Trees in the desert

Many many years ago as the settlers were moving west on the old Butterfield Trail (over there about 4 miles) some of the settlers took up homesteads in what we know as the desert. Not having any shade for their afternoon "siesta", they planted trees, spruced up their yards with bermuda grass and cute little flower gardens. Or, as another story goes, the deserts used to be forests till the loggers cut every thing to the ground leaving only a few trees for shade for the loggers "siesta" time. Yes, there are trees in the desert.
