In the coolness of late afternoon at 7,700 feet in the Buffalo Creek Recreation Area, a golden light filtered through tall pines, accentuating the intricate shadows of rock outcroppings looming over the Colorado Trail.

Five men in their 60s were gathered on the trail, reliving an adventure they had as high school students from Pennsylvania when they spent a month working to help build this section of the trail.
