what is "the base"

post #1 of 9
Thread Starter 
do the snowcats pack down the natural (or manmade)snow after it falls and this considered the base? if this is true, how much would 10 inches of accumulated snow pack down to approximately? how deep does the base on a trail have to be to be considered skiable? thanks for the answers!!

10" of fresh Utah snow might pack down to 1"
10" of fresh PNW snow might equal 9" packed

I've had a few first tracks down a just opened run. What looks like three feet of fresh can quickly become a rock gouging ptex from MY base.

My math in those situations says:

3 feet of fresh CO powder = negative base

"The base" - how much snow snowboarders can scrape before you start skiing on rocks and grass.

Depth of Base - An average depth that would be exceeded by 50% of the reported slope area measures.
New Snow - Natural or man-made snow added to the slopes within the past 24 hours.
New is the newly added part of the "base total" I believe..

How much to open depends on the resort. Out west, I notice that a 24 inch base is
usually needed for opening day. As the season goes along, the snow settles and consolidates, so an
early season base of a foot of fluff is unskiable (unless you really hate your skis and knees), but a springtime
base of a foot of hardpack can keep the lifts running.

How much it packs down or settles depends on the original water content. Wetter snow packs down less.

Good runs on as much base with as much new as you can find.

As far as how much is needed, here in the East we are reporting a base of 0-8" and skiing on 5 trails. What you will ski on depends on your love for your skis.

Last year-Killington during Memorial Weekend. I walked between snow sections, while I saw someone else aim for the flowing water, and/or the really wet grass... and he just skied all the way down!

Even though I had my "rock" skiis, I never want to do that much reconstructive surgery on the skiis and my body!

(From a snowmakers point of view)...... Yes, base is once the powder is packed down. Man made snow is already in packed form, so once it is pushed around the mountain, it can be considered base. Its hard to say what 10 inches of powder can be packed to, because as you are grooming, some of the powder squeezes out the sides of the tiller, making a horrible mess to clean up! If you ask any groomer "what conditions do they hate grooming the most?" Most will say powder.
10inches of powder/1 to 2 inches of base
