In 1883, 42 men labored all summer trying to bore a tunnel through the Mogollon Rim. They didn't succeed.

Here's a view looking down the trail from the trail head. It is one half mile down to the bottom and another quarter mile up a steep cliff to the cave.

Only a few feet more to the cave entrance: There is an old stone dwelling at the cave entrance.

Here is a shot of a window in the stone dwelling.

The cave entrance is just to the left behind the trees.

I'm now entering the cave after checking for bear and mountain lion prints in the soft sand. I did not see any prints but I still went in barrel first. My hiking companions bailed out on me after the first 200 yards so I was alone.

Here's a view looking deep into the cave.

I'm now approaching the end of the cave.

Here I am looking back towards the opening from about 20 feet.

Here's a view looking out the window from inside the stone dwelling.

Here's a shot of the stone dwelling's door. The cave entrance is just to the left.

Across the road (General Crook's Trail) from Colonel Devin's Trailhead is a small log cabin.
