Nevada Treasure Hunters - Ghost Town Guide, from Nevada Publications, po box 15444 LV NV 89114. (I bought it many years ago) It includes a list of books on Ghost Towns of the Southwest, and maps.

Did you try local libraries? Free!

Map stores in the Las Vegas area had maps and guides, in the past. I'm not a trash hunter, just photographer, but the Treasure Hunting guides have Ghost Towns included.

Have fun, and don't forget to take along extra water.
