Plateau Potato Lake

PLATEAU POTATO LAKE

Potato Lake Tank on Anderson Mesa

Roughly thirty minutes south of the summer hiking magnet of Flagstaff, is a quieter but no less attractive trekking destination.

The basin of Potato Lake on Anderson Mesa

The Plateau Lakes on Anderson Mesa offer respite from crowds in an under appreciated landscape replete with quirky geological features.

Forest Road 82D near Als Lake

The Plateau Lakes Region in Coconino National Forest is anchored by Mormon Lake—Arizona’s largest natural lake.

During years with lots of precipitation, the lake can span an area up to 12 square miles.

But that’s the exception, not the norm.  Mostly, it’s a scenic yet mucky wetland of puddles and swales that still manages to attract wildlife and support a fringe of water-loving vegetation.

It’s also the mother ship per se for dozens of smaller natural water pockets, wildlife waterholes and created lakes that orbit its massive basin.

Geologists describe the Plateau Lakes as naturally occurring bowl-like depressions formed by various tectonic events that resulted in slumps and sinkhole features in the volcanic landscape.

Junction FR82D and FR9484D

Spread across the flatland like pock-marks or lunar craters, some are no larger than a kiddy pool while others rival football stadium proportions. Like Mormon Lake these hollows vacillate between weedy swamps and shallow pools that evaporate entirely in times of drought leaving behind crop-circle-like impressions. 

Entrance to Potato Lake

Hiking to the Plateau Lakes can be done by hopping on the Arizona National Scenic Trail Passages 29 and 30 which skirt by several, or by using a network of rough dirt roads that traverse the mesa. 

Typical scene on FR9494D

One interesting destination is Potato Lake.  Don’t be confused, though. This is a different animal from the watery, crawdad infested “solution depression” (geology speak for a kind of sinkhole) Potato Lake off Forest Road 300 (Rim Road) on the Mogollon Rim near the community of Pine. (Read the POTATO LAKE strory on this blog).

The easy hike to "Plateau Potato Lake” uses three easy-to-navigate dirt roads. Beginning on Forest Road 9117F, the trek heads east for 0.4-mile to where it meets the fenced edge of Post Lake—another Plateau Lake.

A strom brews over Als Lake

The rocky two track then bends north onto the mesa and merges into (unsigned) Forest Road 82D. 

Anderson Mesa is a mostly flat, windswept expanse dotted with junipers and intermittent plots of Ponderosa pines.

San Francisco Peaks seen from FR82D

The airy expanse is criss-crossed with draws and canyons that disrupt exposed grasslands favored by pronghorn.  The mesa is surrounded by volcanic mountains that churn up weather, which means it’s almost always windy here. 

Post Lake

At the 1.3-mile point, views of  8,463-foot Mormon Mountain to the west and 12,633-foot San Francisco Mountain north of Flagstaff stand out over Als Lake, another Plateau Lake with hit-or-miss water levels. It’s worth mentioning that even when bone dry, the footprint of these ephemeral lakes are often lush with wildflowers and knee-high grasses.

Storm over Potato Lake Road

Past the lake, the road meanders through fragrant woodlands dominated by junipers until it comes to a fork where FR9484D spins off to the right. The road, which is also known as Potato Lake Road is signed, but the numbers are barely legible. At this juncture, FR82D continues a half-mile north to one of the most well-known Plateau lakes—Deep Lake.

It’s worth a side trip on the way back. (Check out the DEEP LAKE story on this blog).  FR9484D continues through more juniper-shaded terrain with chunks of basalt strewn about the rusty soils.  The route meets a junction with FR9119W at 2.8 miles. FR9119W heads left and circles Potato Lake, but this trek continues straight ahead on FR9484D.  After another 0.2-mile, a stand of thick greenery of pines, firs and oaks herald the entry to Potato Lake.

Passing through an aboreal archway, the road opens up to views of the sprawling lake. In early June 2026, the lake was dry, but adjacent Potato Lake Tank contained a basin of residual muddy water.  Built into the south edge of the lake with an earthen dam, the margins of tiny waterhole showed signs of wildlife activity.  Elk, deer, waterfowl, raccoon and coyote tracks sunk deep into the moist muck signal it’s time to turn the hike around and leave the precious water to the winged and furry forest residents.

Pine Loop

PINE LOOP

Mazatzal Mountains from Lower Pineview Trail

When asked what passage of the Arizona National Scenic Trail is the “best” one, trail users are quick to state that it’s the one you’re currently on. 

Pine Loop uses AZT Highline Passage 26

For those who have trekked the entire 800+-mile non-motorized route that runs from the Mexico border to Utah, the oft repeated refrain precisely sums up the experience.

Highline/Arizona Trail

Traveling south to north, the trail’s 43 Passages move through wildly diverse terrains. 

Highline/Arizona Trail

Deserts, mountains, riparian corridors, canyons, chaparral, grasslands, valleys, alpine meadows and coniferous forests. So, it’s easy to understand why naming a favorite is an impossible ask.

Mogollon Rim from Lower Pineview Trail

 

But for hikers, bikers and equestrians looking to sample the trail without committing to days-long backcountry hauls, a special bias must be directed at the Highline Passage 26.

