- Examine the above image (Figure 14.23) from Rainbow Basin, near Barstow, California. Notice the rocks are bent and tilted into a syncline (fold). Using the Geologic Principles, relative dating terminology, and your observations of the rock layers, discuss when the folding event likely happened.
2. The image above (Figure 14.24) is from a section of the Grand Canyon. Place the following geologic events in correct order, from oldest to youngest. Support your answers using the Geologic Principles.
- Muav Limestone
- Sedimentary rocks of the Grand Canyon Supergroup
- Tilting event
- Unconformity Z
- Unconformity X
- Tapeats Sandstone
- Sedimentary rocks of the Supai Group
- Bright Angel Shale
