I think I know exactly what the poster is describing. Maybe I can explain and tell me if I am correct.
The first few hours of the day, a lot of intermediate runs have a couple of steep sections. At these points, less experienced skiers start to really take slow sharp turns and that layer of powder, if it wasn't groomed/packed, starts to turn into ruts and very bumpy uneven looking snow when you are going slow and stare at it.
So the more people that hit these steeps sections slow way down, they make sharp hard turns rutting up the snow making it "bumping appearing". And indeed it is, but it usually isn't that hard packed and some force will flatten it out, which is what many people say about speed and weight.
What you do is the same thing they do, you look right over the front of your skis staring at all of the bumps and the steep sections and the fear sets in and you want to go back to the lodge and grab some hot cocoa if you ever make it back alive. So you work your way down doing sharp turns on your edges in the same ruts making them worse.
Of course, during this time, people are flying by you at warp speed and you wonder why they make it look so easy. But you need to really watch as somebody who goes fast as they hit some of these piles/ruts what their skis actually do. They plow right through the stuff and are not even thrown off balance or up in the air, because it isn't a terrain bump, it is just piled snow.
I've been there.
I ski with friends who are excellent, and of course, while you are working your way slowly through the muck/bumpy looking fluff, they are already back at the lift line wondering if you are stuck in the trees.
I then asked them, how the heck do you guys go so fast through there and not get affected by the rutted up snow and bumpy looking stuff.
1) Go fast! Much faster. This is entirely fear based. They just said, hey, forget the fear and go fast, try it.
2) Look downhill at your line and ignore the scary looking rutted slop of snow..obviously you are going to see it, but don't stare right over your skis waiting for a wreck to happen.
3) Be ready for some bumps and keep your legs flexed and ready to maintain balance.
4) Did we tell you to go faster and just fly/plow right through that stuff!?!?!?!
So I started to just say, ok, screw it, I AM GOING FOR IT, LIVE OR DIE!!!
Anyway, what I found out:
1) Speed is indeed your friend. Since we are guys and 5'10" in height average upwards of 200lbs...our speed and body weight made nothing of those scary looking rutted snow sections. You will literally plow through them and they hardly affect you at all often.
2) The ride got much smoother and easier on my body and legs. I was much less fatigued. Doing all of those sharp turns in that crap is very hard work and time consuming. Going faster is actually much easier on the body/legs and your stamina with descent form/technique.
3) Watch out for the big bumps that are really bumps, those will throw you for a loop, ignore the small stuff, watch out for those big ones that can really get your airborn so you can try to avoid those or be ready for a small jump and get airbon.
4) Carve larger sweeping turns while doing this. Don't dig in the edges like on hard groomed runs that is required.
Much better now, and I am not exhausted after a simple intermediate run that gets rutted up..and I can now keep up with my friends and have more confidence/fun.
