Sundial's Global Warming Arete

Obviously pumped, but exuding his usual calm demeanor, Paul hoisted himself onto the spacious ledge below the final pitch of the Sundial’s spectacular Northwest (aka Global Warming) Arete. He’d just pulled through the slightly overhanging 5.8 “crux” and he looked relieved, stoked, and in need of a rest. The move involves a finger lock and a strong pull without much for the feet, to reach a hidden edge deep in a pod. However, to climb into the pod, you’d need to be 30” tall! Instead, one must stare down the exposure and look for holds above and outside the alcove. Not terribly hard, but a couple notches tougher than any other move on the mostly 5.6 route, also known as Eleventh Hour.

I call it the Global Warming Arete, because even when its 100 F in the city, this airy, shady, northerly climb between 9500-10,000’ stays way cool. I’ve never climbed it without having to put on a layer. Usually, I wear pants and a windshirt the whole way. Who says the Wasatch doesn’t have alpine rock? The Tetons have nothing on this!

Paul Oelerich and I met at the Broad’s Fork / Mill B South trailhead at 6 am and enjoyed the 3,000’, 3-mile approach. We were on the shady west side of the rugged canyon in the coolest part of the day. Sunrise on 11,107-foot Dromedary Peak’s northeast face glowed pink, then orange as we cruised up the well-established path to Lake Blanche.

Named for a pioneer Mormon woman, Blanche is nestled beneath the sharp, 500’ triangle of solid Quartzite that is the Sundial. Her sister lakes, Florence and Lillian, fill glacial-carved basins just to her west. All were “enhanced” by dams built in the depressed 1930s. Shortly thereafter, SLC engineers realized the threat of flood from one of these fragile dams bursting exceeded any value they had, and all such dams in the Wasatch were breached.

Regardless, it is a delightful camping area and, along with Red Pine lake in the Lone Peak Wilderness, it’s the most popular summer backpacking area in the Salt Lake mountains. That means on any hot day in the city you may see 3 parties escaping the heat here. But usually the only inhabitants are mule deer, trout, and non-indigenous mountain goats, ranging the maroon-colored rock slabs above.

Just east of the lake the trail disappeared in a meadow of brilliant yellow wildflowers soaking in the morning sun. Another 500’ of boulder-hopping brought us to the low-point of vertical rock. The first few moves typify the climb: steep and edgy with plenty of holds. Problem is, they are all sloping toward you. In-cut edges are rare. Spice it up with lichen, loose rocks, and tricky pro, and you get the picture. Its adventure climbing, not a well-traveled crag!

The first belay defines the word “ledge”. Its 2’ wide and 5’ long with 100’ of air below and a small roof above. As you sit to belay on the cool stone, your gaze wanders out over Lake Blanche, Big Cottonwood Canyon and the Salt Lake Valley to Antelope Island.

The second pitch starts “slopey,” and then gets easier before ending on a broad, loose terrace. The standard procedure from here is to move 50’ west and climb a wide corner. Instead, I go up and right on decent rock to a belay near the arete. The fourth pitch includes the exciting crux, and sets you up for the final, 100-foot lead.

Before you go up, you have to step slightly down onto a sloping edge with only a mono-digit pocket for hands. Fortunately, this heady move is well-protected, being just below the belay. Then the route climbs a steep, beautiful crack system with good holds. One must resist the temptation to continue up as it becomes 5.9 fingers. To keep it 5.6, follow a sidewalk back west to the arete. Now a small dihedral goes right up the crest for 70’ of quality moves on great rock.

Quartzite gives way to broken Slate / Shale just above the final belay, and the ridge goes horizontal. Its possible to scramble south for a mile and walk off to the west, but several rappel lines to the East are what most climbers employ. The cleanest option is to go south for 200’ and then zigzag down to a solid horn with slings. One rapp of 35 meters puts you on easy ground. A short scree slope leads back to the base.

