Possibly contributing to the rapid uplift is the tectonic extension in Nevada and a response to flow in the mantle. Seismologists indicate the mountain range may have risen when a fragment of lower plate peeled off the bottom of the lithosphere allowing the "speedy" uplift, like a ship that has lost its keel. In comparison, other ranges, such as the Alps or Andes, are being formed in an entirely different process caused by contraction as two plates collide.


The rise by itself is not as interesting as the possible cause. Probably nothing for urgent concern but then, being unique, who really knows.

Please give more data in the initial post. How much of a rise? How rapidly? Things like that would help clarify what the thread concerns. Thanks.

The first sentence in the linked article says:


1 to 2 millimeters per year. That’s roughly a half-inch every 10 years.


That's pretty fast.

Thanks (I know the page is linked but it's good to get the data into the first few posts so people know what they're dealing with). Now the question is if that rise is fast, or around normal for the specific mountain range. I've only seen them when I've been to Vegas, and am surprised how high they are considering how long the snowcover stays on some of the peaks.

I am not really sure if that includes the three sisters volcanoes but the rise in the surrounding country there is
a matter for concern....if there is lava building up underneath them....
