What elevation did you reach? I can still hike a steep ascent ok but unfortunately my knees give out when starting down. Leads to some very awkward and potentially funny to watch descents.
It was quite a few years ago and I walked up to the glaciers, an easy walk, and lower down, into a very deep canyon eroded in the south side. Walking along one of the old lahars on the east side was a good way to appreciate their power. At this point some twenty five years later, I’d have to look at a map to get elevations and place names.
