i think the earth went through a dramatic change 12,000 years ago. a great geologic upheaval that changed landscapes. and i thought about salt lake city and the ancient Anasazi indians.Why is water in salt lake in utah salty instead of freshwater? does it used to connect to the ocean?
Reason for being so salty:
The Great Salt Lake in Utah is salty because it does not have an outlet. Tributary rivers are constantly bringing in small amounts of salt dissolved in their fresh water flow. Once in the Great Salt Lake much of the water evaporates leaving the salt behind.
You can see the terraces, in the surrounding landscape, that were eroded 30 000 years ago when the lake (Lake Bonneville) was much larger. The terraces follow Lake Bonneville's shoreline and at some spots are over a thousand feet hight than Salt Lake. At the end of the ice age, the climate became drier and Lake Bonneville began to evaporate. What was left is now the Great Salt Lake.
The Anasazi (ancient) Indians were ancestors of the Pueblo Indians living in scattered villages in Colorado and southern Utah. Around 1300 AD, the Anasazi disappeared.

Well, all water is slightly salty. A salt lake is created when a large body of water gradually evaporates and creates a smaller body with the same mineral content as the big one had.
Great salt lake specifically is the remnant of a prehistoric body of water known as lake Bonneville, about the size of Utah, That existed 32 to14 thousand years ago.Why is water in salt lake in utah salty instead of freshwater? does it used to connect to the ocean?
Salt is a commonly found mineral combination. Utah is one of the most mineral rich places on earth. I understand that you can also find a lot of salt in Detroit. I seriously doubt the reason for the existence of the similarity is the same at both locations.
