Just the usual 900 year old volcano with adjacent lava field.
.. followed by a meteorite crater. Along with the meteorite that created it.
Petrified forest. Cute, but I prefer living trees.
Canyon de Chelly. Ancient Native American ruins. Recognized this place from westerns.
Monument Valley. Monumental awesomeness.
Camped in Navajo National Monument. Great campground, spectacular sunset. Slept next to some other ancient Native American Ruins.
