of Levencorroch Burn, 3.219 km. north-west of Kildonan Castle, Buteshire
A small dolerite sill intrusive in Triassic sandstone is seen retarding
denudation and giving rise to a waterfall. A man is seen standing
by the waterfall.
The fall is formed because the outcrop of resistant dolerite is
underlain by weaker rocks, the latter are worn down at a faster
rate, begin to undercut then as the face of the resistant rock becomes
vertical the stream plunges over to form a waterfall. Eventually
the waterfall will degrade into rapids before it is smoothed out
entirely.
