This early phase of mountain growth is exemplified in the Finisterre Mountains of Papua New Guinea, a propagating growth fold whose catchments can be observed at a range of stages in their temporal evolution. Watersheds appear to initiate by isolated gorge incision, to expand by large-scale landsliding in a manner controlled by ground-water seepage, and to entrench by fluvial incision of landslide scars and deposits. Once a montane system of ridges and valleys is established, only rare, major landslides can modify the drainage pattern. The steady-state morphology of a mountain belt is therefore intimately related to its initial phase of growth. This content is PDF only. Please click on the PDF icon to access.
