About an hour northeast of Las Vegas, not too far off Interstate 15, is Valley of Fire State Park. We just had time to break up a drive with a couple short hikes. The park has many petroglyphs. A very easy climb up some stairs on Atlatl Rock is this collection that is an estimated 4,000 years old. The fellow with a spear is called an atlatl. The picture after that is the view from the glyphs with the rocks aglow showing how the park got its name.
We didn’t find the petroglyphs that are in a box canyon on Mouse’s Tank trail, but it did provide great scenery.
The hike does show the tank and provides nice viewpoints.
