....how do you control speed in the steeps? Like, I want to turn, STOP. Turn, STOP. ....controlling my speed, how do I do that without traversing the whole bowl on every turn?
You need to do what people upthread said.
1. Make completed turns
Complete your turns to slow yourself down and stop. Imagine your turns as C-shaped. Spend equal time spent going across the hill at the top of the turn, then going down the hill, and last, going across the hill in the new direction. That last part and the first part are where you slow down. The middle part is really scary on steeps, as you gain speed when the skis are pointing downhill. Work on feeling all three parts of the turn as they happen, and try to equalize them to get a C shape. Round turns are good.
Your body and unconscious mind needs to learn that completing your turns across the slope and even a little
up the slope will slow you down no matter how fast you were going when your skis point downhill. Teach your body and unconscious mind this fact by doing completed turns on beginner terrain, then slowly work your way up to intermediate terrain. Repeat repeat repeat.
What you don't want to get used to doing is hockey stops to slow you down in the middle of a run when you are gaining speed. Gaining speed comes from not completing your turns.
Another way of saying all this is use direction for speed control, not friction.
Another thing you don't want to get used to doing is rushing through/past the top part and middle part of a turn. If you do that, especially in bowls, you'll end up throwing yourself out of balance. Learn to make "patience turns" where you allow all ten toes to point down the hill before pointing them across the hill. You may need the assuring voice of an instructor to take you through this process.
2. Turn release and initiation
If you have trouble starting a turn after completing the last one, with your skis pointing a little bit uphill, you may need to relearn how to start a turn. How do you start a turn now? In other words, what's your initiation process? Do you know how you currently release the old turn? I'm speaking instructor-speak here, but it's a good language to learn because it allows communication about what's going on.
3. Learn to make short radius turns
On real "steeps" you may want to use short radius turns, where you do C-shaped turns but keep them confined to a narrow corridor. You will probably need an instructor to help you learn to do short radius turns, if you want to do them properly. You'll need to learn to use "upper-body-lower-body-separation" to do short radius turns.
4. Get out of the backseat
If you are traversing to stop on bowls, all you need to do to shorten that traverse is point the skis uphill a little. Practice that over and over again in a long traverse. If you can't get the skis to go uphill even a little, if they are running away from you, dragging you across the hill, you are in the back seat. Close your ankles so your lower legs come up from your skis at a forward tilt, lift your hips upward, and project your hands forward enough to keep your elbows in front of your sideseams. This will hover your body over the front part of your skis and allow you to do miracles on your skis that currently you cannot do. If you move your whole body down and up, make sure that down-up movement is at a forward diagonal to the top of your skis, not straight down and up and definitely not down and up-and-back.
5. Learn on learning terrain first
Lessons are always a good idea. Be prepared to learn on low-pitch terrain where the instructor knows you will not be put into survival mode. When going slow on easy terrain, you'll be able to focus on the movements that you're learing. They will be harder to master on low pitch terrain without the help of momentum from speed, so learning there will be beneficial.
Best of luck! Is your season still going strong?
