Summaries
For 2007-2008 Season
04-18,19,20-2008: During this Friday
through Sunday period, thousands of visitors came to Mt. Washington to
enjoy an excellent stretch of spring weather. Over the course of
the weekend, Snow Rangers, members of the Mt. Washington Volunteer Ski
Patrol and AMC caretakers responded to 7 incidents. Three
medical related calls, a broken pelvis and three leg and knee injuries.
One rescue was in technical terrain and required two 300' lowers.
04-09-2008: A skier was at Lunch Rocks
with a group of people when he was struck in the face by falling ice.
The group had intentionally positioned themselves in a location that
offered shelter from icefall, but the piece silently threaded its way
through the rocks and impacted the victim, causing him to fall
approximately 70 feet down the slope. Realizing the severity of
the injury, his friends rapidly treated him and began transporting him
down to Hermit Lake. He was transferred into another toboggan at
Hermit Lake and transported to Pinkham Notch via snowmobile, where he
was loaded into an ambulance and transported to the hospital. Due
to excellent response from his friends, good trail conditions and
machine assistance, the patient was in an ambulance in just over one
hour from the time of his injury.
03-30-2008: During the afternoon of Sunday,
March 30, Forest Service Snow Rangers at Hermit Lake were alerted to an
avalanche incident in North Gully in Huntington Ravine. A climber
elsewhere in the ravine witnessed the slide and was able to connect with
911 via a cell phone. Two Snow Rangers responded with snowmobiles and
were on the scene 18-20 minutes after the incident took place. The
details that follow were gathered from the climbers involved.
Two climbers were emerging from North Gully onto
the more open slopes above the gully. After simul-climbing the gully’s
midsection, they unroped and began to climb the snow up toward Ball
Crag. They identified an area of potentially unstable snow and decided
to move off to the side of the slope and travel one at a time. One of
the climbers triggered an avalanche but neither were caught or carried
in the slide. Unsure of the outcome below, they quickly worked their way
around the ravine and descended the Escape Hatch to see if anyone needed
help.
A second party of two believed the first party had
already finished the climb, and began the first ice pitch. The leader
arrived at a fixed belay above the first pitch of ice and clipped his
rope to the anchor with a carabiner. He was in the process of backing up
the anchor when the avalanche came from above. At this point the anchor
was serving as a piece of protection and he was essentially still on
lead.
The avalanche carried the leader downslope over the
top of the first pitch of ice. The belayer was unanchored at the bottom
and was lifted upslope and into the ice. He was able to maintain control
of the belay and the fixed anchor held, resulting in approximately a 50
foot fall for the leader. Both climbers were shaken up, sore, and had
damaged their helmets in the fall. Examinations by Snow Rangers at the
scene found no serious injuries. The climbers stayed overnight at the
Harvard Cabin, where the following morning they reported general
soreness but no other injuries.
The weather leading up this incident is an example
of a classic setup for an avalanche cycle. On Friday, March 28, Mt.
Washington received 6.4” of 7.8% density snow. Hermit Lake recorded
almost 8” from the same weather system. Friday night and Saturday the
winds wrapped from the W to the NNW and increased in velocity before
falling again on Sunday (from 1mph Friday afternoon to a peak of 99mph
Saturday then back down to single digit speeds Sunday). Evidence of
natural avalanche activity was visible Sunday morning in several
locations, including Hillman’s Highway, South Gully, Raymond’s Cataract,
the Lion Head Summer Trail, the East Snowfields of the summit cone, and
in small snowfields that descend from Lion Head toward the Tuckerman
Ravine Trail. Avalanche danger for North Gully on Sunday was rated
Moderate.
Fortunately this incident turned out well for all
parties involved. It very easily could have been worse. Several lessons
can be gleaned from this incident:
·
Choice of route. Five of eight gullies in Huntington had
Low avalanche danger while three (North, Damnation, and Central) had
Moderate. In regards to snow stability, choosing anther gully would
have been a safer option.
