Story: Nelson region

Lake Rotoiti

Lake Rotoiti

The landscape of much of Nelson Lakes National Park, which lies on the eastern side of the Alpine Fault, resembles Canterbury’s mountains, due to recent glaciations and the underlying geology of greywacke which weathers to form distinctive scree slopes. Lake Rotoiti is the smaller of the two large glacial lakes in the national park. These formed when rivers were dammed behind past glaciers’ terminal moraines (ridges of rubble that form at the front of a glacier).
