|
|
Bryce Canyon National Park
|
-Not really a canyon!! miss-named, it is actually a giant amphitheater
created by erosion -Tertiary -Southwestern Utah -Lake and delta deposits -Hoodoo’s! …A pillar of rock, usually of fantastic shape… left by erosion |
|
|
Arches National Park
|
-Utah
-Thousands of natural stone arches throughout the park -Greatest density of natural arches in the world -Millions of years of deposition, erosion… lalala -Entrada sandstone → Jurassic} Makes up the arches Joints -Natural fractures in rock structure Joint Sets -Joints that form in sets of vertical fractures & equally spaced/parallel |
|
|
Canyon Lands National Park
|
-Colorado and Green rivers meet
“Island in the Sky Mesa” -High standing area between the two rivers Upheaval Dome: rocks have been uplifted in circular pattern, island in the sky messa (park on the canyon lands) plug of slat rising up below rocks, or a meteor The Needles -Prominent fins with spiky tops made from erosion The Maze -No roads, solo wilderness… thousands of winding, un marked canyons Cataract Canyon -14 miles of big white water Angel Arch |
|
|
Capitol Reef National Park

Rocky Mountain/Glacier National Park
|
-Mountains produced by thrust/reverse fault
-subduction zone under the n. American plate shallows out→ 2 plates converging, areas above the plates become weak and break= rocky mountains -Precambrian age -Southern -Reverse rocks are very steeply inclined -Precambrian metamorphic rocks -Northern -Faults are very shallow -Precambrian sedimentary rocks |
|
|
Voyageurs National Park
|
metamorphic rocks - older than 2.5 by
has been covered by glaciers |
|
|
Isle Royale National Park

elongated surrounding islands -> due to the direction the glacier went
pre-cambrian volcanic rocks with conglomerates (basalt) 1.5 by Lake Superior, ship wrecks |
|
|

in the rocky mountain region geographically, but not apart geologically
Were not formed by Laramide Orogeny. They are much younger and are an example of a fault like mountain produced by the stretching of the crust.
