Stage 20 of this year's Tour de France may have failed to make it over the Cormet de Roselend due to mudslides, but a few days later the pass was clear again, and I stopped overlooking the Lac de Roselend on the way up from Beaufort (doing the excellent Bourg-Moûtiers-Albertville-Beaufort--Bourg loop).
Fortunately the temperature had cooled a bit from the 41C my Garmin recorded in shade in the Isère valley the week before.
