When it rains, it pours

Something that really amazes me is what I've learned from bringing this up. Ever since moving to the west side of the valley, I noticed black tank cars coming in and out of the area and sometimes sitting on a siding that runs along Grand Ave. (US60). There's a spur that heads west a few miles south of us that cuts across Grand Ave. I frequently see these cars lined up along this spur as well, and I never knew why until now. Apparently, these cars contain LPG which is stored in the space left open in that Morton's salt mine that I was talking about. It kind of makes sense, but I never put the two together. I also found where there are other active salt mines in Arizona. A large one up around Holbrook and another outside of Kingman. A geology site says that there are more that have not been tapped.

It could be, like the Great Salt Lake, these deposits were a result of Arizona being underwater a very long time ago. According to that site, that was some 245 million years ago. It just occurred to me, but the valley where Phoenix and surrounding towns are located is called the Salt River Valley, and the Salt River runs right down through the center of town. Gee, what a coincidence, I always wondered why they called it that since the river isn't salty when it runs, which is only occasionally when the open the gates at Roosevelt Dam upstream.

Enough geography for one day, I was never good at that anyway.
