Got a taste of it last season, inbound in Kirkwood after a huge 3 day dump. After an ample and fast turn to the left I did another to get back on the right, and ended up on a small steep hill, that was closed off from the rest of the trail, I ended up there by mistake and found my self on this unstable and loaded steep mini avalanche waiting to happen. I didn't want to keep traversing, so I tracked back stepped off the board and started to climb up the slope, only to find myself buried in neck deep snow at each step. Using the board as a tool I was trying to climb up, instead I was digging a wall of snow in front of me. That made me realize how much snow I was dealing with and what would have happened if it moved on me. I was at that point maybe 5 feet away and under the boundary. Chair lift in sight.
Getting back up was exhausting and a wake up call. Same day, later, cutting trough a tree section where the wind blown snow was 3 - 6 feet higher than anywhere else, I found myself stuck chest deep just riding over it. It wasn't a tree well but just very very light and uncompressed powder that gave way immediately. Even if you don't get buried getting out makes you realize what you're dealing with. That was again INBOUND, in a resort after a massive 3 day 10 feet dump. Be careful out there.
