Monroe peak is the remains of a large stratovolcano from years past.
Approximatly 23 million years ago this was a lar
Looking about you tell me:
- The stones that are about you, do they appear to be volcanic or not? If so are there the volcanic gas bubbles in the stone? Describe the stone.
- Is there any apparent evidence of the Monroe volcano or the resurgent dome that you can see? Describe your opinions.
- Looking to the SW you can see another large stratovolcano the tall peaks miles away. - The Mount Belnap caldera/stratovolcano. After all these years can you tell if there was a volcano or resurgent dome there? Describe why or why not?
- Photos welcome.
- Add a photo of you from the location or of an identifiable item (paper with trackable name). Posting a photo pulled from the internet, or photoshopped will result in instant deletion.
ge active volcano that covered an area twelve by nine miles. It was a massive volcano that was extremly violent. Explosive pyroclastic flows and many lava flows build this volcano up. The pressure from the vast magma dome under the ground feeding the volcano complex nd its many outlets. (see upper figure) In fact over 43 square miles of ash and pyroclastic material was ejected into the area.
You can picture it like a sprinkler system. When the pressure is on they pop out of the ground(see the top of the three graphics)
Eventually the pressure dropped. The pressure pushing the magma out of the ground began to subside. The weight of the ash, lava and other material above the giant magma dome begins to push down. Eventually this giant dome collapses in on itself. Creating a pile of jumbled stone and faults scattered around the area.
Now think back at the sprinkler example. When the water pressure drops they sink back into the ground. This creates a jumble of material (see the middle of the graphics)
Finally in the case of the Monroe caldera the pressure began to build again. It began to push some of the broken material back up. Forming a resurgent dome. In this case we were most likely looking at 10-20 feet of rise per year for many years. Causing the formation of the mountains that you see now. (see the bottom picture) 
Look about for a benchmark for 11,232 feet