·
Climbing below another party. Ice climbing below others
always carries additional risk, whether it’s from falling ice and rocks
or avalanches. The party that was hit by the avalanche understood that
climbing under another party was a bad choice. They thought that the
gully was clear and that it was safe to start up. It is difficult to
see the entire gully from the base of the ice, but a short walk to a
better vantage point is all that is required for a view of the entire
gully.
·
Ongoing stability assessments: The top party did a good
job of recognizing the unstable snow at the top of the climb. Traveling
one at a time off to the side of the area in question helped prevent
them from being caught in the avalanche. Had they wanted to protect
themselves further, they could have roped up again and climbed to the
top using belays and protection.
03-03-2008: A group of mountaineers were
glissading the Lion Head Winter Route when one of them lost control and
fell down approximately 75-100 feet through the trees to the bottom of
the steep section of trail. Along the way he hit some trees and came to
a stop against a large stump. USFS Snow Rangers were notified of the
incident by a hiker who had been sent to Hermit Lake to get help.
Although below the steepest section of trail, the patient was found in
terrain sufficiently steep to warrant belaying the litter downhill until
the flat section of trail. From here he was sledded to the junction of
the Winter Route and the Huntington Ravine Winter Access Trail, then
transported via snowmobile and haul sled to Pinkham Notch Visitor
Center. The Winter Route is a steep mountaineering route which requires
the ability to self arrest in the event of a fall. Glissading was a
reasonable descent option given the soft snow conditions on this day;
however, one should never glissade at a speed beyond his or her ability
to self arrest.
01-26-2008: A climber was injured from
a sliding fall while descending in Huntington Ravine. A party of
two started up Odell Gully around 3:00 pm on Saturday afternoon.
After completing the main ice climbing section, they traversed to the
east to begin their descent. Neither of them had their headlamps
with them and darkness complicated their descent. According to the
party, they were in the lower section of the Escape Hatch when one of
them lost his footing and began a sliding fall. Unable to self
arrest, he slid approximately 150 feet before slamming into a tree and
stopping. The fall resulted in injuries to his back and legs.
The two were able to get to the Harvard Cabin under their own power
where local guides and the caretaker provided assistance to the climber
and notified the USFS Snow Rangers who arrived at the Harvard Cabin
around 9:30 pm. The patient was reassessed, immobilized on a
backboard and transported to Pinkham Notch via snowcat where he was
transferred to an ambulance and brought to the hospital. We later
learned that the patient fractured two vertebrae in his lower back and
had numerous sprains and contusions
Lessons Learned: This was the third sliding
fall injury in three days that may have been prevented with a quick self
arrest. The surface that all of these occurred on is a very hard
icy snowpack from the January thaw, which is difficult to stop on.
If you don't arrest your fall immediately you will get out of control
fast. In each of these incidents, the parties involved did a good
job getting to the Harvard Cabin under their own power.
01-25-2008: A party of four was
ascending the Fan in Huntington Ravine when one of them fell and slid
into two other people in his party causing them to fall as well.
One of three involved in the fall was unable to self arrest on the icy
surface and tumbled about 50 feet before hitting a rock. He
sustained a soft tissue injury to his left thigh. The patient's
party was able to assist him down to the Harvard Cabin and notified the
caretaker of the incident and requested assistance. A Snow Ranger
assessed his injuries and transported the patient to Pinkham Notch via
snowmobile.
01-24-2008: A party of three was
descending the Tuckerman Ravine Trail on the summit cone of Mt.
Washington when they lost the trail. Due to poor visibility, they
wandered off trail to the east and began descending a steep snowfield.
One of them caught her crampon, causing her to trip and start a sliding
fall. One of the other people in the party chased her down and was
able to assist her in stopping the sliding fall. The person who
tripped had no experience self arresting. During the fall, the
person twisted her ankle and her party was able to get her down to the
Harvard Cabin in about 5 hours where they spent the night. The
next day USFS Snow Rangers assessed, treated and transported the patient
down to Pinkham Notch via snowcat.
01-18-2008: At 9:20 pm on January 18
the USFS Snow Rangers were informed that a solo climber was overdue from
his climb in Huntington Ravine. The overdue climber had signed into the
winter climbers register at Pinkham Notch with the plan of climbing
Central Gully in Huntington Ravine. According to his friends who
reported him overdue, he had experience in many gullies in Huntington
Ravine and had talked about Odell Gully as another option for his day.
A team searched the access routes into Huntington
Ravine between 10:00 pm and midnight on the 18th. Due to snow
stability concerns, search teams didn’t enter avalanche terrain until
first light the next day to begin searching Huntington Ravine.
Shortly after sunrise, the missing climber’s body was found in avalanche
debris below Odell Gully. The climber was on top of the debris and
died as a result of being avalanched out of Odell Gully. He was
put in a technical
litter, lowered 500 ft to the floor of the Ravine and transported to
Pinkham Notch by the USFS snowcat.
The avalanche danger rating for January 18 was
posted High for all forecast areas in Huntington Ravine. The definition
of this rating states natural and human triggered avalanches are likely,
unstable slabs are likely on a variety of aspects and slope angles, and
travel in avalanche terrain is not recommended. This rating was based
on active wind loading of new snow that had been accumulating since
snowfall began around 4 am that morning. Winds associated with the
storm began out of the south before shifting to the west around 12:00 pm
and increasing to the 60-70 mph range with a peak gust on the Summit out
of the west of 86 mph (139 kph) at 5:42 pm. Recorded snow totals from
this storm were 3.9” (10 cm) at Hermit Lake and 3.1” (7.9 cm) on the
summit of Mt. Washington with locally higher amounts. The density of
the snow was lighter at the beginning and became heavier through the day
with an average density at Hermit Lake of 12.8%. Odell is a popular
climbing route with sections of snow and grade 2 and 3 ice. It faces E
and ENE and has multiple avalanche start zones. The winds associated
with this storm were ideal for loading Odell by starting out of the
south and wrapping around to the west. It is believed that the climber
triggered the avalanche, though this is not conclusive. The size of the
avalanche was classified as D2R3. D2 refers to the destructive force of
an avalanche and means that it could bury, injure or kill a person. R3
means that the avalanche was medium sized relative to its normal path.
Evidence of natural avalanche activity from this storm was observed on
similar aspects.
We would like to thank Mountain Rescue Service,
Androscoggin Valley Search and Rescue, the Appalachian Mountain Club,
the Harvard Mountaineering Club and the Mount Washington Observatory for
assisting in this incident.
Lessons learned: It is easy to look at incidents such as this one
and make simple judgments on the victim’s actions. Undoubtedly, most
people would change their plans when a current avalanche forecast
projects avalanches as being likely on their intended route.
Nonetheless, the majority of our avalanche fatalities and serious
accidents have occurred in areas that were posted with High avalanche
danger. This contrasts with the general trend around the world where
the majority of accidents happen under a Considerable rating. Though
this accident did happen in an area that was rated as High, it could
have occurred under a rating of Low, Moderate or Considerable.
As a solo climber you are often exposed to a
greater degree of risk than a roped climber. In this incident the size
of the avalanche probably had little to do with the outcome. Had the
victim triggered an isolated pocket of unstable snow, as is feasible
under a rating of Low, the end result would likely have been similar.
Although a rope cannot save you from all mountain dangers it does
substantially increase the size of your safety net if used properly.
When approaching a suspect area the best use of a rope incorporates
solid protection that is located to the side of the pocket or snowfield
in question. This is by no means a failsafe tactic but it does provide
some extra security should you be knocked off of your feet by snow,
falling ice, etc.
