The glacier travel is minimal. The glacier is really mellow and almost flat everywhere. Steep snow on Colonial and a couple "steepish" slopes between the glacier and summit on Pyramid and the Stump.
On Pyramid, no ropes needed for the walk up route. Ice ax(for sure) and crampons(if icy) this time of year. Stash some tennis shoes at the end of the approach ridge(before you drop down the gully) for the hike out. You'll thank me later.
The crux of that whole trip is the approach!!!
Water might be scarse between the lake and the glacier.
Oh, BTW. The best approach this time of year is to go all the way to lake and take a trail (one on left of lake and one on right), to get to the top of the ridge. Follow the steep trail on the top of the ridge(no water, I'd save two liters for the ridge, 3 if camping on it) all the way to just before the ridge end (you can bypass some of the humps on trails on the right).
On the last little hump at the ridge end, there is a gully that traverses down and left(rock on the right, trees on the left). This will take you to slopes leading up to the glacier. There is usually running water where the glacier starts.
