We left Texas and continued west through New Mexico until we came to Petrified Forest National Park. We drove south through the park to the Rainbow Museum, then turned west again.
Thursday night we stayed in Flagstaff, then visited Walnut Canyon National Monument Friday morning.
We drove north to Las Vegas, stopping at the visitor center for the Lake Mead National Recreation Area on our way.
We also stopped at the Tule Springs Fossil Beds National Monument north of Vegas, but currently there isn't much there. We continued north towards Reno, and stopped in Tonopah. We arrived back in Bend Saturday evening.
