It had an article about petroglyphs in Nevada, highlighting Grimes Point Archaeological Area (a National Recreation Trail [whatever that really means]).
So Saturday morning as we were trying to decide what to do, we decided to check the site out.
Our hour long drive brought us to the deserted site, just 100 yards off of Highway US50. It was really well designed, with a gazebo providing much needed shade, petroglyph themed seating, picnic benches, and restrooms.
Just in the short time that we were there, half-a-dozen cars from various western states stopped for the bathroom. Some people even took the short natural trail to the petroglyphs. If it weren't for that bathroom, the place would be largely unappreciated.
The trail is in excellent condition -- Tucker's stroller did just fine. While the trail would only take 10 minutes to walk (with kids), the self-guided tour signs give you the opportunity to stop and admire the history of the area. The entire area had been hundreds of feet underwater at one point, which explains the weird (and fairly ugly) terrain of the valley. The petroglyphs are believed to be thousands of years old, which leaves their purposes and inteprations largely a mistery.
