South Sister via East Buttress
June 24, 2018
Coordinator: William Strycharz
Summit Altitude: 10358 feet
Elevation Gain: 5000 feet
Round-trip Distance: 13 miles
Excursion Time: 13 hours (car-to-car)
This is "not" the easy south side route up South Sister!
This is a very strenuous and steep alpine climb with crampons, ice axes on a rope team.
The East Buttress is a large feature on South Sister rising out and above Green Lakes. I will only attempt this route if it is snow covered. If we get to the East Butt and it is bare we will climb the Lewis Glacier to the South Side route to Summit. The Lewis Glacier is a fairly benign glacier but we will still be on a rope team for safety crossing it.
Meeting Time: 7am
Meeting Place: Green Lakes Trailhead
Route: Green Lakes trail to Green Lakes ele. 6560'.
We will turn left up the creek flowing from the Lewis Glacier. At the toe of the Lewis Glacier ele. 8,000' we will turn right up the East Buttress. This steep snow slope is our crux. On the East Butt we will have 2,000' of steep snow climbing to the safe saddle between the East Butt and the Summit Crater Rim. Once at the saddle it is an easy 500' ele. stroll to the summit rim. The crux is a one way trip up. We will not descend our ascent route.
Our descent route will be the normal south side route but we will turn left at the Lewis Glacier then traverse and descend it to Green Lakes and our exit trail. Post climb-Burgers and Beers at my truck at the trailhead!
Please be comfortable on steep slopes.
Please have climbed Mt. Hood previously or an equivalent steep route in the Cascades.
