Ptarmigan Peak was the second peak of the day for Jon and I on September 5th 2005. Earlier we had climbed Mount Richardson and now we found ourselves plodding up the scree slopes of Ptarmigan from Hidden Lake. We didn't see any of the mountain's namesake but we did see lots of bear sign on the lower, grassy slopes!
Ptarmigan is an easy scramble and other than a very short bit at the top it is a mere slog up scree slopes that don't seem to end quick enough! The fun occurs right at the top where you briefly have a bit of a ridge to contend with and some slight exposure - nothing to worry about.
As a note, if you're coming to Ptarmigan from Pika I think it is possible to cut up to Ptarmigan from the Pika side-slope before coming all the way down to the meadows. Consult your map and look carefully at the slopes before hand.
