Petroglyphs.

Finally a picture of the petroglyphs on A-mountain. They were engraved by members of the Hohokam culture.

And I also made some test-shots with my tele-converter, a Vivitar 2X7P, for a Tamron AF 70-300mm f/4.0-5.6. It worked fairly well, but since it was a hot day there was quite some heat haze.
