1. How Does Crystal Mountain Adapt To A Changing Climate Or Why Christmas Should Be on January 25

4. Snowmaking Particulars High pressure water-- 400 psi+ at the base of the hill, not less than 100 psi at the gun High pressure water-- 400 psi+ at the base of the hill, not less than 100 psi at the gun Mix compressed air and finely atomized water at the gun to form ice nuclei Mix compressed air and finely atomized water at the gun to form ice nuclei Combine w/ larger amounts of water Combine w/ larger amounts of water Use 30,000 cfm fans to blow up into the air Use 30,000 cfm fans to blow up into the air If temperature is 28 degrees F or less and humdity is less than 85% then snow is made If temperature is 28 degrees F or less and humdity is less than 85% then snow is made As temperature and humidity go down there is an exponential increase in the amount of snow that can be made As temperature and humidity go down there is an exponential increase in the amount of snow that can be made

5. Snowmaking Particulars Crystal has 87 snowguns capable of converting 4,000gpm of water to snow when temperatures fall to 20 degrees and below Crystal has 87 snowguns capable of converting 4,000gpm of water to snow when temperatures fall to 20 degrees and below The snowmaking system can make one acre foot of snow in 2 hours at 27 degrees or in 34 minutes at 20 degrees The snowmaking system can make one acre foot of snow in 2 hours at 27 degrees or in 34 minutes at 20 degrees Theoretically the snowmaking system can cover the whole ski area with one foot of snow in 4 days if the weather cooperates Theoretically the snowmaking system can cover the whole ski area with one foot of snow in 4 days if the weather cooperates Manmade snow is dense and heavy. About 30lbs/cubic ft. vs 2-3lbs for natural snow Manmade snow is dense and heavy. About 30lbs/cubic ft. vs 2-3lbs for natural snow Manmade snow compacts to 70% by volume vs natural snow which compacts to 10% Manmade snow compacts to 70% by volume vs natural snow which compacts to 10%
