recent discussions in new Zealand on the
future of alpinism noted that motivation
to push new developments has been fueled
by the knowledge that plenty of unexplored grade
6 lines remain. The situation is similar for those
keen on downhill adventures. even one big line
safely ridden could translate into the most commit-
ted, exposed and ultimately rewarding descent of a
lifetime. as for venues, there’s no place with more
of these than alaska’s chugach mountain range. it’s
little wonder then that alaska has been host to many
defining moments for the world’s best big moun-
tain skiers and riders. For at least two decades the
chugach has been the place to test limits and explore
new lines. chugach occupies such a unique place in
global ski mountaineering because of two oft-said
words: steep and deep.
The chugach is one place where finding these
together is no problem at all.
The Geography of The Chugach
The chugach mountains produce steep snow situa-
tions, second to none. The chugach mountains are a
500-kilometre chain of coastal mountains bordering
the gulf of alaska and stretching from anchorage and
the Kenai mountains east towards canada. Towards
the east the range merges with the more massive
Wrangell mountains and the st elias range to become
the coastal mountains of british columbia. only a
few roads exist through these mountains, making
for an almost unbroken wilderness of peaks. For the
most part air or sea access provide the only reasonable
options for potential visitors.
because of the grandeur of the nearby ranges, the
chugach mountains do not look overly impressive for
their size. That said, the higher peaks are fairly seri-
ous propositions for mountaineers. given their close
proximity to anchorage it is hard to imagine why
none of the 10,000-foot peaks (3050-ish metres) had
been climbed until the summer of 1939. but read on!
it was in 1939 that mt marcus baker received its
first ascent, and bradford Washburn’s account of
the expedition provides a good insight into the reali-
ties of the area1. Washburn had been studying the
problems around accessibility for at least two years,
using a series of aerial flights and photographs. once
Washburn had identified the best approach route,
the next deterrent to his planned exploration was
the ‘unbelievably terrible weather which sweeps the
slopes of these mountains every day of the entire
year’. With this sort of recommendation it is easy
to see that accomplishing anything in the chugach
should be regarded as a success!
The largest peaks are concentrated around the
heavily convoluted coastline of Prince William
sound, which straddles the 60th parallel. This geo-
graphical barrier effectively isolates the sound from
adjacent areas. Whereas the alaskan interior has a
continental climate that is typified by drier weather
and extreme temperature ranges, the chugach has
a maritime climate featuring copious precipitation.
at sea level this may form as rain most of the year,
yet the moist air soon cools as it rises over the steep
mountains, dropping prodigious amounts of snow
in the process.
good positioning and timing can be extremely
useful in the chugach. inclement weather is the
norm and to travel extensively here requires inti-
mate knowledge of the patterns amongst many
subtle microclimates. The big glaciers in particular
lose much less water to evaporation than rocky and
vegetated areas and also reflect incoming sunlight.
consequently clouds may be fewer or less dense in
glaciated areas. However, pockets of cooler air over
the ice form local high pressure systems, and the
resultant glacier breezes are well known to sailors
and ski mountaineers. These glacier breezes produce
cold, foggy and generally inhospitable conditions,
and play havoc with a ski mountaineer’s confidence
that conditions will be better elsewhere. The location
of the ‘elsewhere’ in this story is the famous chugach
beast known as the ‘sucker hole’. such small gaps in
the cloud can often be seen in places but they have a
nasty habit of vanishing just when you need one!
With a snowfall of 600-plus inches per year—over
15 metres—the chugach is a veritable snow factory
and that’s perfect for one other thing: glaciers. The
glaciology is a big part of the chugach environment. 21glacial movement here is very dynamic, in part
responding to the magnitude of accumulation and
ablation processes. To remain stable these glaciers
must move much more snow from their accumulation
areas to the ablation zones than colder interior glaciers.
