Supercrack on Aguja de l'S, a 400m freestanding tower in the Guillaumet group near El Chaltén, delivers pure crack climbing at 5.11 (6c+). Eight pitches of perfect parallel cracks demand finger strength. Approach from Niponino basecamp via 5-hour glacier hike. Less crowded than Fitz Roy, but equally committing. Practice Leave No Trace; minimize fixed gear.

Follow UIAA remote climbing guidelines: partner checks, avalanche awareness even off-season.
