There are some rock pictographs east of Sparks off i80 towards Mustang Ranch. I forget exactly where though. They are near the Truckee River. There is an excellent pictograph site off US 50 about 15mi east of Fallon. This area is rich in Paranormal Activity. There are caves there, where they found Ice Age Indian remains. See the photo below, of an actual Spirit that I unknowninglly photographed on site.
If you drive to Auston NV, and drive another 30mi east on US 50, there is the Hickson Petroglyphs, near Hickson pass. This is another Paranormal Area. Painted Cave, Just 20mi south of the pass, on BLM dirt roads, is a Paranormally Charged area. There is a primitive campground there. There are portals to other dimensions there, that causes spacial disorientation. This is a very weird area. The cave has many Indian signs in it painted on the walls.
Pyramid Lake, also has petroglyph sites along the western shores. I done lightning photography there. See my photo below.
Lake Tahoe has few petroglyphs on the rocks near that tunnel east of Stateline. Christmas Valley has good hiking along the rim trial that boarders the eastern side ridges. I found excellent arrowheads there. There are Mountain Lion and Bear there.
Consult local Nevada Road Maps. Carson Valley also has Indian Rock art. You are in an rich paranormal active area. PM me for more links and information on the area.
Red Spirit at the Fallon Petorglyph site off US 50. I did not know I caught it on film, until I had the film developed.
