Testing your Johnson
by Randal_Schulhauser

Some History: In 1882 the Atlantic and Pacific Railway began constructing the final sections of a northern route through Arizona connecting Kingman, Flagstaff and Winslow. The grade up the plateau between Ash Fork and Williams proved to be one of the more challenging sections. Engineers finally selected a route through Johnson Canyon requiring some bridging and the only tunnel to be constructed along this northern route.


In 1897, the Atchison, Topeka and Santa Fe RR acquired the Atlantic and Pacific RR assets and operated the route under the ATSF subsidiary Santa Fe Pacific RR. A year later, tragedy struck the route when wooden timbers supporting the Johnson Canyon Railway Tunnel caught fire. At least two men perished fighting the blaze. This prompted a reconstruction of the tunnel incorporating steel boilerplate to replace any of the wooden shoring.

As the rolling stock began to carry weight beyond the capability of the original bridges, a combination of retaining walls with fill replaced many of the original structures. The exact date of this construction is unknown, but photos thought to be taken in the late 1930's showing the tunnel's western entrance, no longer have a trestle. A Santa Fe RR postcard from 1937 shows the tunnel and trestle in place. We can report with a high degree of confidence that many of the concrete retaining walls are dated "1921".

During WWII, this rail route was considered of such strategic military importance that guards were placed by the tunnel to prevent sabotage. Wooden remains of the guardhouse can be found today above the tunnel entrance near a foot path. In 1943, the Office of War Information hired a photographer named Jack Delano to record rail activity along the Santa Fe route. I found two photos of Johnson Canyon by Jack Delano in the War Information archive. It's always interesting to compare some of these older shots to today.

It appears that the Santa Fe RR used the steeper Johnson Canyon route for east-west rail travel and the gentler "Coconino Cut" route to the north for west-east rail travel through to the early 1960's. The line was finally abandoned in 1962 and the rails removed when the "Coconino Cut" route was double-tracked.

The Hike: Start your hike from the trailhead near the abandoned settlement of Welch Station located near the intersection of FR6 and the abandoned Santa Fe railway right-of-way. If you walk over to the northwest corner of this intersection, you will find a large concrete slab. This is all that remains of the old Welch Station. If you explore the immediate vicinity you can find remains of some smaller concrete pads, presumably from other support buildings.

The hike east along the abandoned roadbed begins on small flat plain with little grade that soon becomes surrounded by gentle rolling hills. We discovered squash and small gourds growing along the embankments (some of which made their way back home to supplement a Halloween fall season display). There is an intact bridge crossing a small wash that had a particularly high concentration of these yellow and green gourds.

Immediately past this bridge is the first noticeable rock cut. As you walk through the cut you will pass under some high voltage transmission lines and will soon be rewarded with your first sweeping views of Johnson Canyon.

Continue hiking along the curved railroad grade. Your eyes may be drawn towards the canyon by some of the fall colours. In the distance your path is made obvious by the steel reinforcement walls used to prevent erosion of the railroad grade. You begin to find railroading artifacts along the trail... a large rivet here and there, an iron rail, footings to hold a signal light, or even a rail spike.

We begin to close the distance between us and the steel reinforcement walls without being able to spot the tunnel. Johnson Canyon seems to be at the height of its fall colours dressed in spectacular yellow or green foliage. Some tall Ponderosa Pines are evident in the canyon. As we make our way around a bend I can spot some masonry work into a cliff beside a rock cut... the entrance to the Johnson Canyon Railway Tunnel!

As we get closer and closer to the tunnel entrance, we notice some wooden and steel features sticking up near the roadbed. From the older photos I believe we are walking over the site of the original trestle. It would appear the bridge was left intact and fill placed all around it. We gaze back down the canyon for one last glimpse before we enter the tunnel. We have traveled 2.4 miles from the FR6 intersection to reach the tunnel entrance. GPS coordinates for the tunnel are 35o 14.820'N, 112o 20.038'W.

The west entrance to the tunnel shows some of the stone mason's skills. There are signs of erosion near the entrance, but no major obstacles. As you walk into the tunnel, the steel boilerplate that replace timber shoring after the 1898 fire is very evident. The tunnel gently curves to the left and is only about 400 feet long. The relatively short distance allows sufficient light to pass into the tunnel such that flashlights are not a requirement.

The east entrance also has some fine masonry work. The keystone also has an inscription we can't quite make out. Again there are signs of erosion near the entrance, but no major obstacles.

We carry on up the Johnson Canyon as it rapidly narrows. A dry fall is evident as we reach to top of the plateau. There are pools of water trapped along the rocky bed. The base of the dry falls seems to offer some of the best colours of the day. Above the dry falls a Ponderosa Pine forest dominates the landscape. We are 3.1 miles from the FR6 trail head and decide this is a good point to turn around.

Summary: The Johnson Canyon Railway Tunnel Trail provides an interesting and unique glimpse into our railway heritage. One of my hiking adventurers had significant surgery during the summer and we used this hike to test his recovery. The abandoned railway bed provided an obstacle-free route in a relatively isolated area. I'd say it was the perfect choice to help get him reacquainted with hiking again. Enjoy!

    To hike
    From Phoenix: Take Hwy I-17 north 140 miles to Flagstaff. At the junction with Hwy I-40, take the Los Angeles exit and continue west. Travel past the town of Williams until you reach Welch Exit 151, about 44 1/2 miles from the I-17 junction.

    The pavement ends when you cross the cattle guard and head north along FR6. As the Forest Road bends towards the east, you will join a very old section of Route 66. There is signage near the junction indicating "Old Hwy 66 Mountain Bike Route". As I peered back to the west from Mike's Jeep, I could see two hard-tails moving rapidly down the valley towards Ash Fork. This old section of Route 66 forms a straight line east and west.

    FR6 will soon split off north about 1 mile from the 1-40 exit as Old Route 66 continues along an easterly heading. Continue along the Forest Road in a northerly direction about 1 mile as it dips into a wash. This is Johnson Creek. I was surprised to see no water flowing in the creek, especially since my daughter reported torrential rains in the Flagstaff area the week before.

    About a 1/4 mile from Johnson Creek as you reach the top of the rise, there will be a large sink hole visible on the west side of FR6. This is Johnson Crater, approximately 2 1/2 miles from the I-40 exit. I found conflicting information suggesting this feature is an impact crater and not a sink hole - we'll let the geologists decide this one!

    Travel another 1/4 mile from Johnson Crater along FR6, just before a cattle guard, you come to a cinder roadbed crossing east-west. This is the ghost-town settlement of Welch Station and the abandoned Santa Fe rail line leading to the Johnson Canyon Railway Tunnel.

    My GPS noted 210 miles traveled from my home in Ahwatukee to the trailhead near the abandoned railway crossing at FR6. Travel time was just under 3.5 hours including a stop in Williams for gas and refreshments.
