Thanks. The petroglyphs are on Stansbury island. About an hour west of salt lake city. The 2nd largest island on the lake. There is a dirt road leading to the island now with evaporation salt flats on the sides, but in 1869 it was surrounded by water with just a peninsula connecting the island to the south. The east side of the island is private property but loose. I found two hillsides completely covered with petroglyphs about 2 miles apart. One of the sites has a few panels of Dinwoody forms. Identical to ones in the Wind River range in Wyoming. These Dinwoody monsters are tied to the Shaman religion of the Shoshone. There are 4 petroglyphs with the bow and arrow. This one below my bow is the only one with very bendy tips. I would like to think this is a sheep horn bow deception. Looks like a moose petroglyph right in front of the archer and a couple unmistakable bighorns in front. I noticed both the petroglyph sites are located next to rock outcropings forming high walled game drives.
