- This brief video is about the unusual building stones that create the exterior walls of the Ft. Jones Museum, Ft. Jones, California. The Ft. Jones Museum, is architecturally unique by its construction materials. It is indeed shocking to see it for the first time. The construction philosophy seemed to favor using as much variety of different rock types for building stones as possible. This is different than standard stone construction. The reason for this choice was to feature the various rock and mineral resources in the Siskiyou County area (and Northern California). Some of the stones in the wall are obviously imported, such as the grist stones from France, and the grinding stone from Ohio. However, these were used locally. However, I believe that some other stones in the museum walls originate from far outside the county too.
It is delightful to see the variety of rocks in the walls of this building. It is creative, humorous, and in many way geologically and architecturally impractical to use some of these rock types in construction. But this notable building is delightfully successful architecturally, for achieving its goal to featuring both local and mining history. It is an amazing place. I have seen some weird building stones. But this building uses a huge variety of rock types.
Hello Rock People! This is Dave the Geology Dude. Please be aware that the only way to really learn rock identification, is to have hands-on experience. This is because visual experiences alone do not show properties like hardness, acid reactivity, density, and the range of variables that are common to each rock type. Note: if you don't like the music on this video, you can always turn off the sound and watch with your own music instead. Don't forget that Geology isn't Rocket Science--it's Rock Science!

Absolutely gorgeous! Also the quality of the shots are amazing Dave , great work as always Dave !
Thanks. I’m getting better at this, but it is often a struggle to use large-scale photogrammetry. Sharp focus often is a problem with photogrammetry. That is part of the reason I am initially doing many #shorts videos. #Shorts videos are vertical format generally for cell phones--so even a slightly blurry image looks okay in that format. But when everything works-it’s fantastic! And I am planning to scale up the #shorts videos I have done in the future (into longer videos).
Hello Rock People! This is Dave the Geology Dude! There is more to this video than just a spinning museum of rocks. There are detailed notes in the description area of this video. If you want more, longer length rock identification videos are on my CZcams homepage. Check them out, or leave a comment here!
The chemistry of all things interest me. How did you come to know elements? Oh, you are a geology dude. Sorry for the not so smart question.
No worries ! Of course I had to take chemistry classes to get my geology degree. I learned the elements there. However, once I learned the chemistry of the different minerals, I began to learn another level of how elements interact and can change things. Water causes many minerals to weather and rust-and to change into other minerals that are more stable (like pyrite rusting)…. Hot acidic water underground can dissolve many minerals, and then water can allow dissolved elements to migrate underground with the water-and later form into new types of minerals. This process seems quite fantastic at first, but the reactions are predictable and normal with chemistry. So knowing how elements react and change, allows geologists to look at the slight changes of minerals within rocks. Knowing these changes can direct predictions of where gold may be found underground (or other valuable minerals). So it is a powerful tool to know about elements and how they interact and behave.
Wow. I am so interesting now in food chemistry. You know, the things I put in my mouth... what's really in it. I had a biology class in high school, but there were not enough binoculars...hand when do you get your young in chemistry?
@@debbiehaythe102 Different color salts are popular today. Of course most are all 90%-98% salt, but the color allows more profit with higher prices to buy. Otherwise, it is just salt. Trace elements can give the salt different colors. For example, a pink salt in Wyoming (known as Himalayan salt) contains potassium, calcium, and magnesium. The original pink Himalayan salt has a slightly different composition of trace minerals. Some salts contain trace elements that are not good for you, so they are not sold for consumption. But to advertise that the trace elements in colored salts are so good for you-when the same elements can be obtained from a vitamin-seems rather ridiculous to me. Thx for the good comments!
I'd love to see you do a walkaround with Brent at Cerro Gordo. The history of the mine and the surrounding geology would be a fascinating video. czcams.com/users/GhostTownLiving
Hi Jacob! Yes! I’ve seen the videos on this channel and it is an interesting place! Thanks for mentioning it!
