Khalzan uul rashaan suvilal—Bald Mountain Mineral Spring Sanatorium—in Mongolia offers sulfurous and ferruginous mineral spring waters in one of Central Asia's most extensive and geologically varied thermal spring landscapes, where the volcanic geology of Mongolia's Great Lakes Depression and the surrounding mountain systems produces mineral springs of genuine mineral character in a landscape of extraordinary Mongolian steppe, desert, and highland diversity. The Mongolian rashaan (mineral spring or holy water) tradition holds a place in the nomadic culture somewhat analogous to the Japanese onsen tradition—natural mineral springs are sought for rest and well-being, associated with sacred or auspicious natural forces, and visited seasonally within a long bathing tradition. The sulfurous and ferruginous mineral combination gives the water a distinctive dual character—the hydrogen sulfide of the sulfurous component and the iron-rich character of the ferruginous component—in a Central Asian sanatorium tradition that adapts Soviet-era bathing infrastructure to Mongolia's genuine geological spring resources.
