Walker Lake Rim

WALKER LAKE RIM

View from the rim of Walker Lake cinder cone

Maybe it’s a lingering mood in the ether that hints at an acrid, nose-tingling whiff of molten earth or the smattering of solidified lava blobs that surround its rim that makes hiking Walker Lake such a visceral experience.

Walker Lake on August 5, 2026

Sitting near the core of the San Francisco Volcanic field, the extinct cinder cone volcano is referred to as Walker Lake because of the ephemeral water that collects within its crater.

Kendrick Mountain seen from Walker Lake

The San Francisco Volcanic Field is spread over an 1,800 square mile slice of the Colorado Plateau centered around the city of Flagstaff. 

Parry Bellflower blooms June - September

It has been a geologically active area for millions of years and has produced over 600 volcanic features over the landscape.

View from the east rim

Basically, every observable mountain and hill around Flagstaff is of volcanic origins.

Overlooking a volcanic landscape

The last volcanic event that happened about 900 years ago formed Sunset Crater and its adjacent lava flows.

The rim loop trail

Walker Lake isn’t the biggest or most spectacular volcano in the mix, but what catapults it from a one-in-600 minor lump on the landscape to one-in-a-million hiking destination is its serendipitous location. Imagined or not, the scorched-earth visceral feel of the short trail that circles Walker Lake captivates the imagination and drives the narrative of walking on the eroded rim of a cinder cone. 

Aspen sunflowers bloom July - October

The trail is an excellent platform for viewing several types of geological features that rise out of the sprawling plateau highlands of Northern Arizona. 

Primitive footpath to Walker Lake

The trek into this volcanic world begins on a closed road that brushes past an aspen protection area where wire fencing shields the iconic mountain trees from browsing animals so they have a chance to mature. 

Aspen exclosure area 

At the 0.3-mile point, the hike continues behind a large sign that reminds that motorized travel is prohibited in the area.

Lake viewed from the south rim

A short uphill walk on the wide road ends at a 3-way junction and the beginning of the rim loop hike. The trail becomes a slender path as it crawls up over the crater’s south brim.

Humphreys Peak seen from the crater's south rim

Soon, the massive profile of San Francisco Mountain and 12,633-foot Humphreys Peak— a stratovolcanoes that had at one time soared to over 16,000 feet— comes into view. 

Torrey's crag lily blooms in August

The lava domes of the Hochderffer Hills (9,152 feet) and the White Horse Hills cinder cones (9,065 feet) lap around its base.

Looking north from the crater

At several points, first glimpses of the internal crater lake peek through tall pines and a jagged lip of basalt. The trail swings eastward to emerge on the rim’s high point where amazing vistas fill the view frame. 

Arizona pea blooms May - October

Rangeland below is dotted with homesteads, pine glens, stock tanks and the faint scribble of the Arizona National Scenic Trail that skims the mountain 400 feet below. 

Beginning of the uphill hike

Through breaks in the fringe of Douglas firs and Ponderosa pines, views stretch all the way to the Painted Desert. As the trail moves north, 10,418-foot Kendrick Mountain looms large.

Far-reaching vistas

This hill that’s popular with hikers is a complex mix of lava domes and lava flows that built up over millions of years. Farther out, the lumpy profile of 8,215-foot Slate Mountain sits on a hazy horizon.  Interestingly, there’s no slate on Slate Mountain. 

Common silverweed blooms May - August

The complex lava dome volcano is a conglomerate of metamorphic rhyolite, sediments and magma flows. Also on show is 8,864-foot Saddle Mountain another hill of volcanic origins with a hikable road to its summit.

The 3-way junction

The rim loop trail then descends on slippery, rocky tread, landing back at the 3-way junction.  To visit the crater lake up close, follow the middle road and primitive footpaths into the bowl-like depression. Ringed with conifers and fields of wildflowers, the “lake” vacillates from soggy bog to substantial ponds depending on snow melt and monsoon rains.  Let it sink in that you’re standing inside a volcano that in the not-so-distant past (in geological terms—a blip) was a fiery fount of lava and molten ejecta.  And, the fireworks ain’t over yet. The San Francisco Volcanic Field is still active which means more eruptions will almost certainly occur in the future.  Whether that happens next week or in a hundred years, the rim of Walker Lake will be an ideal place to observe the show. 

