We went back to the Dolomites (our second time there after a guided tour with BlueSky in 2010, http://bcwetcoast.blogspot.ca/2010/10/dolomiti-italy-oct-4-9.html).
A stunning area to fly with its tall limestone towers and snow covered
peaks. But due to the huge crowds and strong conditions its also a risky
area. Anybody who wants to fly there should be on their game and do
some homework before the trip. There are amazing videos and pictures of
flying in the Dolomites on the internet, but it takes special conditions
for a flight like this and they are as rare as a powder day on the ski
slopes.
It took us two trips to hit one of the stellar days. Too much north wind
the day we arrived. We did a couple of short flights from Belvedere at
Pordoi Pass (last day for the lift there to be open). Stronger north
wind was forecast for the next day so we headed to Bassano for more
relaxed flying (2h drive on narrow windy/winding roads over passes and
through spectacular limestone gorges). Third day was one of the ‘powder
days’. Pete launched from Belvedere, worked hard to get up and scored a
sweet flight over Marmolada, Langkofel and Sella http://www.paraglidingforum.com/leonardo/flight/830365.
Due to driving logistics, I launched later from Col Rodella, where the
air was crowded as usual. I also ran into another Canadian (he was wearing a 2012 Pembi Nationals T).
The next day the conditions changed again. Southwest wind this time. The
inversion took a long time to resolve. We managed to launch earlier
than most from the afternoon (south) take-off at Col Rodella, but were
soon thermalling with about 200 of our ‘best friends’. Wind on launch
increased and got gustier. Clouds were forming and lowering below the
peaks of the Langkofel Group. After an hour in the air and seeing one
pilot take a big frontal in the lee of Col Rodella and rapidly disappear
behind it and another wing spread over the rocks at the bottom of the
Langkofel I had enough and landed in strong valley wind. Pete soon
followed. After we had packed up and walked out, another pilot crashed
in town, behind a house just meters from where we walked. Thankfully
ambulance and advanced medical services arrived quick and in full force.
In total there were 5 or 6 serious accidents on this one day (more
about this day on Paragliding Forum http://www.paraglidingforum.com/viewtopic.php?t=59504).
Strong north wind the next couple of days, so we left our wings in the
bags and explored some of the hiking trails and via ferratas. The latter
are climbing routes equipped with cables, ladders and metal rungs
originally built during WW1 for soldiers to move safely in steep
terrain. They have become very popular all over the Alps and allow
access to spectacular and exposed terrain (with some minimal climbing
skills, a climbing harness and a couple of special slings). Despite the
strong wind there were still several pilots in the air and we watched
more close calls in the LZ where a strong wind gradient set up in the
afternoon (one 70% collapse 50 meters above ground, one very bad tandem
landing, and other less spectacular mishaps). Just 15 minutes later the
wind died and another group of pilots landed in smooth conditions not
knowing what they missed while the guy with the collapse was still pale
(and hadn’t even had time to change his underwear).
End of the trip report, but since it’s been raining ever since we got
back I had some time for more musings & ramblings. Hopefully more
info about the conditions will reduce the strain on local ambulance and
rescue teams… and on the local flying community … just imagine our sites
would be invaded by 300-400 pilots for a couple of weeks each year!
Prerequisites for flying the Dolomites:
- Being comfortable in strong thermal conditions (think Pembi or even Golden).
- Good crowds flying skills (talking about >100 pilots in the house
thermal) and solid nerves to fly with others who are in over their head
and react unpredictably. IMO crowding is the biggest safety concern.
- Ability to identify wind directions in complex valley system and avoid associated lee/rotor areas.
- Healthy resistance to lemming effect. Others launching and flying does
not mean it is ‘fly-able’. Bring along several plan Bs: there are tons
of spectacular hiking trails, via ferratas of various difficulty,
mountain biking. Most days flying is possible in Bassano. Lots of
cultural activities too; museums, old houses, delicious grappa and
cheeses to sample.
Observations/condition at Col Rodella (disclaimer: this is from a two-time visitor, no warranties on completeness or accuracy):
- Generally two competing wind systems, one over the Sella Pass from
northern Val Gardena/Grödner Tal (north wind at Col Rodella) and the Val
di Fassa/Fassa Tal wind (generally builds after noon, south/west wind
at Col Rodella launch). Depending on general wind conditions these winds
may compete during the day and can lead to variable and unpredictable
conditions.
- Use the east launch in the morning then move over to the south launch
in the afternoon as the Fassa Valley (southwest) wind takes over and the
bowl in front of the east launch is in rotor. Famous videos of dust
devils twisting up wings are from the east launch in lee conditions.
- North wind is bad (anything more than light wind) and creates big
lee/rotor zones or problems lower down, even if the south launch is not
affected. On the evening of one of our plan B days there was a strong
shear layer 50-100 meters above the main LZ with strong N-N/W above and
strong S below (our hypothesis was that it was generated by the north
wind dropping down over Sella Pass, hitting the high ridge south of the
LZ and being redirected just above ground level).
- West/Southwest wind can also be dangerous as it increases the already
strong afternoon Fassa valley wind. This wind funnels up into the side
valley west of Col Rodella and makes for bad rotor in the lee (behind
lower canyon ridges, the Col Rodella cliffs, etc). This can also produce
strong and gusty wind in the main LZ which thankfully is very large.
These were the conditions on the ‘carnage’ day.
- Although the meadows near launch look inviting, top landings can be
hard and cause severe injuries due to lee/rotor areas (a couple of days
after our first visit a German champion pilot top-landed behind the
south launch and broke his back).
- Worst days are the ones with some lift but strong inversions when
nobody gets away and most bumble around at the top of lift. It may be
possible to fly in relative solitude by staying below the crowds.
- Last but not least, this should be a no-brainer, get out of the way of rescue helicopters, even if other pilots don’t.
