Avalanche Advisory for Tuckerman and Huntington Ravines
Posted: 8:31 a.m., Wednesday, January 14, 2004

Tuckerman Ravine currently has LOW, MODERATE, and CONSIDERABLE avalanche danger. The Little Headwall and Lower Snowfields have Low avalanche danger. Natural avalanches are very unlikely and human triggered avalanches are unlikey except in isolated pockets. Normal caution is advised. Left Gully and Hillmans Highway have Moderate avalanche danger. Natural avalanches are unlikely and human triggered avalanches are possible. Use caution in steeper terrain. All other areas have Considerable avalanche danger. Natural avalanches are possible and human triggered avalanches are probable. Be increasingly cautious in steep terrain.

Huntington Ravine currently has MODERATE avalanche danger. Natural avalanches are unlikely and human triggered avalanches are possible. Use caution in steeper terrain.

Full arctic conditions have once again taken hold of the mountain. The summit is currently reporting temps of -41C (-41F) with little reprieve in the near future. Winds shifted from W to NW overnight and have increased to a constant 115 kph (70 mph) with higher gusts. This has blown much of the past days' light density snow to lee areas where wind slab is currently building. Some areas especially in Huntington may be scoured down to old surface with wind deposition and instabilities occurring lower down in the approaches to gullies. With temps as low as they are settlement rates are undoubtedly poor and we can expect instabilities to linger for the next few days. The windchill at the summit is approaching -100F and new daily low temperature records are being set. The wise may want to think about staying indoors and being an armchair mountaineer for the remainder of the week.

The John Sherburne ski trail has variable conditions. Expect areas of water ice, some blowouts, abrupt water bars and open holes. Be prepared for sudden changes in the trail.

THE LION HEAD WINTER ROUTE IS OPEN. This is a steep and challenging route. Ice axe, crampons, and the skill to use them well are necessary for safe travel. Remember, it is always easier to go up than come down.

AS ALWAYS, THIS ADVISORY IS ONE MORE TOOL TO HELP YOU MAKE YOUR OWN DECISIONS IN AVALANCHE TERRAIN. It should be used along with your own snow stability assessments, knowledge of safe travel techniques, skill in reading mountain weather's effect on the snowpack, and avalanche rescue.

Please Remember:
