    Kobuk Valley National Park is one of the least visited National Parks in the United States. Yet, it is still quite spectacular and geologically interesting.
    Also, tomorrow's video will cover the Tanaga and Takawangha volcanoes due to new information and the fact that their alert levels were BOTH raised from yellow to orange on March 9th 2023.
    Correction: at 2:17 in this video I mistakenly displayed “1/256” when I meant to show “1/16 of a mm”

      Any chance you could do a video on Crater Lake in Northern California? We stumbled on it when we were in the area and couldn’t find much information on it or it’s eruptive history from searching online. Pretty cool little volcanic lake though

      @@theandrew1375 , you mean clear lake volcano? Crater Lake is in Oregon. Clear Lake is a fascinating volcano and surprised a lot of volcanologist, it has one of the largest bodies of melt or mush zones of volcanoes in US other than Yellowstone or Long Valley volcano. It's had some pretty good sized eruptions in its past, VEI 5+ and certainly is capable of eruption in future. Very beautiful area of California. You have to search for scientific papers on clear lake to get decent info.

      @@GeologyHubI’m not sure the name of the mountain, it’s in Lassen National Forest I know. It’s got like a 28 acre lake inside a cindercone with a small campground beside it, and allows non motorized boats and fishing. We were driving through the area and saw a sign, decided to make the detour. The road was almost impassable in our rental car at the time, but it was really cool when we got there. It helped that we hadn’t made it to the more famous Crater Lake at that time yet, since the Oregon one is so breathtaking.

      @myaimistrashgaming5175 Рік тому +11

      From the US national park service -“The dunes were formed by the right combinations of wind, water, and sediment. Creeks and streams brought in large amounts of sediment and sand into the valley. Wind then blew the sand toward the bend in the Sangre de Cristo Mountains, where opposing storm winds helped squeeze the sand into the tall dunes you see today.”

    • @michaeldeierhoi4096
      @michaeldeierhoi4096 Рік тому +1

      No, very different. The Sahara desert used to be a more fertile region, but the process of plate tectonics gradually changed the climate of what would later become the Sahara. Part of the region was also under water as part of the Tethys Sea 7 million years ago. When the African continent began to collide with Asia the Tethys Sea shrank to become the Mediterranean Sea. This led the northern part of Africa to become more arid and like a desert. There is more to this story, but that is the general outline.
