August 19-20, 2000
The group hiked in on Saturday morning from Frog Camp at Obsidian
trailhead under overcast skies but moderate temperatures.
We arrived at Arrowhead Lake around 2:30 p.m. and set up camp.
That afternoon we reviewed crampon usage and self-arrest on an
adjacent steep snow field just south of our campsite.
The upper half of North and Middle Sisters were not visible all
afternoon and as we finally turned in that evening we were concerned
about visibility for summiting the next day.
We awoke at 5:30 a.m. Sunday morning to clear skies and 30 degree
At 6:30 with crampons and ice axes we headed up the northwest slopes
of Middle Sister to pass just to the west of the Dragon’s Back
and up the Renfrew Glacier.
The traverse of the snow field on the north slope had good steps kicked
in and we summited at 11:00 and were greeted on top by climbers summiting
from the south side.
Clear, sunny skies with no wind made the views from the top quite enjoyable.
