Chuck and Andy try to figure out "just how deep you can go" when they head out on an adventure to the Grand Canyon. Bighorn sheep are known as the guardians of the canyon by the Hualapai Nation of Arizona, who have lived here for many hundreds of years.  They own part of the Grand Canyon and its golden eagles are sacred to them.  They have a special message for Chuck and Andy: We are all keepers of the canyon. We all share the responsibility of taking care of Mother Earth.
