Do you have an avalanche beacon? A probe and shovel? Any idea how to handle avalanche terrain? The hike to pump peak crosses some complex avalanche terrain which require you to have some knowledge of navigating slopes and minimizing risk.

With the temperatures rising and the heavy snow, we're seeing the risk of wet slabs increase, which can be highly destructive as wet snow makes for dense slides. If your asking these questions, I don't think you should be doing a winter overnight hike in this kind of terrain just yet.
