1. GEOLOGY FIELD ASSIGNMENT by Cydnee Sciacqua

2. Rock Types – Igneous, Metamorphic, and Sedimentary

14. Mission view from other side of wall In the bottom two photos you can see the scarp that was created from the fault line.

17. Yosemite National Park Erosional forces acting upon different types of uplift-created joint and fracture systems are responsible for creating the valleys, canyons, domes, and other features we see today. Half Dome (center of picture) was created by such erosional forces and is an example of an exfoliation dome.

18. Mass Wasting Talus form at the base of a mountain. Gravity caused rock to break free leaving the uneven face on this formation. The face of El Capitan, a prominent granite cliff that overlooks the Yosemite Valley, was created by mass wasting.

19. Erosional Forces A tributary glacier created the u-shape of the Yosemite Valley. Bridal Veil Fall patiently works on eroding the side of the mountain and the rocks below.

22. Continental (continued)