Hike begins on FR9007S

LENGTH: 3.3 miles roundtrip

RATING: moderate

ELEVATION: 8,109 - 8,502 feet

GETTING THERE:

From Flagstaff, go 19 miles north on U.S.180 to Forest Road 151 (Hart Prairie Road) on the right just past milepost 235. Follow FR 151 1.6 miles to Forest Road 418. Continue 0.2-mile on FR418 to the second dirt road on the left which is Forest Road 9007S. FR9007S IS CLOSED TO ALL MOTORIZED USE but foot and horse travel is permitted. There’s limited parking at a turnout at FR9007S—maybe room for 2-3 vehicles as well as additional parking along FR418.  Be respectful of private property in the area and don’t block access roads or driveways.

HIKE DIRECTIONS:

From the FR418/9007S parking spot:

• Hike 0.2 mile to a fork 
• Veer right at the fork onto FR 9004S
• Follow FR9004S 0.1 mile to a large road closed sign
• Hike 0.3 mile up the road behind the sign (still 9004S, though not signed) to a 3-way junction which is the start of the rim loop trail
• Take the narrow single-track on the right which heads up to the crater rim. For reference, the wide central road heads down into the crater and the lake. The path that continues straight ahead is the return leg of the rim loop. 

Little Waters

LITTLE WATERS

Mint Tank

Puddles, ponds, catchments, springs, seeps, tanks. Sometimes they are spring-fed depressions or ravines that capture snowmelt and rainwater.

Meadow near Mint Spring

But in addition to these natural water sources, there are some 3,000 created wildlife waters spread across Arizona’s forests, deserts and grasslands.

Calliopsis bloom June - September

They can be concrete troughs, tubs or most often, small ponds contained by earthen dams that can horde drainage runoff or be filled manually by the Arizona Game & Fish Department’s “lifesaving water program”.

Blade Tank

It’s an expensive, labor-intensive program, but one that’s necessary for wildlife survival in our drought prone state. The waters may be shallow but their purpose runs deep.

Forest Road 124

Not unlike air conditioning, dams and fake lawns, the waters are survival mechanisms—-Arizona style.

Fendler Rose fruits

In addition to providing essential hydration, the waters are great places for hikers to observe wildlife. While many of the waters blend almost invisibly into the landscape, some are easily accessible by way of forest roads. 

Mountain view on FR 124

Take Forest Road 124 for example, where a cluster of waters strung out along its rough dirt track make for an exploratory hike.  The road is located a few miles south of Mormon Lake off Lake Mary Road in Coconino National Forest and has several stretches that are open for dispersed camping. 

Southeast Tank

For an easy wildlife-spotting day hike, begin at the junction of FR 124 and FR 124C which is right about there the road gets too dicy for vehicles without high-clearance.  From the junction, the road heads uphill revealing scant mountain vistas peeking through dense Ponderosa pines.

Wavyleaf thistle boom June - September

At the 0.8-mile point, a clearing that appears on the left spills into the grassy swale of Mint Spring and Mint Tank. It’s a beautiful spot surrounded by trees, Fendler roses and low-growing wildflowers. Flush with water plants, the tank is a magnet for birds—-mountain bluebirds, woodpeckers and ravens are easy to spot for patient hikers sitting quietly among the tree cover.  Just under a mile beyond Mint Tank, Forest Road 9488L veers off to the right. 

Mint Tank

This primitive road leads to Southeast Tank a few yards in. This one looks like an arrested drainage—small and narrow but evidently attractive to elk and coyotes based on footprints observed around its muddy fringe. The third water on the hike shows up at the 2.9-mile point, though it’s not so easy to spot. 

Wright's bluets bloom May - September

Blade Tank is on the left a few yards off the road. Only the well-hidden earthen dam betrays its location.  Little more than a puddle, it sits in a pine-ringed depression at the foot of a gully. Still, the beasts of the wild find it as evidenced by a scattering of bones, feathers and prints. For a day hike, this is a good turnaround point, though several adjacent closed roads that are open to foot travel beckon further exploration.

Mint Tank

For the best chance to see deer, elk, coyotes, raccoons and birds, find a camp spot the head out right at dawn to stake out a hiding place near the little waters.

Trailhead at FR124/124C

LENGTH: 5.85 miles roundtrip

RATING: easy

ELEVATION: 7,370 - 7,644 feet

GETTING THERE:

From Flagstaff go 28.5 miles south on Lake Mary Road (County Road 3) to Forest Road 124 on the left just past milepost 315.  Follow FR 124 for 1 mile to Forest Road 124C and park in the turnouts.  Roads are paved up to FR124 which is maintained dirt suitable for most vehicles, but high clearance is recommended.

Soldier Mesa

A FLIGHTY FOREST FROLIC

Soldier Mesa Tank

There are a lot of birds on Soldier Mesa. Bluejays, hawks, vultures, finches, hummingbirds, woodpeckers and ravens. Lots and lots of ravens. 

A wild turkey feather at Soldier Mesa Tank

For whatever the reason—its proximity above the course of Fossil Creek, a secluded water source or its lightly used location on the Mogollon Rim—the feathered hordes like it here.

Winged buckwheat blooms July - September

Gamble oaks shade FR9362K

It’s not necessary to be an expert bird watcher to enjoy the popular hobby in birdy places like this. With the aid of technology (see links below) and a pair of binoculars, anybody can play wanna-be ornithologist and feather detective. 

It is illegal to collect most wild bird feathers

But before heading out on a bird-spotting expedition, it’s important to know the rules. First and foremost, it is illegal to collect or possess feathers or any other parts from almost all native wild birds in Arizona. The Federal  Migratory Bird Treaty Act protects more than 800 species including most of what flies overhead in Arizona.

Soldier Mesa Tank is easy to miss

The law also means you may not mess with the birds, their eggs, nests, habitats or feathers. This includes anything you may find on the ground.

Watch for raptors over the juniper meadows

A complete set of rules, guidelines and limited hunting exceptions may be found on the U.S Fish & Wildlife Service website. Of course, if you’re already observing the 7 Principles of Leave No Trace outdoor ethics, that pretty much covers it. 

Junction of FR9362K and FR9365K

A mixed bag of woodland types might be a contributor to the large number of species that call Soldier Mesa home.  Dense Ponderosa pine forests, Gamble oak patches, sunny stretches dominated by junipers, agaves and wildflowers and the mucky waters of Soldier Mesa Tank make for prime habitat opportunities.

White prairie aster blooms July - October

It’s also a tidy little hiking destination for wandering and wondering. Forest Road 9362K serves as the hiking route on Soldier Mesa. From the gated entrance on State Route 260, the rough dirt road makes an immediate duck into tree cover of Coconino National Forest. 

FR9362K ends overlooking Horsetank Wash

A short distance in, white chevron tree markers denote where the road crosses the historic General Crook Trail. Woodpeckers appear to favor the tall pines and are easily identified by their bright red caps and noisy tapping. 

White chevrons indicate the Gen. Crook Trail

Continue following FR9362K as it makes a barely discernible downhill crawl. In places, the road splits and rejoins but it's never too difficult to navigate through oak woodlands that attract wild turkey and sparrows. At the half-mile point, the road meets a junction with FR 9365K.

FR9362K is rough and rocky

Veer right to stay on FR9362K.  The next stretch of road moves through patches of open meadow dotted with yucca and cacti.  Hummers, finches and jays flit among juniper branches. At 0.8-mile, Soldier Mesa Tank comes into view off to the right. It’s easy to miss, so stay alert and you might see hawks and ravens circling above the tiny pool.

Agaves thrive among Ponderosa pines

Beyond the tank, the road degrades into a rocky, cracked-earth path, ever narrowing until it fades into scrub and boulders above Horsetank Wash at the far northeast boundary of Fossil Creek Wilderness.

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.

Texas Frog Fruit blooms April - November

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

View of Peaks from FR9484D

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.

Forest Road 82D near Als Lake

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.

Field Bindweed blooms May - September

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 story 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. 

Potato Lake Tank

A storm 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.
