Traverse of the Sierra Nevada de Santa Marta; Pico Simmons. Tom Simpson and I entered the range from above Ciénaga Magdalena (San Pedro de la Sierra), went into the paramo by Cuchilla Cimarona, and continued along the western spine of the Viscungue valley and up this valley to the base of Pico Simmons, which we climbed. The two of us kept on around the “Horqueta” by a southern route, down past Noboba (lake), down the Donachui and on over to Atanquez. This I believe is the first complete traverse of the Sierra. We were there from December 29 to January 12, 1976.