The result is exceedingly steep and active glaciers, not
dissimilar to those in parts of new Zealand.
chugach glaciers also produce lots of ice. in drier
climates the process of turning firn into glacier ice
takes hundreds of years, but the chugach glaciers
convert snow into ice in only a few years. High
levels of rain and meltwater, which speed up the
densification process, plus the healthy pressures of
continually replenished new snow are some of the
reasons behind this astounding difference. The firn
line extends much lower on the coastal side of the
chugach range because the winter snowfall is much
heavier here than in the interior. The result of all of
this is Prince William sound’s world famous tide-
water glaciers. Though some glaciers in the area are
retreating, the glacial process in the chugach ranges
is far from dead, with at least nine tidewater glaciers
currently advancing as well.
all up, there is little chance that snow will be
lacking in these parts. so the potential for epic snow
adventures is high. as for steepness, it’s also likely to

be in abundance, which is why the chugach is the
holy grail of big mountain lines for ski mountain-
eers. The snow conditions here are due to the area’s
unique combination of sticky maritime air coming
in contact with cold mountainsides, meaning that
exceedingly steep powder lines can form anywhere
the underlying rock provides an opportunity. The
terrain just happens to provide every option avail-
able, producing a range of radical features from
spiny faces to snow mushrooms, ramps, gullies, wind
lips and couloirs, not to mention some good sized
cornices as well. simply put, there are more steep
lines in good condition here than anywhere else on
the planet.
another part of the chugach equation is the qual-
ity of the snow there, and it is by no means perfect.
but with just a single clear night, a surface of slabby
wind-packed snow will be transformed into a sparkly
crystalline layer of completely non-cohesive snow.
This super-fast powder surface skis like a dream.
With disturbance, though, this powder turns into
another famous alaskan beast, the free-running sluff.
Together, these ingredients make for some pretty
unique challenges that will spice up even a modest
ski mountaineering expedition.
To give you a taste of what might be in store, here’s
my friend Tom burt’s mental checklist of hazards he
had in mind prior to dropping off cordova Peak.
1. avalanche on the summit icecap
2. icecliffs below the summit
3. spotting the correct spine onto to the face
4. conditions on the spine
5. escaping the sluff runnels
6. avalanche on the face
7. The lower cliff band
8. The bergshrund
9. The glacial holes at the bottom
10. Tom didn’t mention it, but i gather that falling
on a line like this wouldn’t be advisable either!
Places to go, things to do
an entire snow season in the chugach takes place
over only a couple of months. starting with rapid
snow accumulation and short winter days, the snow-
pack gradually consolidates on steep ground and the
better lines fill in. Then the days lengthen and things
start warming up at an alarming rate. before you
know it, the season is gone, the mountains are shed-
ding, and the glaciers are opening up.
over two seasons in the chugach, with rory camm
and various teams of others, we’ve been lucky enough
to complete trips to several interesting parts of the
region and negotiate just a few of the classic lines on
offer. This includes trips to the western chugach, the
Kenai mountains, the central portion near valdez,
and a boat-based mission out in Prince William
sound. but this sum total feels like a mere scratch on
the surface when i think about what’s out there! For
anyone thinking of heading that way, here’s a selection
of some of the more significant peaks we visited, to
give you a taste of what to expect.
girdwood is a true ski town near the anchorage
end of the range and is a great first stop for any
alaskan winter trip and one of the only options for
riding ski lifts. right behind town there are also sev-
eral imposing faces including the classic northwest
face of big league which has managed to evade us
twice now, despite best laid plans. Further east are
an array of peaks, all approachable from the road
en-route to Whittier and the adjacent Placer valley,
which contains the railway. although there used
to be a ski train here, offering a morning stop and
evening pickup from the rail line, these days you’ll
find the locals concentrated around Turnagain Pass,
which provides the easiest possible roadside access in
these parts.3 However since the snowline is often at
sea level, there are plenty of options right across the
Kenai Peninsula.
Prince William Sound
This season we decided that Prince William sound
might be worth a shot too. The allure of riding to
the water’s edge got us travelling out of Whittier
and into the unknown. all around the large glaciers
above blackstone and the surrounding bays offer
huge terrain, and even apparently insignificant peaks
on the map offer gob-smacking potential. Within
30 kilometres or so it became apparent that we were
looking at what could well be the world’s biggest
terrain park, with the unlikely situation of great sea
access! The place is vast and ridiculously skiable.
on the downside, this area is also renowned for its
storm generating capacity, as demonstrated by the
snowpack which was a solid 2-metres deep, right
down to sea level. We were lucky to get three days
of welcoming conditions, including two days of
sunshine and spectacular views up college Fiord and
into the heart of the chugach around mt marcus
baker. Unfortunately our first outing coincided with
a warm-up that turned the new snow into elephant
snot. We turned back from our planned objectives
above the Tebenkof glacier and gave away our
chance to bag a peak. at least we had spring corn
conditions down near the coast to retreat to, so there
was still plenty of fun to be had.
Thompsons Pass
several hours drive from Prince William sound,
or a short flight east, lie the towns of valdez and
Thompsons Pass. This is one of the few places afford-
ing easy road access to higher elevations. (imagine
the Fox and Franz névés with road access and you
have some idea of the fantastic potential of the area
around the Pass.) The action takes place along a
20-mile (32 kilometre) stretch of road that is host to
several glaciers and the voluminous snowpack that
lies over them. if you’re interested in easily accessed
backcountry powder, moderate sized peaks and
plenty of terrain options, you might not need to go
any further than Thompsons Pass.4

mountain where several peaks with great lines pro-
trude above the névé. We concluded our trip there
with a 10 mile (16 kilometre) ski out to the car, which
we finally located at around 1.30 am—it was hiding
behind a large crowd of people and several bonfires.
our car park turned out to be the spot for the local
prom night after-party so there were plenty of aprés-
ski beers to go around!
leaving chugach on a high note can be difficult;
deciding when to pull out or, worse still, abandon an
expedition is a typical alaskan expedition dilemma.
This year we got lucky with a late expedition to the
Tonsina glacier area in the vicinity of Peak 7601.
after three days camp-bound while the snow came
down, we set about climbing a number of un-named
peaks that offered testing lines. suitably invigorated,
we decided that it was a perfect time to call it quits
and begin the long journey home. The north ramp of
meteorite—one of the premier ski mountaineering
lines in the area—had eluded us for another year. The
story of our attempts to ski the meteorite are typical of
many chugach ambitions; just when we had worked
out how we’d do it, the next storm would come in and
a few days later the place would have changed. it’s all
about seizing your chances in alaska it seems.
valdez has been made famous in ski movies the
world over and is home to several heli-skiing opera-
tions, in addition to cordova and Haines further
east. The area also provides perfect access for sled
skiing so you’ll often find the full range of access
mode skiers all vying for first tracks on anything
in condition. as a lowly non-mechanised traveler
there is no need to despair though—there are many
couloirs and other features with no easy way up and
no landing zone for the heli services. or you can get
up early and start straight up something tasty in the
hope that the local pilots will avoid foot traffic. best
of all, though, is how quickly the people disappear
after the heli season, leaving only a handful of locals
to see in the spring.
There are dozens of accessible peaks and ridgelines
in Thompsons Pass, all full of ramps and chutes, and
we rode a heap of great lines in that area. some of
the best include Python, Diamond, Acupulcho and
Stone. but after some time there you will notice that
the really big stuff lies beyond. The choices become
more arduous or more expensive as you move fur-
ther back from the road corridor. as in new Zealand,
it is possibly to fly into many areas, but coordinating
extraction is not always easy. other choices revolve
around access by snow machine, by boat, possibly by
dogsled and even by kite.
often the good old Kiwi-style expedition base
camp is one of the best ways to spend enough time
in one area to assess conditions and bag a big line.
We used this strategy several times and it really paid
off. in two seasons there our best expedition trip
involved venturing east to the truly ridiculous ter-
rain in the valley of the Tusk. our nine day trip in
the valley of the Tusk resulted in some of the best
ski mountaineering we’ve experienced including suc-
cessful lines off the right and left peaks of the main
headwall. We were spared a confrontation with the
central line off the main ‘Tusk’ thanks to an ava-
lanche that had striped that face back to rock, with
a large chunk of hangfire ominously poised at the
top—that was our excuse anyway!
Bench and Heiden Glaciers
other destinations which produced great multiday
trips include the nearby bench and Heiden glaciers
south of Thompsons Pass. The bench and Heiden
glaciers are home to ‘the books’ and other veritable
libraries of scary lines, mostly in the form of steep
ramps cutting through cliff bands. This year we
also investigated the glaciated terrain beyond stone
