Homeward-bound, Day 1
Struck north again on faithful Interstate I7 to Flagstaff, where we took the I40 eastbound to the Painted Desert. A colourful area created by the erosion of Chinle rock deposited 200 million years ago as silt, the layers of rock exposed are different colours. Photos don't really do justice. The road through the park includes the Petrified Forest area, where trees that fell into the silt/volcanic-ash mix had their fibres replaced by minerals. They lay buried in the Chinle rock until erosion exposed them, in some cases making them look as though they had just fallen.
To Holbrooke for the night. New Mexico tomorrow.
