Forming the land of Globeville's close by neighbors.

       Globeville itself isn't a very interesting zone when it comes to plates and volcanos, but not too far way we can see evidence of action.

To the northwest of Globeville, a short ten hour drive according to google maps, is the Yellowstone national Park. Click on THIS LINK to see an outline of the sunk in ground caused by an ancient super volcano. When it erupted hundreds of thousands of years ago the ground underneath was weakened by lava chambers and molten rock. The top of the volcano collapsed on itself creating a gigantic Caldera, a dip in the ground sometimes confused for a crater. Craters are cause by the explosion of a volcano, not collapse. In the Caldera there are basalt rhyolite deposits at the surface. We call these deposits Plutons. Exposed by erosion, we can now see these former chambers of molten rock. One might also find a Rhyolite dome in the Yellowstone Caldera where viscous magma is again building up inside.

      To the direct west of Globeville are the Rocky Mountains. Near them are some beautiful normal faults. We can see triangular facets where the earth "snapped" and rose up creating fault scarps.
