17 April 2002, Canyon de Chelly National Monument, Navajo Nation: We are living on the Rez now, subject to local laws and customs. Alcohol forbidden by federal law, no photography of local people, homes, land or their animals without permission. No hiking without a native guide. Canyon de Chelly figures prominently in recent Navajo history, but these ruins all predate the current Navajo owners. This is the 700 year old Puebloan village called Mummy Cave Ruin, viewed from about 1000' above.
