Water sinks in Watlowes Valley

Watlowes Water Sinks At the northern end of Watlowes Dry Valley on route to Malham Tarn, you see the stream from Malham Tarn disappearing underground.  This locality marks the point where the stream stops flowing over the Lower Palaeozoic basement rocks and begins its route over Carboniferous limestone.  The stream has no difficulty finding the joints and cracks from which it can begin its decent underground.  Surprisingly enough, the water disappearing at this locality does not appear below Malham Cove.  On the contrary, it next appears at the surface at Aire Head Springs (where the shales and mudstones of the Bowland Shales prevent the water from continuing its route underground).
