27 Mar 13 As a big fan of writing about the early Americans, meaning the peoples of maybe 10,000 years ago who populated the two continents, it is always fun to come across items that are believed to have been left by their cultures. I have only seen such in a couple of locations, the majority of which were located on the confines of the Naval Weapons Station in China Lake, CA, with the remaining sightings in WA State along the Columbia River on Highway 90. The art work is quite interesting to see, and even more fun to try and photograph such that one can realistically capture its simple beauty. Even more fun is to try and identify what, exactly, the artists were trying to convey. I'm sure there are some who think they know but I would wager such is not very likely as we have nothing that captured the actual items and/or events being portrayed. If you've not visited anywhere where there are petroglyphs to view, I would encourage to try and take in such a location next time the opportunity presents itself. This is one of many shots taken back on the '09 trip to Montana. D300; 18 - 200; Aperture Priority; ISO 200; 1/250 sec @ f / 8.
