Dave and I recently hiked forty-plus miles along the Salkantay trek to Machu Picchu in Peru. In fog, rain and snow, we trekked to the 15,213-foot Salkantay Pass before descending into a river valley. Days later, we crested another pass and caught our first glimpse of Machu Picchu on an opposite mountainside. Our trek gave us an understanding of why the Spaniards centuries ago never discovered Machu Picchu.