Lower Pineview Trail

As the last Passage in the Central Arizona zone, in Tonto National Forest, the 23.9-mile single track marks the transition from arid desert mountains to Arizona’s woodsy high country.

Community of Pine below the trail

It’s also one of the more approachable Passages with several trailheads, connecting trails and access points.  Treatable water is available at several springs and creeks along the way.

Arizona Trail/Pineview junction

A popular family-friendly day hike option that’s doable spring through fall is the Pine Loop. Starting at the Pine trailhead north of Payson, the loop uses the Arizona Trail/Highline, Pineview, Lower Pineview and Pine Canyon trails.

Pine Canyon Trail

The well-signed hike starts out on the Arizona Trail, which shares space with the rerouted Highline Trail. This lower elevation side of the Passage features an interesting hybrid vegetation zone where cacti, yucca and agaves make their last stands as the dominant plants among oaks, junipers and Ponderosa pines.

Pine Canyon Trail

  The loop follows the AZT/Highline Trail for one mile to the Pineview, Lower Pineview junction.  Nearby, a large information kiosk marks the spot.  This is where the loop departs the AZT and heads west on the Lower Pineview Trail. (For a longer option, go north on the Pineview Trail and follow the signs.

The Pine Loop is well signed

This adds roughly a half-mile and 200 feet of elevation to the loop). 

Pineview Trail

Lower Pineview serves up some great views of the Mazatzal Mountains to the south, the craggy cliffs leading up to the 700-foot escarpments of the Mogollon Rim and glimpses of the community of Pine.

Map of the loop

At the 1.5-mile point, the loop swerves left onto the Pineview Trail that hangs on rolling foothills studded with junipers and scrub oaks. After less than a half-mile, the loop picks up the Pine Canyon Trail heading south.  Now, the route is shaded in tall pines as it winds through gullies and drainages before ending back at the AZT/Highline Trail where the loop concludes with a backtrack to the trailhead.

Pine Trailhead 

While short in length and only mildly challenging, this scenic little loop gives a concise tour of a major shift point on the Arizona Trail and might also tempt those just sticking their toes into the world-class trail to explore deeper and maybe discover their own “best” parts. 

LENGTH: 2.9 mile loop

RATING: easy

ELEVATION: 5,362 - 5,692 feet (525 feet of accumulated elevation change)

GETTING THERE:

From Payson, drive 12.6 miles north on State Route 87 to the turnoff for the Pine Trailhead on the right. Roads are paved all the way.  There’s a restroom but no other facilities. Restaurants and services are available a short drive up SR87 in the community of Pine.

Rock Bottom Road

ROCK BOTTOM ROAD

Schroeder Tank

Forest Road 9392E appears to go nowhere.  It’s only vaguely on the Coconino National Forest maps and, on the ground, there are no signs to provide clues. While this is pretty common for the many miles of 4x4 backroads on forest lands, the diffuse mystery about roads that weave through Willow Valley is what makes them  particularly inviting for hikers.

Gate on FR93B near Schroeder Tank

That’s because they have a distinct “soft wild” air about them—out there but with their rough edges tamed by weedy two tracks that seem to always intersect with primary or secondary, signed routes.

Where Forest Road 9369H heads downhill

 

Pine shaded and just far enough from the pavement for a secluded high country escape, Willow Valley on the Mogollon Rim south of the community of Happy Jack, is rife with primitive camp sites and points-of-interest.

Forest Road 9369H

While most of the dirt roads are open to motorized travel, exploring on foot is the best way to savor details that make this area special. 

Yellow Salsify bloom June - September

The landscape is a mass of scattered oak glens, sunny meadows and forests of soaring Ponderosa pines punctuated with corrals and water tanks that attract wildlife and grazing domestic cattle.

Entry gate for FR9369H and FR9392E

Resident deer, wild turkeys, elk and Great blue herons are easy to spot while traveling quietly among the trees. One exploratory hike to try is a two-pronged trek using enigmatic FR9392E and signed routes FR93B and FR 9369H. 

Forest Road 9392E

The trek starts at a dirt pullout where a barely legible road sign across from the Bar D corral complex marks FR93B. Heading north on FR93B, the rocky, rutted road passes through pine woodlands to where it meets Schroeder Tank at the 0.3-mile point.

Kaibab pussytoes bloom May - July

The oblong created water hole sits off to the right within a ring of Gamble oaks and fields of Rocky Mountain irises. 

The split for FR9369H and FR9392E

To get to the water, pass a  barbed wire gate (close it and all gates behind you) and follow a faint trail to the entry archway.  Stealthy visitors might spy a Great blue heron, ducks or tiny birds diving for insects swarming over the tank’s surface. 

Rock Bottom Tank

Beyond the tank, at the 0.7-mile point, another wire gate on the right marks the entrance to FR9369H and 9392E.

Rock Bottom Tank

True to the mystery theme of this hike, it’s just one road and  it’s not signed.

Sego lilies bloom May - July

About 0.2-mile beyond the gate, the road splits.  Lo and behold, there’s a sign for FR9369H, which swerves left.  The unsigned spur on the right is 9392E.  This hike uses both roads as out-and-backs. 

