Evolution of the Neale Burn Drainage, Fiordland, New Zealand

Caption

A numerical model provides snapshots every 250,000 years of the evolution of the Neale Burn drainage in Fiordland, New Zealand, during the last 2.5 million years. Over this time, the glacier cut into the flanks of the mountain at the mouth of the drainage, and later cut further toward the headwaters. The white line in the upper panel is the centerline of the Neale Burn valley, while the dots show the location of elevation profiles referred to in the lower panel. The middle panel shows the local lowering rate (i.e., erosion rate minus uplift rate) along this profile, as calculated for the preceding 250,000 years of each time frame.
