This is New Mexico arch number 354, aka NM-354 or Arrowhead Arch. This arch is in the Toltec Gorge at one of the best places to overlook the entire canyon. It is in a dangerous spot on the rock face that goes over the top of the tunnel on the Cumbres and Toltec RR, so exercise caution and do not go there without ropes and safety gear. I do not think the chest is at this arch, too dangerous a spot, but rather line of sight will let you know when you have ‘found the Blaze”. The GPS coordinates for this location are on the website with the photo. Do a Bing or Google search for NM-354 arch.
