	Legend has it that a cow stepped on a thin spot on this overhang and launched the creation of this natural bridge.



	Left and below: the lower end of the gorge.


	Beyond the gorge the valley opens out and there are no more outcrops.
	This waterfall at the upper end of the gorge can have vigorous flow, as seen here, or be completely dry.

	A former hotel and night spot burned out in the 1970's and despite occasional murmurs of interest, has never been rebuilt.
	Excavation of Marribel Caves has extended several hundred feet into the cliff.




	Dolomite isn't as soluble as limestone but there are a few small stalactites.
	And other things hanging from the ceiling.






	The natural entrances to the caves.
