Hotel Puente del Inca: A former hotel beside Puente del Inca, built near the site’s hot springs and later damaged by an avalanche. Its ruins show how people built around the springs before a destructive avalanche.
Carbonate precipitation: The formation of solid carbonate minerals from aqueous solutions. Dissolved minerals precipitated around the springs, cementing deposits onto the site.
Las Cuevas River: A mountain river in western Mendoza, Argentina, near the Chilean border. The river runs beneath the arch and helped shape its setting.
