The Grand Canyon is not on the way to the Route 66 but we are so close to it that we decieded to go there. We find the Grand Canyon with clouds and rain what the nature needed it, there is a long terme of dryness and it is still warm and gets hot up here on 2200 meter over the sea level.
If the sun comes through the temperature rise up to 25° degree.
It is a giant Canyon over 16 km wide and 1.6 km deep. The Colorado River has formed it over 4 Mio years and still forms it. But it goes slow and takes its time in about 1000 years the Canyon will be only 1 foot deeper than now.
