Mount Charles Stewart SE2

On 17 August 2025, Rafal (Raff) Kazmierczak invited me to join him for a sufferfest ascending Mount Charles Stewart's southeast outlier, SE2, near Canmore, Alberta.  Raff probably got the idea for this trip from either Devan Peterson or Ephraim Roberts who separately scrambled up the outlier earlier in the spring.  Although technical difficulties are few, the ascent entails a long approach via Cougar Creek and a soul-sucking grovel up a steep gully on the south side of the outlier.  Admittedly, I did zero research for this trip and had no clue about length or elevation gain.  Raff estimated that it would probably be about a 10-hour day, but he also neglected to take into account that he was dragging my sorry old butt with him!  In any case, I welcomed the opportunity to spend a long day catching up with Raff since we had not done an outdoor trip together in quite some time.

Starting from the Cougar Creek trailhead (51.08664, -115.32649), Raff and I hiked the wide trail along the creek for about a kilometre before climbing over a dam that was constructed in the wake of the historic floods of 2013.  On the far side of the dam, we settled into a long and often tedious walk up Cougar Creek which included numerous annoying crossings and a lot of the same monotonous scenery.  About four kilometres past the dam, we turned left to go up a side drainage with much of the same characteristics as Cougar Creek but drier.  We eventually reached a split where we veered right and began climbing a gully which is deceptively steeper than it appears.  The gully rises about 600 vertical metres--nearly half the elevation gain of the entire trip--in a little over a kilometre.  Raff was much more adept at scrambling up the loose rubble here than me, and he seemingly zoomed right up the gully without breaking a sweat.  To be honest, I am probably getting a little long in the tooth for this sort of scrambling by brute force, and as such, it took me a good three hours to muddle my way up the gully.  By the time I topped out at a high col, I was pretty spent and could barely keep my balance as I plodded up the remaining easy terrain to the high point of the outlier.  Raff had already been waiting patiently there for quite awhile, but despite the lateness of the day, he was not in any hurry to descend and allowed me to take a half-hour break to recharge myself.

When we finally commenced our descent, Raff and I simply backed out the way we came.  The gully had a few sections we could surf, but mostly it was just a long, knee-jarring stumble down ankle-breaking rubble--not fun!  Once we returned to the split, we could relax a little since we had put the worst part of the whole route behind us, but that did not make the remainder of the descent any shorter or less tedious.  As we descended the rest of the side drainage, it felt like it would never end.  The subsequent march out Cougar Creek was similarly long-winded, and although our growing fatigue certainly slowed us, I think we were a little more efficient with all the creek crossings on the way out.  After stumbling back to Raff's car at the trailhead in the dark, we drove to the A&W in Canmore for a late dinner before heading home.

A big dziękuję bardzo goes out to Raff for doing all the driving on this day.
Looks like a new ski slope to try in winter! Raff approaches the new dam which is supposed to mitigate future flooding along Cougar Creek.
You should be able to spot Grassi Knob, Ship's Prow, Mount Lawrence Grassi, Miners Peak, Ha Ling Peak and East End Of Rundle. On his way up the dam, Raff is enjoying the view of familiar peaks across the Bow Valley.
This climb is apparently rated about 5.10...if that means anything to you! Raff pauses to watch some rock climbers scale a cliff.
I actually slipped and soaked my feet early in the trip, but they dried out fairly quickly. Continuing up the canyon requires multiple crossings of Cougar Creek.
I really dislike long tedious approaches up dry creek beds! A little more than five kilometres from the trailhead, Raff turns left to go up a side drainage.
I wonder if the left-hand gully would've been better...I'm never going back to find out! Raff takes the right-hand gully at a split about 1.7 kilometres up the side drainage.
And it just keeps getting steeper and steeper and steeper... Raff scrambles up some water-worn slabs as the gully gets steeper and begins to narrow.
Ugh, I'm kinda done with doing soul-sucking scree slogs like this... Raff begins ascending the steepest and loosest part of the gully.  At this point, there is still another 500 metres of elevation gain remaining in the ascent.

Kind of a secret valley here that I will probably never venture into...

The col at the top of the gully grants far-reaching views to the north.

 

I felt wobbly ascending this final stretch! The remainder of the ascent is a gentle plod up a broad ridge.
Was it worth it? Hmmm... Raff and Sonny stand on the high point (2653 metres) of Mount Charles Stewart SE2.
Actually, Raff had quite a few sips! Hope he's okay to drive when we get back to the trailhead! Raff takes a sip of Fireball Cinnamon Whisky found in the register container (courtesy of Ephraim Roberts).
More than 26 years since I was up there! Mount Fable sticks up like a sore thumb on the southeastern horizon.
Lady Mac is lower than SE2 but way more enjoyable! Mount Lady MacDonald (centre) is technically just another outlier of Mount Charles Stewart.
Somewhat easier going down, but it's still no cakewalk! Raff descends loose rubble in the same gully he came up.
From here, we still had another 4.5 hours to go before reaching the trailhead...ugh. Raff still faces a lengthy and tedious descent ahead of him.
Not recommended...there are much better scrambles to do in the Canmore area. Total Distance:  22.7 kilometres
Round-Trip Time:  12 hours 29 minutes
Cumulative Elevation Gain:  1294 metres
