Question

1. Using the Ennis Gulch Quadrangle, which kind of mass wasting most likely left the deposit seen southwest of Ennis Gulch, a type of flow or a type of slide?

2. What evidence shown on the map supports your answer?

3. Using the 5,000’ contour as the top of the deposit, how thick is the deposit at the end (the "toe") of the deposit?

4. Although the deposit is somewhat irregular, assume that it is square or rectangular in shape.

Estimate the length of the two sides from the toe of the deposit to the point that it is in contact with the mountain front. Make sure you review the instructions for obtaining these measurements.

Finally, calculate the surface area (in square feet) of the deposit using standard area calculations.

5. Assuming that your answer to the previous question above represents the uniform thickness of the deposit (a simplistic assumption), calculate the total volume of the deposit using standard volume calculations.

Explanation / Answer

1)It is a type of of a slide mass wasting.

2)As, the path taken by the rock stara is downward as shown in the map so it is a slide. Here, portions of the mountain slope fail and slide down in defined units.

3)diagram is not clear for answering this answer like this 14ft  for 6800 contour

4)400 * 400 = 1600ft2

5)Surface area should be multiplied with thickness. That is, 1600 * diagram is not clear for answering this answer like this (Surface That is, 1600 * 14 = 22400ft3)
