GNFAC Avalanche Advisory for Wed Dec 9, 2009
The Bridger, northern Gallatin, northern Madison Ranges and mountains around Cooke City:
The Bridger Range and northern Gallatins have three feet of supportable snow on the ground. Skiers in the northern Bridgers are finding scoured slopes on north faces and wind-loaded drifts on the south. Strong winds yesterday and today have likely blown all the remaining loose snow onto leeward slopes where it's still possible to trigger a slide.

GNFAC Avalanche Forecast for Mon Dec 7, 2009
The Bridger, northern Gallatin, northern Madison Ranges and Mountains around Cooke City:
The Bridger Range and northern Gallatins have the deepest snowpack in the area with a settled base depth of close to three feet. This pack remains relatively strong despite the new snow, cold temperatures and strong winds we've experienced during the past few days. Strong E-NE winds have scoured north and east facing slopes while depositing firm wind slab on south and west facing slopes.
60 cm of weak, unconsolidated facets. This snowpack does not have a leg to stand on. We sunk straight to the ground when we stepped out of our skis. Watch out when we get more snow.

With numb fingers, Mark Staples puts up the weather station at LuLu Pass outside Cooke City. It was a frigid 2F with a 20 mph wind. It measures wind speed, direction, temperature and relative humidity. This new station was recently purchased by the Friends of the Avalanche Center.
