## Cameroni sends Adularia V15
Giuliano Cameroni topped Adularia V15 in Gottardo, Switzerland, a compression problem requiring strong heel hooks and technical toe hooks.
## Cold temps made the difference
At 4°C, the rock grains kept their texture and chalk stayed effective instead of turning soapy. Previous attempts in warmer conditions failed due to greasing off.

> when it's 4°C out, this problem ceases to exist: the rock grains keep their texture and, even after 30 seconds on the wall, chalk stays chalk
## Graham's 2023 first ascent
Dave Graham established Adularia in September 2023, noting the difficulty of finding good conditions in Gottardo due to rain, fog, and heat.

> Gottardo is ultra tricky to find sending conditions considering all the rain, fog, or heat.
## Multiple strong repeats
Stefano Ghisolfi, Sam Weir, Marco Müller, and Jorge Díaz-Rullo have all repeated the problem. Díaz-Rullo topped it in just three sessions.
## Cameroni's prolific record
The Swiss climber has now topped at least 25 V15s and five V16s. He's established many of Switzerland's hardest lines, including REM V16 and Poison the Well V16.
## Three new lines in 2026
Cameroni has already established three hard problems in Ticino this year: Baby Shark V15, Trentatré Trentini V15, and Bim Bam Bum V13/V14.
## Key takeaway

Cold conditions (4°C) can make friction-dependent boulder problems significantly easier by preventing chalk from turning slippery.
