Skied CB today and the 2 previous days. The snowpack is the deepest I have ever personally experienced there, and from everyone I talked to is essentially all time. Skied inbounds yesterday, it was definitely a bit hard underneath, but with more snow today and in the forecast I'm sure its gonna stay great! Sorry, can't give you any info about the park, everything else was far too fun for me to ever venture over there, though I am pretty sure you need a park pass for the main park. The CB BC is also great right now, check out my blog: http://powdergucci.blogspot.com
for some insights on that.