Secondly it is worth noting that the US 5-Scale
Danger Rating System is a continuum and not a series of 5 distinct
categories without overlap. Within any particular rating there is also
a range and we frequently try to discuss this in the daily avalanche
advisory. When the victim passed the Harvard Cabin the avalanche
advisory stated the following: “N-facing aspects will be the first to
move up into the High rating with E and S-facing aspects to follow as
the winds shift.” Armed with this data, it
would be prudent to consider the other options if one was determined to
climb a gully in the ravine that day. By the time the victim was
approaching the start of the climb the winds had begun their forecasted
shift and Odell Gully was in the direct lee of wind loading. Farther to
the right, gullies such as North and Damnation likely had less loading
occurring and would have had smaller sections of suspect snow to
navigate.
Mountain skills are complex and require a high
degree of technical training in a variety of disciplines. This climber
had a lot of experience climbing in Huntington including numerous solo
ascents of gullies. He was well prepared to deal with the weather and
steep mountain terrain found in Huntington Ravine. As is often the case
in avalanche accidents, it appears that his technical climbing
experience surpassed his knowledge of mountain snowpack. In addition,
the victim was not carrying any avalanche safety equipment. Though it
did not make a difference in this scenario, carrying this equipment
provides an additional tool should the unthinkable occur. Even if
climbing alone this gear can help you out when things go bad. Other
climbers in the area could locate you if you were buried while wearing a
beacon and you could provide the same service for them. With this said,
self sufficiency is paramount in avalanche rescue so having a party of
two or more is needed. Having these items with you should be standard
practice anytime you enter avalanche terrain.
12-20-2007: On Thursday morning
December 20th three climbers were suiting up after breakfast
at the Harvard Cabin when USFS Snow Ranger Jeff Lane entered the
building. Jeff was in the process of writing the avalanche advisory for
the gullies of Huntington Ravine and asking visitors what their plans
were for the day. Jeff got into a conversation with two of the three
climbers about avalanche stability issues and the Considerable and
Moderate postings for the Ravine. Their plans were to climb for a
couple of days with Pinnacle and Damnation as the desired routes, the
former being the main goal. With Pinnacle being posted at Considerable
Jeff called Chris Joosen on the radio about his thoughts and concerns
about a party ascending Pinnacle. Jeff and Chris agreed that that they
could not recommend Pinnacle posted at Considerable or Damnation Gully
posted at Moderate, but would instead focus on presenting the stability
facts. Jeff discussed what gullies had more instabilities than others
and convinced them Pinnacle was not a good idea. Although Damnation
held the possibility of unstable slabs, they were less likely and
widespread than areas posted at Considerable. After a 15 minute
conversation they said they would climb Damnation today and perhaps hit
Pinnacle tomorrow (Friday). The weather conditions as they entered the
Ravine included snow, light winds and limited visibility. They decided
to head up to Pinnacle to look at it and then traverse over to Damnation
rather than head straight up to it. After looking at Pinnacle from
below they traversed under Central Gully and began heading across the
top of the Fan. They changed their plans partway across and headed back
following their original plan to climb Pinnacle Gully. On the approach
to Pinnacle they began pushing through deep snow that they said was up
to the chests. They felt that because it was loose and unconsolidated
that it was safe and not in risk of avalanching because in their opinion
a slab did not exist. When the three were about 25 meters from the
bottom of the ice which marks the traditional 1st pitch, the
slope fractured and failed above them just below the ice. At the time
of slope failure the 1st climber was a few feet above the 2nd
and about 10+ feet above the 3rd. KA was out front and
yelled “Avalanche!” and grabbed GW below him. All three were flushed
down the slope, but remained on the surface cart-wheeling with the
entrained snow. KA and GW were still next to one another about 75m
below their high point while KB was sent almost twice that distance
farther down slope. They were extremely fortunate to have no injuries
and to remain on top of the snow. After shaking themselves off they
proceeded to search for missing gear and decide what to do next. Two
wanted to climb the gully now that it had, in their opinion, been
rendered safe by the release of its instabilities. The third was done
for the day. They decided that they would all descend.
