Badwater is south of Furnace Creek (maybe 20 miles) in Death Valley.
Pyramid Lake, north of Reno is interesting. I found the shoe tree east of Carson interesting, but I don't know that it is photographically interesting or not. Lake Tahoe can be good, if not a zoo. Virginia City is good, as is the mine south of town, but some say the bldgs are dangerous (not because of the bldgs, but the local ne'er do wells). That was years ago.
I have found Nevada's wide open spaces beautiful and when I just stop beside the road and poke around I find all kinds of interesting and sometimes photogenic opportunities.
