Backpacking the Arizona Trail, Passages 31 (Walnut Canyon) & 33 (Flagstaff)
AZT Day 29
Trans-Utah/Arizona Day 36

In the land of Arizona
Through desert heat or snow
Winds a trail for folks to follow
From Utah to Old Mexico

It’s the Arizona Trail
A pathway through the great Southwest
A diverse track through wood and stone
Your spirit it will test

Oh, sure you’ll sweat and blister
You’ll feel the miles every day
You’ll shiver at the loneliness
Your feet and seat will pay

But you’ll see moonlight on the borderlands
You’ll see stars on the Mogollon
You’ll feel the warmth of winter sun
And be thrilled straight through to bone

The aches and pains will fade away
You’ll feel renewed and whole
You’ll never be the same again
With Arizona in your soul

Along the Arizona Trail
A reverence and peace you’ll know
Through deserts, canyons, and mountains
From Utah to Old Mexico
-“The Arizona Trail,” Dale R. Shewalter

Welcome back to Aspen’s Tracks, thruhiking the Arizona Trail from Utah to Mexico.

Flagstaff

After doing a full resupply yesterday to get me through to Pine, where my next box has been shipped, and replacing some gear, including a new pair of boots and new sleeping pad, today started with breakfast with Oscar at Tourist Home, which I wrote about in my last post as one of the best breakfast places in Flagstaff. The weather is going to cool off again in the next few days, dipping down into the 20s overnight.

We encounter Neil Bob, another SOBO thruhiker from Seattle. He’s staying in town the next few days recovering from some IT band soreness. Oscar drops me and my 75(!) lb pack off near the Trailhead and we say goodbye. I hike down the access trail and rejoin the main Arizona Trail, then start south again.

The trail passes through Walnut Canyon, beneath towering cliffs of Coconino Sandstone tinted gray and pink and highlighted with green ponderosa pines. Finally it climbs out and passes through a reroute in a burn area. It looks like the original trail here has been intentionally covered with logs on at least one end, and the reroute is marked with flags, so I’m guessing the reroute is permanent. Just shy of Marshall Mesa Tank I run out of daylight and stop for the night. Tomorrow will start the trek across Anderson Mesa toward Mormon Lake.
