Salt is a raw resource in Ark Scorched Earth and is relatively easy to find in quantity. While the obvious sources are the large off-white formations commonly found out in the desert, there are other much easier places to find Salt.
The most obvious place is the large Salt Deposits that are found mostly in the outer desert. But that is not the only good place you can find Salt. There are bones all over in most areas and many of these can be harvested for Salt. So far I've found that you need a Pick for this with a Metal Pick being the best.
