Cader Idris I
Originally called Crater Lake, Cader Idris is a synthesis of geometry and landscape inspired by the Richard Wilson painting of that name at the Tate Gallery. Water collected in an inverted cone forms a circular pool, and this spills onto part of a shallow cone.
The kinetic effect of two simultaneous water movements, one flowing down and inward and the other fanning out, alludes to the processes one can observe in nature. High lakes which form natural reservoirs collect water from surrounding mountains and channel it down through waterfalls and streams to the valleys beneath.
