Monday, 13 April 2015 - Took a helicopter to the Havasupai village of Supai, hiked two miles to Havasu Falls stopping at Navajo Falls for lunch, marveled at the striking blue water surrounded by red rock and green trees, observed the travertine formations built up over time from calcium carbonate in the spring-fed river, and spent hours photographing the falls as the sun set and shadows changed the light.
