Gold River Canyon“s Dead [EPUB ebook] 

An adventure beyond belief into the Flat Tops Wilderness of the Western Colorado Rockies. Emily, Warren, and Joe, three ordinary people break from the drudgery of everyday life to go on a search into an unexplored region of a high mountain area led only by a rough, hand-drawn map and the depiction of a box canyon guarded by the “Place of the Skull.” If you survive, you“ll be glad you went to Gold River Canyon.
