60 Hikes Within 60 Miles: Albuquerque (2nd edition)
54. Oh My God
60updates bonus hike:
From the OMG gate, take the fence road east about 2 miles to a drainage.
Follow it downstream about a quarter-mile. Fort Red Dog is a distinct
reddish-orange formation on the rim. You'll know it when you see it.

There's a cave (tunnel, actually) in an alcove about 200 yards SW of Red Dog.
You might need these coordinates to find it:

N35° 11' 34"
W107° 03' 16"
