Argentina’s late-July snow closed two separate Andean accounts. Official status pages listed both the Cristo Redentor system between Mendoza and Chile and Catamarca’s San Francisco pass as closed on Monday. [E1][E7] Cargo became stationary inventory on one corridor while rescue and supply work continued on another.
About 600 trucks were stranded near Uspallata on 22 and 23 July after Cristo Redentor had been blocked for nearly a week. [E2] Authorities had evacuated 42 people from Puente del Inca, Penitentes and Polvaredas into Uspallata two days earlier. [E3] The town became a holding point for drivers, residents and the agencies deciding when Route 7 could safely climb again.
Catamarca carried a different balance. A multi-day operation recovered 23 tourists and mining workers stranded in the Puna. [E4] The provincial government sent extraordinary support to Antofagasta de la Sierra for forage, food and related supplies, shifting part of the waiting cost onto the public account. [E5]
Industry stopped where the road stopped. Rio Tinto suspended work at the Fénix and Sal de Vida projects until conditions were safe. [E6] The official San Francisco page still showed preventive closure because snow had accumulated on both the Argentine and Chilean approaches. [E7]
No official source in the retrieved record certified a national snowfall record. Standing pass closures, rescues and supply protocols are designed for a strong Andean winter, and they were functioning. The boring case is a severe but seasonal interruption whose queues clear with the next safe weather window.
Delay still has an owner. Truck operators hold cargo and equipment in place; mining companies lose scheduled work; provincial authorities move food and forage to communities cut off from ordinary replenishment. The ledger starts moving again with the first convoy through the pass.
