The Riders of the Whistling Skull

The Three Mesquiteers accompany an archeological expedition to a lost Indian city of gold called Lukachuke in a mystery western full of humour, intrigue and rollicking action, especially at the end with a landslide. It's called a horror-western but apart from the cursed lost city there isn't much horror. What there is is great landscape, a well-designed lost city and plenty of fun. Definitely top tier of its type.
