Nevado del Plomo, Mountain summit at Argentina-Chile border in Principal Cordillera, Argentina.

Nevado del Plomo is a mountain summit in the Central Andes on the Argentina-Chile border, rising to 6,070 meters. The peak is marked by the Juncal Sur Glacier on its western slopes and features technical climbing routes for ascents.

The mountain was first climbed in 1910 when Friedrich Reichert, Friedrich Bade, and Robert Helbling ascended the northern ridge. This marked the beginning of the peak's recorded mountaineering history.

The mountain marks a natural border between Argentina's Mendoza province and Chile's Cordillera region. This position makes it a meeting point between two distinct Andean landscapes and communities.

The best climbing season runs from late spring through early autumn when conditions are most favorable. Visitors should prepare for technical challenges and check local requirements before attempting the ascent.

By 2019 only 16 ascents of Nevado del Plomo had been recorded, reflecting the three-day approach over 22 km of moraines and 3,500 m of elevation gain. The southeast face, climbed in 2003 by German climber Jurgen Straub via the "El Sendero del León" route, is rated very difficult.
