As we enter the spring season and East coast skiers and snowboarders begin their annual sojourn to fabled unforgiving steeps of Tuckerman Ravine in the White Mountains of New Hampshire, we were reminded a snowboarder who fell into a deep hole that had formed on the eastward facing glacial cirque and left thousands of onlookers with their hearts in the throats as he disappeared into its icy depths.
Thankfully the snowboarder was carrying an ice axe at the time and was able to self rescue. He emerged minutes later slightly hypothermic but otherwise relatively unscathed.
If you are planning on skiing Tucks this spring please remember you alone control your own level of risk by choosing when, where, and how you approach this unforgiving terrain. Be prepared, be safe, have fun.
Here is a longer clip from a different angle of the same incident. In it the crowd waits for a few tense minutes unsure of the fate of the snowboarder and erupts in cheers once he emerges and is able to ride down unassisted. He was met at the base by ski patrol at the bottom and treated for hypothermia. Read a full breakdown of the event from The Mount Washington Avalanche Center below.
Mount Washington Avalanche Center Report:
On Saturday, April 15, 2023, a snowboarder attempting to descend the Tuckerman Ravine Headwall, lost control resulting in a fall into one of the deep, open waterfall holes that forms each year from water runoff and melting. The person ultimately was uninjured and able to extract themselves from the hole after about 10 minutes. This incident and near-miss highlights a dangerous and high-consequence springtime hazard that has injured and killed visitors in past years.
SUMMARY:
Saturday, April 15, 2023 was a classically busy spring day in Tuckerman Ravine full of skiers, snowboarders, and hikers. An estimated 3000 people visited Tuckerman Ravine throughout the course of the day. For the most part, skiers and riders were enjoying warm temperatures, soft snow conditions, and plenty of sunshine.
Throughout the day, a handful of aggressive skiers were descending over the Tuckerman Ravine Center Headwall, which at the time was one of the most technical and hazardous features in the ravine. The people descending in this area were encountering mandatory drops over cliffs, ice flows, and open waterfall holes in the snowpack. Knowingly or not, descending this area means accepting very high levels of risk.
In this instance, a snowboarder began descending one of these “lines” before losing control in the incredibly technical terrain, falling past a couple ledges, and ultimately into one of the main open waterfall holes in the snowpack. You can see the full video of this incident here.
Luckily, the snowboarder landed on a rock ledge about 15 feet into this large hole and was able to stop himself from falling further down into the hole, which extended well out of view to an unknown depth. Uninjured, he was able to remove the snowboard and use an ice ax to climb up out of the hole.
TAKEAWAYS:
At a distance, the takeaways from this incident seem relatively obvious – traveling above large open holes in the snowpack in highly technical terrain has extremely high consequences and little margin for error. However, there are several nuances to this hazard and this location that are worth pointing out for the goal of education and preventing these accidents in the future.
SPATIAL REFERENCE AND PERSPECTIVE:
In steep backcountry terrain, especially if it is unfamiliar, awareness of where you are in relation to certain terrain features can be very challenging. Referencing a terrain feature on the way up and scouting a route can be helpful, but when the perspective completely flips looking down the fall line, and it’s easy to lose spatial reference. This phenomenon is compounded by steep convexities, where “blind” entrances are common. The Tuckerman Headwall is a great example of terrain where spatial reference is challenging without an intimate knowledge of the terrain.
RISK AND MARGIN FOR ERROR:
Remember: You control your own level of risk by choosing when, where, and how you travel in the mountains. Think critically about route choices and the potential consequences of each option. Fully understanding the consequences of a hazard and the ability to maintain control over your exposure to that hazard will help maintain your acceptable margin error when taking on risk in the mountains.
WATERFALLS AND GLIDE CRACKS:
As warm temperatures, rain, and water runoff continuously melt snow during spring, it is common for large, deep holes and cracks to form in the snowpack. There are a few mechanisms of formation including concentrated water runoff falling onto the snowpack, snow becoming undermined from water runoff below the snow surface, and from snowpack movement (also called creep) and separation. Sometimes, these cracks and holes are reminiscent of a crevasse, which are formations specific to glaciers. These openings in the snowpack can be very deep (over 50 feet) and large enough for a person to fall into. In most cases, these openings have no reasonable exit until the snow completely finishes melting. Here are a couple key points about this hazard: Glide cracks can be seen as horizontal lines in the snow pack from a distance. It is best to distance yourself from these features because the surrounding snow can be weak, undermined and connected to the same crack. Deep holes often appear as depressions in the snowpack from a distance. They are often found next to or below rock buttresses and boulders where water collects and melts snow from the surface. In the route planning process, it is important to identify where these could be found and to make sure there is a way to avoid them. Traveling above these features increases the consequences of a fall. Fresh unsupportive snow can mask the openings.
