches.
Justin’s favorite hot-and-sour soup welcomed us back to town. Everyone (including the dogs) took a thorough shower and relaxed in our own beds.
The dogs are still sleeping as of Sunday….
I am very grateful for this experience.

Since I travel a lot I and I find myself seeking this kind of knowledge, I thought I would make a new category for rockhounding vacations / travel. As well if you have a special place you like to stay and rockhound please email me and I will post firstname.lastname@example.org. Pictures are appreciated as well.
Rockhound State Park and Spring Canyon Recreation Area
Established in 1966, Rockhound State Park consists of the main park and the Spring Canyon Recreation Area. The main park includes a 30-site campground, hiking trails and a visitor center on the west slopes of the Little Florida Mountains. The Spring Canyon Recreation Area is a day-use area located across the valley in the foothills of the Florida Mountains and includes picnic sites and hiking trails.
Take a Hike
The park’s Thunderegg Trail (1.1 miles) and the Jasper Trail (.5 miles) provide access to spectacular wildflower displays in spring, mild autumn weather, and scenic views year-round. Scattered along the trails and throughout the park are assorted volcanic rocks and silica minerals including quartz, chalcedony, agate, and common opal.
Every April, Rockhound State Park hosts Desert Alive!, a springtime celebration of the Chihuahuan Desert and the rocks, plants and animals found here. Join nature walks, take in displays and exhibits and learn all about natural and cultural history of this special place.
To get to Rockhound State Park from Deming, take N.M. 11 south for five miles, and then go east on N.M. 141 for about nine miles.
Rockhound State Park lies in the Little Florida Mountains southeast of Deming, New Mexico (Fig. 1). It was established in 1966 as the first park in the United States that allowed collecting of rocks and minerals for personal use. Each visitor is allowed to collect as much as 15 lb of rocks and minerals from the 1,100-acre park; mineral dealers are not allowed to collect for sale. Rockhound State Park actually consists of two separate units, the main park and Spring Canyon Recreation Area (Fig. 1). Spring Canyon lies in the northern Florida Mountains, south of the main park, and is open for day use only from Easter through November.
The main park provides excellent views of the surrounding mountain desert. Basin and Range topography is easily seen in the distance. On a clear day the smokestacks of the Hurley smelter can be seen to the northwest. The Cobre Mountains form the far northern horizon behind the smokestacks. The Burro Mountains lie to the west-northwest; the Victorio Mountains lie to the west-southwest. The Florida Mountains lie directly to the south of the main state park; Florida Gap separates the two ranges. The Cedar Mountains lie to the south-southwest. The dark mountain north of Deming is called Black Mountain. Spring Canyon in the Florida Mountains is a sheltered canyon and offers solitude common to many canyons throughout the desert Southwest.
The Florida and Little Florida Mountains are typical of the mountain desert throughout southern New Mexico and Arizona. Elevations range from 4,400 ft along the foothills, where the state park is located, to 7,448 ft at Florida Peak in the Florida Mountains. Water is scarce and limited to wells and hidden springs, but be careful of thunderstorms and flash floods during the summer months! Despite the dry, seemingly inhospitable environment, life abounds. The area is home to many lizards and snakes, deer, antelope, coyotes, and small mammals such as prairie dogs, rabbits, badgers, and many birds. Mountain lion and desert bighorn sheep may be seen at the higher elevations of the Florida Mountains. A variety of plants thrive in this environment, including yucca, prickly pear cactus, barrel cactus, ocotillo, creosote bush, mesquite, and hackberry; juniper and scrub oak are common in the canyons.
Paleozoic through lower Tertiary sedimentary rocks overlie a Cambrian granitic to syenitic pluton in the northern Florida Mountains (Clemons and
