Even at a 10,221-foot elevation, small trees are taking foot on the rusty main line and siding at the summit of the former Rio Grande main line over Tennessee Pass. Still “railbanked” by Union Pacific more than twenty years since the last passage of a train, the future of the route still hangs in a precarious balance. This view looks south/southwest toward the second-highest mountain in Colorado, the 14,421-foot Mount Massive.
