Hey that's my video! Haha, just stumbled upon this thread, and figured I would say Hi. It was definitely a dream vacation, and the Virus avalanche was a great board. It floats pretty well, and is a lot of fun in everything I've tried so far. Actually, thanks to Poutanen for your reviews of the board, because it was one of the reasons I ordered it this year. I certainly haven't been disappointed!
In regards to the terrain, about 50% of the video is actually from 2 different runs that we did a few times each. It was indeed mellower terrain, and while we did get to play on a few rollers, hips, etc., we generally avoided them due to higher avalanche risk. It was still great fun on these runs, because it makes you feel like Craig Kelly or something just ripping down from the top of the ridge with big snow-tails behind you.
On the whole the terrain was definitely not mellow or boring, however. Staring about 7:30 in the video we start to get into some steep pitches. At about 10 minutes is probably one of the steepest runs we did, which you can tell by the significant amount of slough and conservative riding. We also did several couloirs that were narrow, some having rocks just below. I also missed a few of the couloirs and steeps we rode due to my GoPro battery dying (which happened every day despite having 2 batteries). At about 18:15 in the video was the second run we did on the first day, and we did several more like this that day. Unfortunately, I burnt through my battery filming a bunch of helicopter stuff, since this aspect of it was really exciting! I don't know how steep the higher pitch ones are in my video, but I can say they were significantly steeper than the cirque runs at Snowbird (including Great Scott) and Cirques at Whistler/Blackcomb. I would conservatively guess some of it was 45* and up. The runs are also pretty sustained, so it may be 40-50* for 1000' vertical feet, compared to many places where it may be steep for just one small part. The camera is deceiving and makes it look pretty tame.
We could really only ski steep terrain in the higher elevations due to the high avalanche risk. This was due to intense rain earlier this year in Valdez, and a different snowpack this year (google Damalanche). While we were out, there were several destructive and sizable avalanches in nearby mountains, and I believe a guide from another heli company was killed in a slide one of the days we were riding.
The picture above looks more like the Cat skiing we did on the days we couldn't fly. Lots of rollers, trees, rocks, and fun natural features to play on. In Valdez most of the helicopter accessed terrain is above the tree-line. That looks more like BC or somewhere in Canada. Looks like fun!
Sorry for the long first post, but consider it an introduction! For anyone on the fence, I definitely recommend going to AK. The mountains were very unique, and had a totally amazing feel (even compared to the Alps). Just plan that if you go, you will want to go back! This was my first trip, and I'm already trying to find a way to convince my wife and bank account to go back next year! I promise if you go, you won't find it boring!
