1a. What types of mass wasting plague the state of California? Describe the various reasons why mass wasting commonly occurs there. What advice might be given to land developers in California to reduce the risks of mass wasting?1b. While hiking up a mountain valley, you come upon a lake, dammed by wall of unconsolidated sediments. You suspect that those sediments may have been deposited across the valley by a glacier that has since melted away. Describe thoroughly what those sediments would look like and why they could not be from a stream. Viewing up the valley, what other clue would support it being a glaciated valley rather than a stream valley? Large boulders are strewn haphazardly throughout the valley as well? Does that evidence support a glacier depositing the boulders or a stream depositing the boulders? Defend your reasoning.