Entry to Schroeder Tank

Schroeder Tank

I chose to follow 9392E first. It’s an easy half mile walk to a faint road heading off to the left where the berm of an earthen dam is visible a few yards in. 

Rocky Mountain iris bloom May - September

This is Rock Bottom Tank, another water catchment and wildlife magnet. Surrounded by a leafy fringe, the reedy pond reflects open sky and fosters wildflowers clinging to its grassy banks.  A rough hewn hunter blind on the berm straddles an arc of pines.  FR9392E, which I’ve dubbed Rock Bottom Road, continues on for another 0.3-mile, dwindling into nowhere near a fence line. (My GPS indicated that it eventually connects back to FR93B, but, I didn’t see where).  Backtracking to the signed FR9369H junction, the mile-long hike on the H road is pretty but unremarkable up to where it passes yet another gate and begins a 200-foot drop to, well, as advertised—nowhere.

Chaparral fleabane bloom May - October

But someplace not on the maps. That is, the junction with FR93B—-the road you came in on. Head left to make a loop that adds 2 miles to the hike, or just backtrack like I did. Either way, simple hikes like this one muddle the concept and appeal of nowhere. Depending on how you perceive it, nowhere can be anywhere. And everything. It’s all in the mindset. 

trailhead

LENGTH: 6.4 miles for the two-part hike as described here

RATING: moderate

ELEVATION: 6,876 - 7,075 feet (1,102 feet of accumulated elevation change)

GETTING THERE:

From Flagstaff, go 42 miles south on Lake Mary Road (County Road 3) to Forest Road 93 on the left past milepost 302 and signed for Willow Valley Dam. Follow FR93 0.8-mile to Forest Road 93B on the left across from a corral complex. There’s a faded road sign next to a Ponderosa pine. Park in the pullouts along the road.  FR93 is maintained dirt suitable for most vehicles up to the trailhead. There are dispersed campsites along FR93 but no fees or facilities.

Railroad Spring

RAILROAD SPRING

Swale at Railroad Spring

During Arizona’s late 19th-to-mid-20th century logging heyday, railroads ran through thick Ponderosa pine forests hauling woody loads to lumber mills in Flagstaff and other Northern Arizona towns.

Gate near Fulton Canyon Tank

Some of the old railroad grades have been decommissioned and either turned onto popular Rails-to-Trails paths like the Peavine Trail in Prescott and Railroad Grade in the White Mountains. 

The old railroad grade

Others have been incorporated into hiking routes like the Arizona National Scenic Trail.

Leftovers from a logging railway

Still others were unceremoniously disassembled and left to decompose adjacent to backwoods roads and rangeland.

Rocky Mountain Irises bloom May - Sept

While the remains of many old railroad grades are little more than scattered cinder beds, rock walls and rotting railroad ties, some retain remnants of life on old timey logging trails.

Start of the railroad grade segment

A few miles south of Mormon Lake, an unassuming dirt road leads to a fading stretch of scrapped railroad and a spring site. 

Fulton Canyon Tank

The short hike to Railroad Spring begins on Forest Road 9488K, moving easily into the pine woodlands of Coconino National Forest.

Spring box at Railroad Spring

The first 0.8-mile of the rough road is open to motorized vehicles, but where the route meets the shallow pocket of Fulton Canyon, a gate bars entry to all but foot and horse travel to protect sensitive soil, prevent the spread of invasive plants and preserve wildlife habitats. 

Railroad Spring

Beyond the gate, Fulton Canyon Tank, a glassy created water catchment, sits off to the left. 

Spring water flows over the railroad grade

The road gets much more rocky as it heads downhill to where it meets a fork at the 1-mile point. Take the left fork and then an immediate right at a bright yellow sign in front of boulders barring motorized travel. This is the entrance to the old railroad grade. 

Swale at Railroad Spring

Strewn with cables, ties and rusty nails, the disintegrating track parallels a green swale. (Leave all artifacts as you found them!). A few yards in, a slick curtain of tricking water spills over the track. 

Western Dog Violet bloom May - July

The spring water issues from a culvert-like structure built into a slope. Just across the track, a huge spring box made of concrete and native stone sits above the swale, metal pipes barely dripping moisture into the grassy channel.  Nearby, a pair of concrete water troughs hint at former livestock runs in the area.  Both were bone dry. 

Troughs at Railroad Spring

Even with the spring’s meager issue, the swale is a lively, lush natural drainage rife with irises, violets and swarms of butterflies. Tiny ponds and rivulets ramble through the mini wetland. It’s a beautiful place as well as an important resource for wildlife and native vegetation.  Beyond the troughs, a faint road heads uphill to the left.  A short walk through fragrant pines and wildflower meadows leads to a log fence and the junction with the Mormon Lake Passage 29 of the Arizona National Scenic Trail.

Arizona Trail Passage 29

The junction makes for a good turn around spot, otherwise, for a much longer hike, consult the Arizona Trail website (https://aztrail.org/) for how to continue on to Mormon Lake Village (north) or Happy Jack (south).
