Community Property in California. California is a community property state whereby it is presumed that each spouse has an undivided one-half interest in any property acquired during the marriage while domiciled in California (California Family Code Â§ 760).
The Great Salt Lake is salty because it is endorheic...that is, it has no outlet to release water except for evaporation. As a result, mineral salts accumulate over time, resulting in either a very salty body of water (the Aral and Dead Seas and the Great Salt Lake) or extensive salt flats (Such as Bonneville in Utah).
In this way, over hundreds of millions of years the ocean has been gradually becoming more salty. Now, the second part of the answer has to do with how salt gets into the rivers. It comes from disintegrating rock, like the granite that makes up the Sierra Nevada, and from volcanic eruptions.
