SLC is in a valley with a briny ancient lake to its northern/northwestern side. This briny ancient lake didn't used to be so salty (or small)- it used to be much larger, covering thousands of square miles of the Great Basin in the Western US. It was over 320 miles long, over 100 miles wide, and over 1000 feet deep at its peak: which made it larger and deeper than lake Michigan is today. SLC is located on the bottom of the prehistoric lake Bonneville.
SLC is heavily populated by followers of the LDS religioun, and it does contain some remnants of polygamy (even though the LDS church does not condone polygamy any longer). Some holdouts, also known as "heathens" or "gentiles" brew and make SLC a better place.
Just kidding, it's Salt Lake City- in case you didn't get it already But all that I said is actually true, however.
