The Geology Behind the "Sailing Stones" of Death Valley
Death Valley's Racetrack Playa is the best known and most famous of the various places where "sailing stones", or moving rocks, leave tracks behind them on dry lake beds. This phenomena has been documented for nearly 100 years at the Racetrack, but it was not conclusively described until 2014! Various other researchers had postulated on the true cause prior to that, but the 2014 paper showed exactly the conditions required for the rocks to move.
The sailing stones are moved by sheets of very thin ice which form atop a temporary lake which sometimes occupies the playa's south end, where most of the rocks are. High winds blow these sheets of ice around, often eddying and spinning around, whi...

Devils Hole: Nevada's Window to the Aquifer
Просмотров 20 тыс.4 месяца назад
Devils Hole is a spring-fed pool in southern Nevada, and also a cave of unknown depth. This mysterious hole has been the site of diving accidents, scientific research, and political controversy due to its population of Devils Hole Pupfish, a tiny fish who's entire habitat is confined to the uppermost shelf of this cave. Geologically, it's a fissure dissolved out of the limestone by groundwater ...

    Although variable population mutation rates make it difficult to gauge, several recent genetic studies suggest that that the Devil's Hole pupfish only diverged in the last 1,000 years from the Amargosa Pupfish. My favorite theory is that they were originally brought to Devil's Hole by humans.

    • @BetterGeology
      @BetterGeology 4 месяца назад

      The main reason we can say that with certainty is that this old event was simply too small. The Cascadia Subduction Zone operates on its own conditions because it is so large, and smaller earthquakes like this are on unrelated systems (usually). Yellowstone's major eruptions are completely independent of any earthquake systems because it is fueled by a hotspot which derives its magma from the Earth's core. When Yellowstone is ready to go, we'll know years in advance, partly because it will trigger lots of earthquakes beforehand!

      I don’t think I’ve seen those specifically, but there are a good number of similar deposits around North Beach.

Some parts of the Salish Sea area are rising by nearly a centimeter per year even 15,000 years later!
