Salt Lake in New Mexico is an example of what is know as a Maar. A
Maar is a lake formed by some sort of volcanic activity. This lake
is a flat saline/salt lake that formed across the crater of an inactive
volcano. It is about 6,500 feet across and 400 feet deep.
Great Salt Lake is the saltiest body of water that is inside a land
mass in the Western Hemisphere. Rivers like the Bear, Weber,
and Jordon all flow into the Great Salt Lake, but there is no way
for the water from these rivers to flow out of the Salt Lake. Water
collects until it overflows its banks. You can see the whitish areas
that have flooded in the past.
