Salt Flats

Salt flats are usually flat, as their name implies. One salt flat that doesn’t adhere to this description is “The Devil’s Golf Course” in Death Valley National Park. 

This salt flat  was once a lake. As the water evaporated, the minerals that were dissolved in the lake water were left behind. Since the surface remains dry, the salty  surface has weathered over time creating sharp sculptured salt formation.

weathering: The breaking down of solid surfaces by factors including wind and water.

Before this salt Classification flat became a national monument in 1934, exploratory holes were drilled. It was discovered that the salt and gravel beds extended to a depth of more than 1,000 feet (300 m). Later studies increased this to depths ranging up to 9,000 feet (2,700 m).

Math Challenge

Using dimensional analysis, determine the depth of the 9,000 ft. salt flat in miles.
The conversion factor between miles and feet is:

1 mile = 5,280 feet
