With limited visibility in both ravines we have observed a couple of large avalanches. It looks like the top left of Hillmans Highway released depositing some much needed snow on the lower slopes. A large fracture line was visible across the top of the Left Gully and under the rocks to the left of the Lip.
Tuckerman has picked up 4.5 inches (11 cm) of new snow with strong winds from the WNW that are moving a lot of snow onto the lee slopes. With the strong winds moving this snow the lower slopes can be just as dangerous as the upper gullys.
Summit winds are in the 68 MPH (110 KPH) range with a temperature of - 27 F (-33 C) so travel above treeline can be a real challenge and climbers need to be equipped for arctic conditions.
As discussed in many of our previous advisories, ice dams have been an on going issue in the Ravines, particularly in Huntington Ravine. They are still an issue. As of last Friday Pinnacle Gully had water pouring down the first pitch. Near the top of the third pitch one unfortunate climber punched through a snowy ledge and found himself up to his knees in water. Not an ideal situation to be in when the outside temperatures are below zero and you are a long way from your car. Be very aware of the condition of the ice you are climbing.
THE WINTER LION HEAD ROUTE IS OPEN. The route leaves from the Huntington Fire Road and has orange signs starting on the Tuckerman Ravine trail at roughly the 1.8 mile mark. It is a steep and challenging route. Crampons, an ice axe, and the ability to use them with skill are required for safe travel. Avalanche skills are always required to travel safely in the mountains. Be prepared to do your own stability assessments.
The John Sherburne ski trail is improving with this weeks new snow. However, due to high winds expect variable conditions in the form of whales, drifts, and scouring. Some rocks and waterbars are still hidden under the new snow.
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 mountain weather's effect on the snowpack, and avalanche rescue.
