Just outside of Jemez Springs, New Mexico, we turned off (over?) Highway 4 onto Forest Road 485. The road snakes through the Rio Guadalupe Box Canyon in the Santa Fe National Forest and near the unincorporated town of Cañones (or Gilman) and eventually turns into Forest Road 376. On this road are a series of tunnels known as the Gilman Tunnels. The tunnels were blasted out of the rock by the Santa Fe Northwestern Railway (SFNW) to create a pass used to haul lumber from the Jemez Mountains. The railway opened in 1924 but never recovered financially from the Wall Street Crash of 1929, and ceased operations in May 1941 following flood damage from the Rio Guadalupe. Several movies have been shot in the area including The Lone Ranger (2013) and 3:10 to Yuma (2007).