Lessons Learned: Often it is only in 20/20
hindsight that the reasons for an incident present themselves, but
occasionally the natural world provides clues that were so obvious they
should have been seen and heeded. Each year we have examples of common
mistakes that have human factors and psychology behind them even though
the natural bulls-eye information was there. This is such an incident.
Environmental Factors:
- At 7am the summit temperature was around 15 F
with a south wind at 20mph. Approximately 3.5 inches of new snow was
recorded at the summit while Hermit Lake in Tuckerman and the Harvard
Cabin in Huntington each reported about 4 inches for the same period.
Snow continued through the morning bringing another 2-3 inches to all
areas by noon.
- Pinnacle is a steep E/ENE facing gully that is
cross-loaded by S winds. In addition to spindrift and sluffing from
up high, the entire first pitch is water-ice which does not hold
snow. All of this snow piles up at the base of the gully on a slope
of increasing angle averaging between 30-35 degrees. This build up of
snow accounts for the group’s comments of chest deep snow even though
only 4-5” had fallen. The light 7.7% density snow and light winds
explains their impression that slabs did not exist. Light density
snow slabs can be practically indiscernible and although it appears
unconsolidated and loose, even the slightest cohesion can create a
slab. Slab density closer to the ice was likely increased by the
packing of spindrifts and sluffs from higher in the gully.
- Pictures taken right after the slide by the
group showed constant sluffing from the rock face that forms the
gully’s left wall, further contributing to the accumulations on the
slope.
Human Factors:
- Jeff Lane spent 15 minutes
of detailed conversation with the party about snow stability in
Huntington and specifically the issues in Pinnacle. The discussion
ended with Jeff not being able to recommend their desired climb based
on instability and the associated Considerable rating. When traveling
to various mountain ranges that have an avalanche advisory and you’re
able to personally speak with the individuals that developed the
forecast it should be acknowledged as key data. In addition to
avalanche forecasters there are ski patrollers, guides, Wardens, and
Rangers working in their local mountains that can give you valuable
safety advice worth listening to. While you should not make your
decisions based 100% on the advice of others, when available, use
personal focused advice from experienced local avalanche expertise as
a critical tool to help your decision making process.
- The group initially passed Pinnacle and then
convinced themselves that it was okay. It becomes easy to overlook
all the red flags when desire overcomes reason. We must enjoy our
winter pursuits on the mountain’s terms, not on our tight time
schedule. It’s easy to make a go/no-go
decision on the days that are truly nasty or sunny and stable. It’s
the large spectrum in between these
two when you must err on the side of caution and fight the desire to
“squeak through” and “beat” the mountain. Snow stability is hardest
to accurately assess when the margin of error can put you into either
a green light or red light situation based on how you’re seeing the
data. The bulls-eye data can be a little more difficult to pick out.
For these reasons most fatalities occur under a Considerable avalanche
rating.
-
Safe
travel rules were not adhered to and rescue equipment was not worn.
Safe travel rules include (1) Travel one at a time, (2) Don’t travel
over or under your partner, and (3) Have a plan in mind about exactly
where you’ll go if an avalanche happens. Number 3 can be very
difficult to manage in every situation, but rules 1 and 2 mitigate
risk well and limit the number of individuals in a potentially
hazardous situation to one. This is absolutely critical to individual
and group survival if an avalanche does occur. Having only one person
buried allows more individuals to focus on the rescue, thus increasing
the odds of survival. On the other hand, having the whole group
buried brings the group’s chance of survival pretty much down to
zero. This group was very lucky as all of them were caught, entrained
in the debris, and brought downhill. Had someone been buried, the big
problem would have been the lack of beacons, probes, and shovels. If
anyone was completely buried this incident would have likely turned
out tragically.
