Pat Lewis announced that Viva La Lune will be held this Friday after the meeting. Keith Allred Astrophoto SIG will be held the first Sunday in September at 2 p.m. Contact Keith for more information. Ancient Petroglyphs John Rudolph of the Battle Point Astronomical Observatory on Bainbridge Island, talked about petroglyphs, which may be records of astronomical observations by American Indians John has explored sites in the western United States that contained petroglyphs of what may have been records of astronomical observations conducted by Native Americans hundreds or even thousands of years ago. The first site John discussed was Willow Creek near Susanville California. The second was on Bainbridge Island.
Willow Creek is above the Great Basin Area.
There is an escarpment of basalt 200 feet above the stream bed where two chambers exist. On the northern end, a little crack forms a cave. Back 27 feet into the cave exists a petroglyph 18 inches across. It consists of a serpentine line with a circle with a dot in the middle. This could be the sun or moon.
