Emerald Peak
Yoho National Park, B.C.
August 4, 2012

Distance: 10.3 km
Cumulative Elevation Gain: 1280 m

In Snowshoeing in the Canadian Rockies, Nugara describes a terrific route up Emerald Peak along with a fast descent, but why wait until the mountain is buried under snow? We wanted to do it now, in the summer.

Dinah and I hiked up Hamilton Lake trail almost to the lake. About 350 m before the lake where the trail runs downhill, we started up the slope. Being rife with loose shale and dense bushes, it may not have been the best place, but we didn't want to stay on the trail and lose elevation. (From what I've heard afterwards, it's probably easier to go all the way to the lake.)

After some steep climbing and bushwhacking, we angled left and popped out onto an open slope (296004). From there the way was obvious: on our right, a corridor between rock slabs and forest led to the ridgeline.

Once on the ridge, one can hike to the top of the false summit or not, but it's a good place to view the start of the summit ridge, a rocky backbone leading to the summit 400-metres away. And from the false summit, it's easy to discern the notch in the ridge, an obvious place to begin the traverse. This wasn't a ridgewalk. Enormous boulders lay jumbled on the ridge and while fascinating to behold, they compelled us to scramble at times, although nothing difficult or exposed.

After passing some pinnacles next to the notch, the next scene jarred us. Towering rocks appeared to block the way. At first glance, it looked impossible to proceed, but on closer inspection, it seemed merely hopeless. We could continue by dropping down into a chasm between the rocks, but it would leave us farther below the sheer rock. We would need a miracle to get to the next ridge section. So I went looking for a miracle.

I dropped down a few metres into the chasm. In the confines of the chasm, loose shale clattered underfoot and the walls loomed well above me on either side. I called Dinah to come down. Even if the chasm dead-ended, it was pretty cool to see.

The chasm, maybe 50 m long, ended in a shallow cave, but I went ahead anyway. And that's where I found our miracle. At the back of the cave, going straight up, was a tunnel! With my pack on, it was a tight fit, but I squirmed up the shaft, a 3-metre climb. After crawling out of the hole, and after a bit more scrambling, I planted my boots on a huge flat rock, actually part of a humongous fragmented boulder. From there I got my first view of the summit. After a few minutes of easy scrambling, Dinah and I were standing on top of Emerald Peak.

We spent several minutes taking pictures and looking around before we turned our attention to the descent route, a broad, steep avalanche slope under the summit. This corridor was so utterly straightforward, it could be followed blindfolded, although I don't advise it. As an ascent route, it's little more than a steep hike, but the loose rock made it tedious.

We scooted down the rubbly slope just below the summit and then picked our way down the steep avalanche slope, looking for fast scree to descend while aiming for the azure waters of Emerald Lake far below. We continued dropping down until we reached a fork 400 m above the lake. The avalanche slope, dense with scrub, continued on our right, but on our left a vegetation-free drainage beckoned. We took the drainage.

Coming down the avalanche slope our boots often skidded on the loose rock, but we fared no better in the stony drainage. We took our time, careful not to twist an ankle. Eventually the drainage flattened and then disappeared, ending in a flourish of magenta fireweed flowers just before Emerald Lake trail. Our descent, even with a ten-minute, mid-slope break, only took two hours. We strolled 400-m along the paved path to the parking lot. While threading through the throngs of tourists, most of whom would probably not even step off the path, Dinah and I felt a bit smug just having climbed Emerald Peak.

I thought we were blocked, but after dropping down into a chasm on the right we found a tunnel.

Looking down the tunnel we climbed up

We came out on a flat rock fragmented by a metres-deep fissure that required jumping across. You can't see it here, but the tunnel exit is just a few metres behind me.

From the flat rock we saw the summit for the first time

It's an easy scramble to the summit (note the flat rock behind)
