Location: South 41.10452, West 072.49563 (GPS on the summit)
Difficulty: PD+
Climbed January 25. 2015.
Information:
How to get there: The mountain is right next to,
and east of the big Lago Llanquihue. From the tourist town of
Puerto Varas, drive about 50 kilometer northeast (Chile 225) along the lake to Ensenada. In Ensenada, fork left,
then shortly turn right onto the road that serves Volcan Osorno and its ski area. This road is well signed.
Continue steeply uphill on a good, paved road until it ends.
The parking is right below a cafeteria at location S41.12808, W072.52927, elevation about 1200 meter.
This is a quick summary and reference to climbs made on this trip.
Red Tape:
Almost all parties climbing Osorno does this with a local guide, however, one may do
this independently with a permit from the local Conaf office.
Thus, one should register your climb with the local Conaf office. This is located below (left when facing
the mountain) the main parking area. One can drive directly to the office by turning left on the road
signed for Refuguio Teski, immediately before the main ski area. The office is located on the left hand
side of this road beyond the refugio.
A paper form must be filled out (including your blood type!), however, the main criteria still
seems to be that you can show that you have adequate equipment for the climb. The most essential
items being a climbing rope, crampons, ice axe(s), ice screws and snow anchors / snow stakes.
Route description:
Do not hike uphill on the path below the ski lift. Rather, start out on the service road that starts
out from the Conaf office. This road climbs left (when facing uphill), then zig-zags nicely to
reach a parking area just below the top of the upper skilift. If you have a 4WD vehichle, you should
check with Conaf if you may drive up to this point. (We never did, assuming that this was indeed not
possible.)
A clear path continues uphill, skirting the top lift on its left. From here, the path continues up
along a moraine ridge that should be followed all the way to its end (top). The path is pretty good
despite the common volcanic, loose material. the top of the moraine is about 2060 meter at location
S41.10710, W072.51092.
From the top of the moraine, the rest of the route is pretty clear. Ascend more or less straight
uphill on this face directly to the top.
There are some rocks extending from the glacier
to your right. The first part is
up on a gentle slope. This slope steepens considerably (about 25-30 degrees) in the middle
section. Finally, there is the upper, steep part. This can be climbed in two pitches with
a 60 meter rope. The exact route may change a bit from year to year, there are some
seracs and often a short, final wall that must be negotiated. The last pitch is steep
snow/ice up to 55 degrees.
Above the final "wall", the terrain immediately turns
into a very gentle slope that continues
to the very top. The highest point is immediately on the edge of the very steep (north) slope.
Care should be exercised here as there could be a cornice or unstable snow at the very edge,
stop (at least) one meter from the sharp edge.
Note that the conditions and the level of difficulty of this route may change quite a bit, depending on the local
conditions.
It is likely easier in the early season when the guided parties will establish a track in the snow.
As the summer progresses, the snow typically turns more and more icy. When we were there, one
could not see any specific track, but a fairly natural route, more or less directly up the slope,
seemed to be the choice of
all (4) parties on the mountain that day.
Comments:
We got up around 0515 and departed from our "base" in Puente Varas shortly thereafter.
No other cars in the parking lot when we arrived at the ski area shortly before 0700.
We started uphill at 0700, following the track
under the lower skilift. Soon, the footprints
turned more left, but as we got higher the route became unclear. We traversed a bit right on
loose ground, then headed uphill on what looked like a local hill. On top, we discovered two
parked SUVs. It became clear that a drivable road existed left of our ascent route.
The remaining trail to the top of the moraine was clear and we overtook 2 guided teams on our
way up. We made a short break at the top of the moraine,
a carpet of clouds was below us and the view
was already quite outstanding.
We could see one team already high on the steeper part of the volcano,
as we stepped onto the icy glacier
shortly after 0900. The climb was easy
in the beginning, an icy glacier surface giving
pretty good crampon conditions.
We noticed that the cloud carpet was slowly
ascending as well, but keeping respectfully below us.
Higher up, more care is needed and we stopped and decided to
protect the last 100 meter with our rope.
Cutting through icy crystals, I initially tried to place
an ice screw. However, even below the top surface, the ice was poor and not suitable for a screw
placement. We carried two (deadman) snow anchors and decided that they would have to be used.
Pål Jørgen quickly advanced up the first rope length
placing one anchor along the
way. The second pitch was steeper,
in fact steeper snow than Pål had ever climbed before.
It was nice to see him climb up the final, steep wall and establish himself out of view. I followed,
speaking briefly to the first party where the guide was lowering his two clients down the upper
pitch. It turned out that he had also spoken to Pål, remarking that we climbed in
"traditional style" (meaning only one ice axe). The other guided party that came up behind me,
climbed with each climber using two short axes.
We arrived at the summit at
1145, blue sky all over, with some clouds below -
and a very good view in all directions.
This is certainly a very nice summit and we enjoyed the views
and the place for a full half hour
before starting back down.
We reversed our route rather carefully, got back
down to the moraine and continued down the trail, then
road after a short break to rearrange gear. We arrived back at the car by
1525, a total time of 8.5 hours including the time on top.
Returning to Puente Varas, a nice dinner was in the cards, then preparation for our last Ultra
on this trip, Volcan Calbuco.
The weather forecast was not ideal, but we decided to give
it a try with a very early start the next mornning.
