I've been working and living in Lake Louise for 3 years and I'm an avid back country skier with training and a decent amount of experience. Delirium Dive really isn't all it's knocked up to be. It's no different to a lot of inbound terrain at lake and kicking horse. Only difference is it gets less tracked due to the whole needing a transceiver thing. But even then noobs rent transceivers all the time and rip pizzas down delirium. Basically it's not recommended to go without experience but if your going to do it delirium dive is the safest and most easily accessible place to go out of bounds, not because of the terrain type but mostly due to the traffic that goes through there and if conditions are too dangerous patrol won't open it, so they take all of the guess work out of it. If your going without experience don't pick the gnarliest line stay high where possible and avoid sending cliffs and terrain traps. Also talk to patrol to see what's been going on in the area and what route down they recommend. Also go on a clear day so you can see where your going. Ride down one at a time in sections making sure you are in view of each other at all times and stop in areas that are out of the way of any potential avy paths. and don't drop above other skiers/boarders in case you do release an avalanche. Like I said if your gonna do it do it there. I've seen people get caught in more small avalanches on seemingly friendly boot packs at lake louise and kicking horse then I've seen on delirium dive. So onto my next note, when riding in the Rockies there are lots of inbound boot packs too, pretty fun areas with posted avi caution signs, I'm not saying don't do them. It's a good time but if your riding those areas after a storm take the same amount of precaution you would in delirium. I've had a noob snake a chute on upper north cornice that always slides the first few tracks down and buddy didn't know how to handle the sluff and got buried up to his neck and i had to go pull him out. So it can happen anywhere, your not likely to be buried as usually it's just little sluffalanches, but it can happen.
