The 20-year-old Japanese climber has now achieved the fifth ascent of the line in Colorado. For Kayotani, it is his first boulder problem graded 9A – although this grade has been under discussion since Yannick Flohé's proposal to downgrade it to 8C+.

Sixteen-year-old American Beckett Hsin has repeated "No One Mourns the Wicked" (9A) in Colorado, one of the hardest boulder problems in the world. He is now the youngest boulderer ever to achieve a 9A ascent.

British climber Hamish McArthur is causing a stir in the international climbing scene: He succeeded in completing the second ascent of the 9A boulder No One Mourns The Wicked in Thunder Ridge, Colorado – in just one session.

At the end of last year, Nathaniel Coleman made the first ascent of the 9A boulder No One Mourns the Wicked. The line is the low version of the boulder Defying Gravity (8C), which was long considered impossible.
