Avalanche Advisory for Tuckerman and Huntington Ravines
Posted: 8:07 a.m., Wednesday, February 18, 2004

Tuckerman Ravine has MODERATE and LOW avalanche danger. The Lip, Bowl and Headwall have Moderate avalanche danger. Natural avalanches are unlikely and human triggered avalanches are possible. Unstable slabs are possible in steep terrain. Use caution in steeper terrain. All other areas have LOW avalanche danger. Natural avalanches are very unlikely and human triggered avalanches are unlikely EXCEPT in isolated pockets. Normal caution is advised.

Huntington Ravine has LOW avalanche danger. Natural avalanches are very unlikely and human triggered avalanches are unlikely EXCEPT in isolated pockets. Normal caution is advised.

Today looks to be a splendid day on the mountain with reasonably mild temps and light winds. While the temperatures are forecasted to climb a bit over the coming days, winds are expected to pick up tonight and be fairly gusty through tomorrow. Today's conditions are exactly what we need to help consolidate the snowpack as opposed to the arctic temps experienced over the past few days. Despite having no new snow, the winds have continued to bring snow into Tuckerman's especially from climber's right side of the Headwall through the Lip and over to the Sluice. Neither the fracture line on the Lip or the boot line up the Sluice from yesterday are visible today. In these areas we can assume that softer slab has been laid down over the dense windslab found in many areas of the ravine. Don't let the bluebird skies and the lack of recent snowfall lure you into complacency. Some of the areas that are at Low today in Tuckerman have just come down from Moderate and are at the upper end of their present rating. Even areas posted at Low today may have lingering pockets of instability. Know how to recognize and avoid these potential hazards.

The John Sherburne ski trail has some soft areas but expect hard pack snow to prevail particularly on the lower half. Anticipate water ice, rocks, and thin cover in many locations. Though the surface looks good be prepared for these hidden hazards and 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.
