Humphreys Inner Basin (AZ) (June 20, 2014)

Route: Inner Basin Trail, Weatherford Trail
Mileage: ~10.5 miles
Elevation Gain: ~2900 feet

A day after a fun day hiking to the highest point in Arizona, I stayed a bit lower (though not all that much lower it turned out). There is a network of other trails on Humphreys Peak besides the trail that goes to the summit, and one of them heads through the center of the caldera from the ancient volcano.From the summit the day before I could see tons and tons of green, rather unusual for a predominately desert state, and I was eager to see what was in there.

Heading up US 89 to a dirt road turn off across from the turn for Sunset Crater, I followed signs for Lockett Meadow, which is where the trailhead for the Inner Basin Trail is located. The last 3 miles are up a steep, narrow, winding mountain road with no guardrails and is a little rough and bumpy, but despite the sign saying it was not maintained for highway vehicles, I had zero trouble getting up there in my rental car (a sedan). This road is closed in winter and early Spring due to snow, but it was long open at this point of course. There are a large number of campsites scattered around the trailhead area (fee required), and it was a pretty nice looking area. There was no fee for day use parking.

In 2010, there was a massive fire in the lower elevations (the Schultz Fire) around Humphreys Peak, and it was barely stopped before it burned the Inner Basin. Along the first 1/4-mile or so of the trail, there was ample evidence that a fire had been in the area, and one area not far in was almost completely burned out, though the undergrowth had filled back in very nicely already.

In stark contrast to the Humphreys Trail but more like most Western Trails, this trail was gradual, had very few rocks sticking up in the trail, and offered some great walking. Pretty soon it entered some aspen glades, and switchbacked up through them for close to a mile. These woods were absolutely gorgeous, with the tall, straight trunks of the aspens towering high above and everything a bright shade of green aside from the trunks. It reminded me a lot of some of the extensive birch glades one finds in the White Mountains in New Hampshire, except a LOT bigger, and even more awesome! In many ways, this stretch was the highlight of the hike for me.

1.75 miles in, for the next 1/4-mile or so, the trail joins the Waterline Trail, which is really a gravel road that is closed to cars aside from Administrative vehicles. The Inner Basin provides a fair amount of the water supply for the town of Flagstaff, and the Waterline and Inner Basin Trails above this junction provide a way for servicing of the wells to occur. It did mean that I was essentially walking a road for a fair ways, but that was okay.

A well in the heart of the Inner Basin - in one of the large open fields visible from the summit of Humphreys Peak in fact.

Well #9 (picture above) marked more or less the end of the "maintained" part of the road, though the trail continues up the old road bed a ways further. The fields here in the Inner Basin offered some cool views of the surrounding ridge (which of course is the old volcano's rim), along with more aspen fields. Continuing up past the fields, the trail re-entered the woods and began gradually climbing again.

There were lots of patches of snow still in the woods around 10,000 feet and up.

When the old road ended, the trail swung left onto a more typical trail, and switchbacked its way up to its end, at the Weatherford Trail. This had been my goal for the day, but it was still early and I knew I wasn't too far from Doyle Saddle (11,370ft) so I headed up the Weatherford Trail to that saddle. This saddle is the one on the opposite side of Agassiz Peak from Humphreys Peak (if one is really ambitious, you can summit Humphreys Peak from here but I wasn't going that far). I was hoping for some good views from the saddle, but it was mostly treed-in, though the impressive bulk of the summit cone of Agassiz Peak, stretching 1000 feet above, is quite visible from the saddle.

Officially camping is prohibited between Doyle and Fremont Saddles, but people clearly camp here anyway.

I turned around here, though I had toyed with going another mile further up to the saddle where the Humphreys Trail comes in, as it was only a couple hundred more feet of climbing. But, with a couple of flights the next day, I didn't want to over-do it, so I headed down after a short break. The descent was easy. Also, unlike the ascent where I had seen only 2 people, I ran into many people just below the Inner Basin heading on their way into the Basin for exploring. Being a Friday and on what I assumed to be the quiet side of the mountain, I was a bit surprised, but I can also understand the attraction to the area. I would certainly go for a hike in there again!

Of course I had to have one more Aspens shot! This was along the merged Waterline/Inner Basin Trails.

Elevation Gain: 3400ft

En-route to Los Angeles for a business trip beginning on a Saturday, I decided I should take a few days off for myself and made a slight detour to Phoenix, Arizona. 2 hours of driving after landing, I was in Flagstaff, ready for a couple of days of hiking. The next morning, I woke up early (the 3-hour time change works in the favor of East-Coasters!), had breakfast, and drove the short ~20 minute drive to the Arizona Snowbowl, a ski area which shares parking with the trailhead for Humphreys Peak. While on my visit, Flagstaff saw daily high temps in the mid-80s, but being a desert area, it gets quite chilly at night. In fact, at the trailhead at 7:30AM, a couple hours after the sunrise, it was in the upper 30s!

