Dig for spectacular Turquoise! Another spot on the rockhound roadtrip…to the Otteson Brothers Turquoise Mine.

Just a quick drive into Nevada and a little detour off of I80, this stop is well worth your time!
Tours, paid digs, a wonderful gift shop, and tons of fun!

Our History
Our father, Lynn Otteson mined on and off in Colorado since he was a teenager, and leased his first mine - the Lick Skillet (Manassa King) mine from Pete King just a few miles east of his hometown in Sanford.

His first Nevada mine was a Royston Claim leased from Lee F. Hand in 1944, traveling back and forth from Colorado to mine it part-time. His dedication to his family and dreams were undeniable. One time Mom and Dad (with baby, David) caught a ride from Colorado to Ely, Nevada (about 160 miles north of Tonopah) then hitchhiked all the way from Ely to Tonopah. Another time Dad partnered with a man who had a vehicle to mine the claim. When they had mined a big enough load of Turquoise, his partner (who had the only vehicle amongst them) offered to take the Turquoise to the Gallup/Albuquerque areas to sell it and split the proceeds. Unfortunately, his partner never returned with the Turquoise – Dad’s share of the proceeds which would have provided food and water for the family – and left them (Mom, Dad and baby David) stranded at the Royston mine without a vehicle. Dad had to walk 25 miles into town to ask for help. Years later, Dad told us that he ran across his “ex-partner” years after the incident and “got even.” Just how he got even – we’ll never know.

In the summer of 1960, Dad’s dream finally became a reality when he moved the family from Colorado to Tonopah, Nevada – and our family has mined claims here ever since.

Lee F. Hand – a well-known Nevada Turquoise Miner – discovered Royston Turquoise in 1902 and controlled over 30 claims in the Royston District of Nevada – originally consisting of four old Turquoise Claims: Bunker Hill, Easter Blue (8-10 miles to the north), Oscar Wehrend and Royal Blue. This district includes some of the oldest and most active mines in Nevada.

Today, the Royston District is primarily controlled by the Otteson family – who has mined numerous claims within the district on and off through the decades – frequently partnering with friends and members of our family. We continue to prospect for turquoise as our Dad once did, and we’ll continue to add these claims to our growing list of the Otteson family owned and operated mines.

For three generations, we have proudly mined and processed some of the most sought-after high quality natural turquoise on the market today.

While we are on the California coast, let’s head down to Cambria, not only the home of Hearst Castle but also a destination with some outstanding rockhounding! Welcome to Moonstone beach!

The stones on the beach are not actual moonstones, which are a type of opalescent feldspar, but are instead chalcedony, quartz, jade, jasper, agates, and more. The name likely came from the shape and texture of the rocks, worn by the tumbling waves into smooth, round treasures. The rocks are so polished that you can walk on them without shoes or sit down on the beach and sort through the colors, shapes, and patterns to select your favorites. When they are wet you can see the rainbow of colors in the rocks. There are even a few pieces of frosty sea glass to find among the rocks, plus driftwood of all sizes tossed by the waves.

ROCKHOUND SPOTLIGHT!

Some of us find fantastic rocks and minerals and then display them as we found them, but some of us take our finds and create exquisite art with them. Angel Blanco is just one of those people! Check out these superb finds from his adventures in Oregon, and the delicate arrowheads he crafts!

In his own words…
“My favorite thing to do is find jasper I can turn into arrowheads, that basket of arrowheads is all from jasper I found and then turned into arrowheads”

Thanks Angel!

Are you close to Reno, NV? Want to hunt for colorful copper minerals? Take a quick road trip to the Cold Springs mining areas north of Reno and bring home some spectacular stuff!

We love Rollie’s adventures….here are some wonderfully colorful finds from a place that’s easily accessible, no upside down head-first caves for these 🙂

On the way home I decided to stop at Cold springs to collect some copper minerals
Chrysocolla, malachite, azurite, and various odds and ends minerals.
Recently a friend of mine had told me that they were not finding much anymore. So I got to my spot and started digging..
Ended up with about half a bucket full of some nice material. I sent photos to my friend, and he is headed there now lol! Here are a few pics of some of the better pieces. Some of this is gem grade and patterns run all through the pieces. About a foot deep you will start seeing the blue. Just inspect the rocks at they layer, and pieces of nice material will pop up. Good luck for those should go out and check it out. 😁

Heading down the coast we make a stop in Fort Bragg, a location famous for its rugged beaches, world class ocean fishing, abalone shell collecting, and of course Glass Beach!

Although much of the glass and pottery has been pocketed by tourists over the last half century, there are still sections of a few coastal stretches where the beach is as much glass as it is sand.

In 1906, Fort Bragg residents established an official water dump site behind the Union Lumber Company onto what is now known as "Site 1". Most water-fronted communities had water dump sites discarding glass, appliances, and even vehicles. Locals referred to it as "The Dumps." Fires were often lit using Molotov cocktails to reduce the size of the trash pile.
When the original dump site filled up in 1943, the site was moved to what is now known as "Site 2", the active dump site from 1943 until 1949. When this beach became full in 1949, the dump was moved north to what is now known as "Glass Beach", which remained an active dump site until 1967.

We’re heading back here next week, great place to see the glass but also collect fossils, shells, and agates!
