50 feet of snow?

I have personally survived Skiing on 40 feet of snow on Mt. Shasta one year so I know that this kind of thing is actually possible. For example, skiing on 40 feet of snow is or can be quite hazardous, simply because you are dealing with many unknown variables because you haven't had to deal with 40 foot variables in regard to snow when skiing or snowboarding. 

For example, when I and my friend skied the problem became Tree Wells where snow doesn't gather around trees out about 3 feet from the base of the bigger pine and fir trees at elevation. So, we were at about 7000 feet on Mt. Shasta and skiing down to 7 mile curve on Everitt Memorial highway which is both paved and usually plowed (at least as far as Bunny Flat) during the winters when a lot of snow is there. At first we thought climbing to the top of 40 feet of snow to ski would be the biggest problem we faced that day but this didn't turn out to be true.

Instead it came from tree wells also 40 feet deep around the biggest of the trees that you can see the tips of when snow is 40 feet deep. By the way I was used to skiing on 20 feet of snow because that was actually relatively more normal for skiing around Bunny Flat during the winter in the 1970s and 1980s then.

So, when a friend who is smaller and lighter than me because I'm 6 foot 5 inches tall went over a cornice next to a tall tree. However, it turned out the cornice next to the tree was only a foot or so deep so it gave way like a trap as I tried to ski his same route and I found myself standing on a tree limb with skis on with the top of the snow several feet above my head. I screamed out for my friend and he came back and rescued me. So, first I handed out my skis and ski poles and then he offered his hand after I climbed to the tippy top of the tree knowing if I fell I could fall 40 feet down alongside the tree further into the tree well. But, luckily he was strong enough and I was high enough on the tree to safely exit the tree well without falling down 40 feet. 

However, I steered 6 to 10 feet away from any tip of any huge adult tree that usually looked from 40 feet of snow like a 4 to 8 feet tall Christmas tree because of the 40 feet deep of snow.