An extra day of acclimation to the elevation would have been good (Flagstaff is at 7,000ft, the summit at over 12,600ft), but I figured by taking it easy I would be okay, and worst case I had another day too. Humphreys Peak once was a massive volcano, standing over 17,000 feet tall, before the side of it blew off long, long ago, leaving a series of peaks along the edge of the old caldera. It rises abruptly out of the plateau surrounding the Flagstaff area and continuing up to the Grand Canyon, and is quite striking as you drive up the highway from Phoenix. You can't miss it from downtown Flagstaff!

Next to the trailhead parking lot

The Humphreys Trail climbs from about 9250' to the main saddle (11,800') between Humphreys Peak and Agassiz Peak, the only other 12,000-footer in Arizona. From there it follows the ridge to the summit, though there are 3 false summits along the way (none require a subsequent descent though, so they aren't so bad). That final stretch along the ridge is above treeline and offers spectacular views in all directions. Below the saddle, the trail was actually somewhat reminiscent of trails in New Hampshire: rocks, roots, and a fairly steady grade after the initial mile. It never got all that steep though, which was good considering the thin air one finds at these elevations. Lots of switchbacks are present, which seems to be the norm in the Western US. Down low the woods are a mix of aspen and some sort of pine, and up high before treeline there are lots of bristlecone pines.

The field at the trailhead was full of these plants

Why yes, that is the trail!

"Hiking off trail prohibited $500 fine". "11,400 ft. No camping above this elevation".

I made pretty good time on the lower 2/3 of the trail before the saddle. While a bit rocky, it was footing quite familiar and the grades were nice. Then, around 11,000 feet, my lungs reminded me that it's a lot harder to breathe at that elevation and my pace slowed dramatically. Coincidentally, that's about the same time the major views start! Hitting the saddle, which is also a trail junction (the Weatherford Trail ends here - it offers a much longer ascent route from the South/SouthEast), I was stunned to see a massive field of green laid out in what was the center of the old volcano. What a view!

Snow, in late June, in the desert, yup!

The trail along the ridge was predictably rocky, but the footing was actually pretty decent, and while the next mile or so gains about 850 feet, it never felt all that steep. There just wasn't any oxygen! Still, slow and steady with ample picture breaks, and before too long I was at the top!

Instead of cairns, they use sticks like these above treeline to mark the trail

There was a snowfield just a couple feet off the trail. It begged to have a snowman made from it. This was all my fingers would permit me to make.

Views were 360 degrees, with Flagstaff to the South, the Painted Desert to the East and Northeast (and a peak way beyond it that I was informed was on the New Mexico or Utah border - I forget which), and the North rim of the Grand Canyon way off to the North was quite visible too. In the immediate vicinity were lots of little volcanic-looking peaks, and the awesome inner basin (the inside of the ancient volcano).

I was the 4th person of the day to summit apparently, and others soon summited shortly after me, with lots of great conversations commencing. I was easily the one from the furthest away (well, I think I may have been the only non-Arizonian up there!)

The heart of the Inner Basin - the bright green is almost all aspens and must look amazing in fall!

The sign had fallen over :(

But that was easily fixed! - US State Highpoint #5 (I'm not really working on that list)

Looking back at the parking lot where the car is waiting

With views like this, plenty of daylight left, terrific temps, and hardly any breeze, it was easy to stay here for quite a while. I signed the register (which was full, so people were signing in margins, corners, and wherever else they could fit), took pictures, ate snacks, drank water (lots of it!), chatted with other hikers, and simply enjoyed the day. A number of the "locals" commented that I couldn't have picked a better day for this. Between the perfect hiking temps, the low winds (apparently 2 days before in town there were 70mph winds!), and the great visibility, I had to agree. A little bit of a breeze actually would have been nice, as with the still air, there were a lot of swarming bugs, but unlike the obnoxious black flies of the NorthEast, these were just swarmers, and not really biters.

Eventually I did tear myself away and headed down, but not before deciding for certain that my hike the next day would be among the trails that go through the Inner Basin and all those awesome aspen glades! The descent was easy, and I was back at the car in good order. Off to the motel for a shower and then out to dinner!

The clouds came out during the descent - how dare they!

A side note on the altitude: normally I would do a bit more acclimation for a hike over 10,000 feet. At no point on this hike did I feel anything more than shortness of breath from the thin air. No headaches, dizziness, or the like. I drank about 3.5 liters of water on this hike, which for me is a lot on a 10-mile hike even in the summer (and the temps were pretty nice for hiking on this one), but I wanted to stay ahead of the game. If I had felt any symptoms, I would have headed down and tried again the next day. But interestingly, after I got back to the car, I proceeded to have a pretty good headache for the rest of the evening. Thankfully I slept it off back in town overnight and was back to 100% in the morning.

About 10 miles and 3400 feet of elevation gain.
