1960 version of USGS Thatcher AZ Topo Map. One area of interest: N 32.88943 W 109.91175 The apparently historic Bear Flat Canal vanished with few traces some time after this 1960  USGS Safford Basin topo map. This seemed hugely oversized and may have been some sort of real estate scam. The underlying artesian source was unlikely to have  been prehistorically ignored. Find some field notes here. One dirt road access is N 32.75700 W 109.71779. Click to expand the image.