There is no better way to enjoy the high Wasatch than on the Global Warming Arete. The down hike is in the afternoon sun, but who cares? You’re going with gravity! Now the trail is crowded with day-hikers, sweating their way up. As you step out of their way, you gloat with the satisfaction of having gotten up early, scaled a beautiful arete, and beaten the heat. When the trail crosses the creek just above the carpark, hopefully you’ve cached a few of your favorite beverages in the icy waters. A shady, creekside bench is the ideal place to toast a perfect summer day.

  1. Had a chance to do this climb with UMA. It was spectacular! And oddly enough, even on a hot summer day, it really did get cold on the "gully pitch" shaded by a massive roof. This pitch also had a lot of loose rock that, if released, would funnel down the gully at the belayer, so you've got to be really careful. The fourth pitch is the money maker! The overhanging part really didn't seem that overhanging to me. The crux is actually after that part. Like Tyson said, you've got to move up with nothing but a silly crack, (in which I couldn't find the finger lock), and no feet. Once you're threw, find a good stance and rest! It's pumpy if you're like me and have bad technique. Mike Kaserman made it look so easy. He was static through the whole thing. I don't know how I got through it, but it was sloppy and desperate! Ah, but what a great climb! From there you continue up, turn a corner, and finish up on a nice ledge for the final short pitch. Reaching the top and looking out over the basin gives you an enormous feeling of accomplishment. This is the best view of all 3 lakes! It is also a very interesting view of the trees as they all seem to point in different directions from this perspective, as if they were being filtered by a spherical distortion. This climb is a must do!

Pain and Suffering...Life at Europe's favorite American Crag

Fall in Utah is amazing (as are the other 3 seasons.) But autumn is especially stellar when the yellow leaves of Aspen and Cottonwoods are juxtaposed against a backdrop of red sandstone cliffs. This feast of color is easier to appreciate when you get your feet back on terra firma after jamming them sideways into 2" wide, 100' tall, vertical cracks. This is Indian Creek: a paradise on earth, assuming you like crack climbing; i.e. assuming you like to suffer. But that’s what climbing is when you push yourself out of the "comfort zone:" suffering. Your success is dependent on your ability to suffer. No one actually LIKES it, but some people suffer better than others. These are the climbers who succeed, and everyone gets stoked on that!

Veteran crack-climbers drop their knee away from the crack, insert their foot sideways, and rotate their knee back in-line with the splitter groove. This locks the foot securely in place, making it a solid hold. It also hu…


The South Ridge of Mt. Superior, 11,050', is a classic, mixed alpine route. It starts with a low-angle "apron" leading to a 45-degree Couloir. This connects to the knife-edged rock and snow "arete." After a spectacular summit the route descends the easier East Ridge.
Crunch, crunch, crunch...up the solid spring snow of Suicide Chute. Zigging back and forth with cross-over steps we move efficiently keeping the feet flat and crampon points in the snow. This "French Technique" propels us far up the Couloir in the early morning hours. Sherman keeps his Ice Axe pick facing forward as he belays himself for security on the firm, steep slope.
Ahhh...Sunrise...and we're nearing the col. The snow climbing is just about over.
Keeping the crampons on for the occasional snow step, we find the points work fine even on dry Quartzite. Using the rope for added security we employ "running and fixed belays" on the more difficult and exposed sections.


White Pine Parking Lot, 7,700', one mile below Snowbird in Little Cottonwood Canyon, is THE trailhead for a mega-zone of backcountry ski terrain. White Pine itself is the eastern-most of the 5 skiable gulches that drain into LCC. The forested terrain down low is great for safe, peaceful, and scenic skinning.
Skins come off at the top for blissful wiggling through the fluffy meadows.
Mid-altitude evergreen glades offer wind-sheltered powder on the edges of the more open terrain.
Before venturing onto more committing lines, avalanche danger must be carefully assessed. The guide performs a Compression Test in a snowpit
and decides to open up this tasty poke underneath a rocky point called The Spire.
If the snow and weather are both stable, the bigger lines on Red Baldy (in background between skiers) and Lake Peak become great options.

Below, a skier reaps the reward of his labors with untracked powder on the broad Northwest Face of Red Baldy, 11,170'. Another set of tracks is just vi…
