I found the area below the pronounced cottonwood stands to be the most consistent source of the spring itself. Given the existence of what I have now verified as the town of Tombstone's old well maintained (there is obvious new bolting hardware visible) aqueduct piping system (see photos) from the Huachuca Mountains that dominates the audible water sources cascading location - this seems the best location to pinpoint the springs origin or there-abouts. Though the cottonwood stand above would document that the likely possibility of seasonal seeps and such exist in the vicinity. Perennial Murray Springs arises in the gorge running from below the Clovis Site / Murray Springs entrance to the San Pedro RNCA accessed from N. Moson Road just over a mile north of AZ Hwy. 90 east of Sierra Vista.
