Welcome to my Atlatl Rock web site!
When travelling through the southern part of the US, we visited the Valley of Fire State Park, NV
first time on September 12, 2008.
Beeing interested in historic places, we followed the signs to the Atlatl Rock engravings (Petroglyphs)
not knowing what to expect. We took some pictures of the rock art and enjoyed the beautiful park.
Back home in Germany, when I started to screen the 4000+ pictures I had taken during the 4 week long trip, I
stumbled upon the pictures taken at the site and realized, that the shadow of the rocks just passed through
the concentric circles and the cross of the rock engravings. Beeing an professional astronomer and beeing
interested in the history of astronomy I had seen similar alignments in books, but never had I expected to see
such an alignment myself.
Immediately I realized that this was probably set up to mark the autumnal equinox. We were there
on September 12, i.e. 10 days before equinox 2008 at about 11 am local time, almost the right time so see the
shadow connect the circles and cross if their purpose is to mark the equinox.!
September 12, 2008 11:32 PDT;
10 days before autumnal equinox
If you hapen to have photographs of the Atlatl Rock Petroglyphs with the shadow visible,
please send me the picture with time and date of the exposure. If you agree it can be to be included here!
I checked books on ancient astronomy (archaeoastronomy) to find out if Atlatl Rock was listed there, but so
far without success.

- North Shore Inn at Lake Mead Overton, NV
This nice hotel is located about 29 km (18 miles; 30 minutes) from Atlatl Rock and is our favorite accommodation
In June 2011, when temperatures reached almost 50°C (120°F), the pool was a great relief.
- In my opinion
the most beautiful photographs from the whole Valley of Fire State Park
