Ben's report was spot on. Road to the 2WD TH: groomed. 2WD to the pearl pass split off: snowmobile and ski tracked by hut-trippers. Turning up for castle: no tracks and a complete cluster until you get high enough on Malamute's south face. Malamute's south face has some avy slopes to compete with. Once above the road and up the 2 headwalls, it is easy peasy. Also went to conundrum and then back up castle. You would be making a truly unwise decision to head down from the saddle given the condition of the snow pack. 18.5 miles RT for Castle and Conundrum.
