... and landscape evolution, we focus our study on landforms within the valleys of the Khumbu Himal region, south of Mount Everest ( Figs 1 and 2 ). The region was chosen because it is relatively accessible and has well-established glacial chronologies, and contains abundant impressive fans and terraces...

... for their detailed and constructive review of this paper. The relatively small amount of lowering of the equilibrium-line altitude on the Khumbu Glacier relative to the present (200–300 m) indicates that the Khumbu region also may have experienced a reduction in precipitation. This could reflect a shortening...
