Here are a some snapshots from of a major Colorado Snowstorm
that hit on December 20th, 2006. At 9:00PM, I plunged a yardstick
into the front yard and measured 22" of fluffy white stuff that
had fallen that single day ... but as can be seen in the picture
from my office window,
drifts were much higher. There was even a little bit more overnight
as Dirk-n-Kyle did an "official" measurement of 25" the
next morning. It actually shut down the Denver airport for 45 hours - my wife got stranded in Las Vegas for a couple of days.
