These peaks are part of the Highwood Range in Kananaskis. Since they're unnamed I refer to them as "Lineham Twin Peaks." (After posting my trip report, Andrew Nugara summited a series of connected peaks in dry conditions starting with Twin Peaks. He calls those peaks "Lineham Creek Peaks.")
From the valley, it appears the second peak can be easily reached via the 250 m connecting ridge. But looks are deceiving. To our disappointment, we were only able to reach the lower peak at GR618951. We couldn't get close to the edge because of snow, but It appeared to be a sheer drop down to the connecting ridge from the first peak. Steep, snow-covered slabs led up to the second peak.
To reach the lower peak, we followed Lineham Creek Trail following the description in Kananaskis Country Guide Vol. 2. We reached the confluence and crossed Lineham Creek after an hour and half. Minutes later, we left the main trail and struck out east on a side trail that followed a semi-forested gully. We left this trail to head up through forest to the ridge, but as we learned on the return trip, it's easier to stay on the side trail. It turns NE and leads to a basin at GR610942. From there it's a matter of following the ridge to the first peak. The ascent took four hours (the descent took 3.5 hours but it was a nice day so we took our time).
There was no cairn and it was far too cold to stay long enough to build one. Maybe the next person up can build one!

The peaks come into view just minutes after starting out on Lineham Creek Trail.
Starting up the ridge
Typical of the ridge terrain
This point could probably be downclimbed easily in dry conditions, but we dropped down
(see tracks on the far right) to get around it.
We had ice axes but never used them.

We skirted below some of the prominences but in retrospect it may have been more
enjoyable to go up and over them.

On the way down we find shelter and take a break.
