The new record has huge implications on altitude highlining, it means that the final frontier now is the Himalaya, since this is one of the highest possible lines in the Andes mountain range! There remains the possiblity to rig a line on Aconcagua, the highest mountain in South America, but since this a very commercial mountain the permits are expensive.

The Highline Altitude World Record has been broken by a large margin, now standing at 6880m above sea level. Congrats to the Chilean Crew involved and to Matías Grez (Chile) for sending the line on the 21st of December 2022 on the highest volcano in the world at the border from Chile to Argentina.

Detailed Specs:

Height above sea level: 6880 m
Length: 33 m
Height: 20m
Location: Nevados Ojos del Salado, Región de Atacama, Chile, https://slackmap.com/x/s0H32cW2EUqjq
Setup: Balance Community Lift2be
Videographers and Riggers Crew: Matías Grez, Rodrigo Flores, René García, Claudio Echegaray, Bernardita Lira 

Check out the comments we got from them:

This highline was part of a project that took 5 months. In the first stage we lived in San Pedro de Atacama (2500m), where we started climbing the volcanoes of the area to train. We installed a highline of 115 meters length in the summit of Lascar (5592m), to achieve this we had to climb it 3 times. Then in Licancabur summit (5916m) we installed a 95 meter long highline, for this we had to climb it 4 times, and sleep 2 times in the crater. Finally we had to live 1 month at the base of Ojos del Salado volcano (6893m) and climb it 3 times. It was on December 21st when we installed the highline at 6880m and could walk it. The crew was a chilean group composed by:
Lascar Volcano: Matías Grez, Moisés Castro, Diego Troncoso, Bernardita Lira
Licancabur Volcano: Matías Grez, Rodrigo Flores, Bernardita
Lira Ojos del Salado Volcano: Matías Grez, Rodrigo Flores, René García, Claudio Echegaray, Bernardita Lira 

The Female Highline Altitude World Record has been broken, most likely still standing at 5250m above sea level, rigged on and to a glacier over a glacial lake. Congrats to a Bolivian-Italian Crew involved and to Miriam Campoleoni (Italy) for sending the line on the 31.08.2021 over Chachacomani-Glacier in Bolivia.

The Project was part of a research project on the Chachacomani-Glacier in cooperation with the Servizio Glaciologico Lombardo, Turismo Rural / Peñas and La Cordillera Experience Peñas.

Detailed Specs:

Height above sea level: 5250 m
Length: 50 m
Height: 20m
Location: Chachacomani-Glacier, Near Chachacomani Peak, in the Cordillera Real of the Andes Mountains, east of Lake Titicaca in Bolivia
Setup: Spider Slackline Zao
Anchors: Two Abalakovs threads on each side, plus an ice screw on one top and a snow mushroom on the other (Fully anchored to the ice)
Riggers Crew: Miriam Campoleoni, Daniele Assolari and Rodrigo Lobo Villarroel
