This morning we headed out to the airport to get a helicopter flight over the canyon. It was fantastic. The canyon is huge, it is 277miles long and averages 16 miles across. We got to see the Colorado river when it is green and the little river was aqua. This is due to the chemicals in the rocks and these colors only show about 3 times a year. We were lucky to see this. Afterwards we went to a Navajo Indian show and market then back on the shuttle to the canyon where we could walk along the rim and view the canyon at different spots. Saw some more squirrels and deer.
