While it's nice to say you've done it, and there's a feeling of accomplishment, there is a TON of good skiing without coming down from the Peak, and skiing that will challenge all but the most expert of skiers. Plus, in the time you'd wait in line to go up the Tram on a nice day you could lap Challenger 3-4 times and PowderSeeker twice that.
Good advice.Here's my extended advice on testing your skills for Liberty.
Ride up Powder Seeker. Go left off the chair as far as you can, way past the bowl, at least 75% of the way around. Ski down. If you're comfortable with that and could have handled 2-3 times more of the same without a flat place to stop your'e ready for Liberty. Remember snow conditions on the far left of the bowl area are almost always better than the snow on the peak because it's so protected and gets refilled from above.
Other ways to test your skill are the Challenger Chair or the Headwaters Chair. The only problem with those two is there is a limited view of the terrain before you're committed and no way to ride down.
The visibility component in the high alpine may be a new challenge and hard to overstate. Light can be bright but flat. Clouds can appear out of nowhere so you start up powder seeker in bright sun. You stand in the tram line as a few clouds blow in and when you get to the top it's snow'n and blow'n. Also snow conditions can be significantly better or worse than front side conditions.
While you're back there follow the signs to the base area which take you to "Screaming Left" and the yurt under the Shedhorn quad for a burger or a beer. Best views of the backcountry available.Then after your legs are recharged, ski down to Shedhorn chair. If you're feeling good take a lap on Shedhorn under the chair or left of the chair. If tired just take the road around the to the top of the Swift Current Chair. You can also get to Shedhorn from the top of Swift Current via Cow Flats and get a taste of the backside without the wind or tram ride. Lots of locals ski the back from the middle down just to avoid the tram line.
One last thought. If you do get in trouble anywhere on the mountain call Ski Patrol on your cell phone. I've done it on Green, Blue and Black runs for guests in trouble. The ski patrol is glad to give you a courtesy ride down, not necessarily because they're nice folks, which they are, it's just easier for everyone to get you down in a sled while you're healthy instead of needing to stabilize a broken leg on the side of a mountain and then carefully transport you to the clinic
All that said, Do go up after 2:30 on a sunny day for sight seeing. Take your poles with you. It's usually windblown so you will be able to get around easier with your poles for support. You will enjoy looking down on the Yellowstone club, Wyoming, Idaho and the Headwaters of the Missouri river.
