El Salto de Juanacatlán on the Rio Grande de Santiago River is situated in the south-east of the city Guadalajara in west-central Mexico (Jalisco state). The waterfall was considered to be the second largest in North America (in terms of volume and flow) after the Niagara Falls.
Despite its former fame, the about 35-meter-high and 160 metres wide horseshoe-shaped El Salto de Juanacatlán was reduced in the 1980s to a trickle of dirty, evil-smelling effluent from local factories.
