View from Gordale Bridge or proceed as a side trip into Gordale Scar. The spectacular gorge in the Malham Formation was probably carved as a meltwater channel beneath the Devensian ice-sheet. Upstream of the waterfall the gorge dog-legs abruptly to the northwest, where a series of minor extensional faults have controlled the erosive path of the meltwater channel. These faults are exposed just above the tufa screen and are part of the complex set of fractures between the North and Middle Craven faults. The superb Malham Formation section in Gordale Scar exposes 43 m of the Cove Limestone Member and 94 m of the overlying Gordale Limestone Member. This location is designated as the stratotype for the latter. The contact of the two formations is a strong bedding plane defining the top of the first persistent scar feature.

Take the footpath which leads south from Gordale Lane into Gordale Beck. The footpath enters a wooded valley where the stream is interrupted by a small waterfall (Janet's Foss) below which is a moss-covered tufa screen. This exposure of Gordale Limestone forms the northern part of the hanging wall block of Wedber Brow. These limestones dip east-northeast at 25° towards a fault defining the eastern margin of the Wedber block. The middle and southern parts of Wedber Brow are formed by 'reef' limestones. The small cave known as Janet's Cave was, according to records, inhabited in the late 17th century by smelters working the copper mines at Pikedaw to the west. The exposed Gordale Limestone above the waterfall is notably mottled as a result of the burrowing activities of bottom-dwelling organisms. This burrow-mottling can be seen in exposures in the path on the return to Gordale Lane.
