what does that even mean?
that said, i do see a lot of comments about how bad heavenly is which are based on misunderstandings and ignorance. a comment like "terrain is better suited to skiers" is based, in part at least, on a lack of knowledge.
Remember, this is a snowboarding forum, and the OP was looking for intermediate and family environment.
My knowledge is based on having been to Heavenly many times over the years...dating from the early-90s to recently.
The top to bottom vertical can only be achieved by accessing numerous roads (i.e. Milky Way Trail, Round-A-Bout, California Trail...heck even the Cat Track trail doesn't hide what it really is.)...hopscotching overlapping lifts without riding one of these roads doesn't get you up or around the mountain...not exactly snowboard friendly..
The total acerage includes areas like Mott & Killebrew Canyons, the area under Galaxy chair, Milky Way Bowl, Ski Ways Glades (which is where about 15% of Heavenly's acreage is buried)...all of which need a substantial amount of snow to be suited for snowboards as opposed to skis...not to mention Gunbarrel and the Face.
Does Heavenly lie? No...it accurately reports that within its permit area, it has a certain number of acres under permit and lists the top and bottom elevation of the area under permit. But that doesn't tell you what lies within the area....
Kind of like expecting powder bowls at Northstar, a lot of groomed runs off the top at Squaw, or all of the terrain within Alpine/Kirkwood to be lift accessible.
Yep, I'm biased...if I'm going to have to work to get to the runs, I'd rather hike off the top of the lift than hike to get to the bottom of the lift, or even between lifts.
