Beautiful photographs @bigtom13! I love seeing new pictures of old
places I've not seen before. For many years I've read and looked at
lots of sites and petroglyphs, most are telling us about the sun and
moon, time and navigation, hunting and life. The seasons from
solstices to equinoxes. The ancient watchers kept good records! :-)

Sometimes turning the photo into a negative helps to see the patterns
better and when at a site putting some water on the rock helps reveal
even more.
