[5] Several teams had attempted to summit Annapurna III via the southeast ridge, with all efforts prior to 2021 ending in failure.

[6] The first attempt up this ridge was in 1981 by Nick Colton and Tim Leach who reached about 1000 feet below the peak before turning around.

Twice in 2010, Pete Benson, Nick Bullock, and Matt Helliker unsuccessfully attempted the southeast ridge.

The route was considered one of the unfinished challenges in the Himalayas and is about 2,800-3,000 meters on a vertical face whose crux emerges in the form of a technically demanding chimney shown in the video of the 2016 attempt.
