The ski decent from Camp Muir can be done year round. The slog up the Muir snowfield from Paradise to Camp Muir is a little strenuous. Camp Muir is a base-camp for parties setting out on summit climbs.
The first picture looks into the serac of the Nisqually glacier.
Camp Muir tops out around 10,000'. From here, you will see Mt. Adam's due south, and Mt. Saint Helens to the southwest.
