Question:

Please describe to me how a 'rain shadow' works in mountainous regions. A great example of a rain shadow is in Washington State, where you have the wet Cascade range to the West, followed by a much drier climate to the East.

Calvin P.
Answer:

A rain shadow occurs in mountainous regions and pertains to the amount of rain certain regions receive over others. Typically, the side of the range that receives weather first (West in most U.S. mountain ranges) is much wetter than the Eastern side. The leeward side (downwind) is drier because the preceding mountains have already forced precipitation out of the clouds.

Question:

Ancient Lake Bonneville, which occupied modern day Salt Lake City and the surrounding valleys, suddenly burst its dam and rapidly drained to the north. This occurred during the recession of an ice age. Can you think of why this lake might have burst, and what the outcome might have been?

Calvin P.
Answer:

Ancient Lake Bonneville was created due to a damming of the lake by glaciers. As the Ice Age receeded, so did the glaciers. Eventually, the glaciers damming the lake broke, which created an intense flood unlike any we have seen in modern ages. This torrent of water created new rivers and waterways that we enjoy today, such as the Snake River and the Columbia River.

Question:

John Wesley Powell, who was an American Soldier, geologist, and explorer, is credited with discovering what natural landmark and current National Park? What did Powell do to discover this landscape?

Calvin P.
Answer:

John Wesley Powell is known for many things, the most important being the first descent of the Grand Canyon. Powell, who was a soldier before gaining an interest in exploration, was the first man to conduct an expedition down the Green River, which eventually led into the Grand Canyon. Powell was responsible for mapping this extensive desert corridor and was the first person to successfully negotiate the rapids of the Grand Canyon.
