THUNDER MUSCLE ( 5.14A), SEAL ROCK
Climber: Isabelle Faus
First ascent: Matt Samet, Ted Lanzano; 2013
In 1989, Chris Beh, Chip Ruckgaber, and Colin Lantz installed anchors atop this route with every intention of returning to bolt it, but then the hardware ban was imposed days later. The trio certainly had an eye for a line— Thunder Muscle feels like a limestone tufa route from Spain or Kalymnos transposed onto Flatirons sandstone. While the moves are bouldery and fierce, the route has two good rests: one at the “heart” at one-third height, and the other a no-hands before the upper 5.12c funkfest. In 2016, Daniel Woods flashed the line, giving it French 8b on his Facebook page— ooh-la-la, eez nice to be zo strong!
