Clothes

Got it?NameNotes
  Winter boots If we are planning to use crampons, normal hiking boots are not strong enough.
  Gaiters Unless you want wet toes, these are essential.
  Socks  
  Sock Linkers  
  Shell Parka  
  Shell Pants  
  Long Underwear For day hiking under the shell pants. Anything else is too warm.
  Jacket Fleece is good. Cotton is bad.
  T-Shirt  
  Gloves Again there are many ways to keep your hands warm. Thick warm waterproof gloves with think gloves underneath is how I do it.
  Hat Balaclava's are great too
  Underwear  
  Pants Fleece pants are awesome. Long underwear is also nice.

Equipment

Got it?NameNotes
  Snowshoes The MSR snowshoes are the ones to go for. Ironically, when steve bought his ($129 including a pair of 8 inch tails, good for deeper powder) they were about half the price of the competitors. And, in his opinion, far better. (I can attest to the suckiness of the competition, and I've had my share of equipment failures while renting the competition-- that ignores the performance characteristics!)
  Trekking Poles Not a necessity but they do make the trip a lot easier. Poles allowyou to use your arms to help move you along. You can rent some for very cheap or use ski poles with bigger snow baskets in a pinch
  Sleeping Bag I got away with a 15 degree bag last time. Steverod recommends zero degree only. If you get cold, I recommend zero degree also. Normal backpacking pack should be fine.
  Sleeping Pad Keeping off the tent floor is a great way to avoid the bumps and the cold.
  Back Pack Normal backpacking pack should be fine.
  Maps  
  Compass  
  Flashlight Headlamps rock. They leave your hands free and make life much easier.
  Knife  
  Sunglasses  
  Sunscreen  
  Matches In waterproof container
  Candles Or something to start a stove
  First Aid Kit  
  Death Bag This involves several plastic bags, a brown paper shopping bag. Kitty litter and toilet paper. Remember you pack everything out
  Water bottles Nalgene bottles are the trusty ole faithful. I like the platypus water packs. The benefit is that they let you easily drink water all day. The downside is that they freezer at night. Everyone has their own preference for water containment.
  Signalling device Whistle or mirror
  Avalanche Cord  
  Tarp  
  Flatware  
  Snow Shovel At least one for every two people. The more the better.
