Location	Activity Description	Google Earth Content
1. The Grand Canyon, AZ	Using the ruler in the tools, measure the width of the Colorado River and, the vertical drop from "Dawn Light" Toroweep to the Colorado river.	I will put a placemark with information about the erosion that has taken place and is still happening, shaping the grand canyon. Instruction given to complete the activity.
2. Devil's Tower, WY	Using the ruler in the tools, measure the length in feet from the top of the tower to its base. Also, measure the width and lenghth of the top of the tower.	I will put a placemark on the top of Devil's tower and will format it with information from Wikipedia and some images of the surrounding area to show how erosion can change the landscape. Instruction given to complete the activity.
3. Arches National Park, UT	Using the ruler, measure in feet the highest point of the arch straight down to the ground. Also, measure in feet the length of the base of the arch from the outside of one side to outside of the other side.	I have put a placemark on the Landscape arch and will format it to show different pictures of the arch and make a path to other arches close by. Instruction will be given to complete the activity.
4. Perito Moreno Glacier, Argentina	Use the ruler to determine how long, in feet, the glacier is from the back to the front and then from side to side.	I have put a placemark on the Perito Moreno Glacier and will format it with pictures. I will add a path to show the U-shape of the mountains -- a characteristic of what glaciers do to the landscape. Instruction given to complete the activity.
