Arizona Trail Passage 34: FR418 to Kelly Tank

ARIZONA TRAIL PASSAGE 34 SAN FRANCISCO PEAKS

Forest Road 418 to Kelly Tank

Aspens and pines on the Arizona Trail Passage 34

An Arizona “alpine start”-the pre-dawn trailhead call for a mountain hike- can be timed by the stars. Basically, if Orion has faded into the dawn, it’s already too late.

It then disappears for a few months before making its summer debut in the early morning hours of August. Visible low on the eastern horizon around 4 a.m., Orion the Hunter signals the hour Phoenix area day hikers must leave the Valley to beat high country monsoon storms.

There are three things to know about summer hiking on Arizona’s mountain trails. First, temperatures will be cooler, but fickle. Second, mountains make their own weather, often churning out thunder, lightning, high winds, and rain after 11 a.m. And finally, being caught on a mountain or in the open during a monsoon storm is a potentially deadly situation.  That’s why it’s smart to follow The Hunter’s lead and head out super early to be off peaks and into safety before noon.

Per the National Weather Service, “When thunder roars, go indoors.” For more lightning safety education, visit:  https://www.weather.gov/safety/lightning.

In addition to staying alive, early morning hiking has many benefits.

The crack of dawn is the best time to observe wildlife and witness the syrupy amber “alpenglow” the sun paints on mountain slopes.

The San Francisco Peaks Passage 34 of the Arizona National Scenic Trail is one worth setting the alarm to experience.  The Flagstaff area favorite runs for 35.3 miles between the Weatherford Trailhead at the south edge of the peaks to Babbitt Ranch in Coconino National Forest.

Along its mostly easy course, the trail cuts through aspen glens, dense coniferous forests, meadows, and juniper-studded rangelands.  The entire passage is hemmed in by mounds and craters of the San Francisco Volcanic Field, an 1,800 square mile swath of the Colorado Plateau with over 600 volcanic features.

Passage 34 rounds the slopes of 12,633-foot San Francisco Mountain ( the Humphreys Peak Trail goes to its summit), a dormant stratovolcano, and heads north through a maze of cinder cones and lava flows.  For a volcano-centric day hike, the segment of the passage that runs between Forest Roads 418 and 514 is a beauty.

The 6.8-mile out-and-back trek begins in a thicket of aspens on the northwest edge of San Francisco Mountain.  An understory of ferns, lupines, and tall grasses lap at the legs as hikers take on the gentle inclines. Within a half-mile, the trail parallels the Walker Lake cinder cone.

Standing at over 8,400 feet, its pine-fleeced crater contains a shallow pond. The swampy pool is not visible from the trail, but a nearby dirt road leads to its innards. To the east, the weathered peaks of the White Horse Hills rise over Deadman Wash.

As this hike approaches its turnaround point at Forest Road 514, the tree cover thins out opening views of  10,418-foot Kendrick Peak to the west and 8,864-foot Saddle Mountain straight ahead. Both have trails to their summits. At hike’s end across from Kelly Tank, an Arizona Trail gate  marks the route’s transition into more arid terrain where junipers, brush and wide-open spaces commandeer the viewscape. Still, the mountain-borne lightning storms that happen on a near daily basis in summer are something to monitor and avoid.  An alpine start helps.
