The bus slides out of Mendoza before dawn, vineyards thinning to scrub as Route 40 unfurls southward. By mid-morning the high plain gives way to the Atuel River’s work: a canyon cut into layered sandstone and volcanic tuff, walls striped ochre and rust that catch the sun and seem to move as you approach.
