Middle Sister (OR)

Bend, OR
Not to be confused with the Canadian Rockies scramble, Middle Sister near Canmore, Alberta, this one is the smallest of the three volcanoes in central Oregon west of Bend. It’s only marginally shorter than North and South Sisters so to me, this group of peaks is considered as three separate volcanoes, instead of one volcano with two sub-summits. The standard route goes up the north ridge and is accessed by Hayden Glacier from Pole Creek trail-head. There’s nothing difficult to get Middle Sister but peak-baggers should aim to combine Middle with North Sister in one push. That’s the plan between Alex and I and we had climbed North Sister earlier in the day.

From North/Middle col we traversed and ascended a broad but flat snowfield to another col immediately at the base of Middle Sister’s north ridge, and then took a break ditching most of the gears. There still appeared to have substantial amount of snow on the north ridge so we had to haul crampons and ice axes, unfortunately. The lower ridge was mostly a class 1-2 hike on a game path. The snow band in the middle was about 35+ degrees but is heavy packed by scramblers. Following the boot paths we didn’t feel the need to use any specialized gear and in short time we were on the summit. The clouds came in and out intermittently and created some dramatic views.
After a while we started the descent. The snow offered neat oppurtunity to boot-ski and so did the scree. In no time we were back to the col packing up gears. Plunging and gliding down Hayden Glacier also took no time and there came one last transition/break at where I ditched the trail-runners. The rest of the hike-out was very boring and tedious but at least didn’t take too long. Our round trip time was under 11.5 hours which was pretty much as expected.
Not doing any unnecessary lingering we drove out to the city of Bend, had a delayed dinner, and then drove to South Sister’s trail-head. And then there came the next day.
