Wind-blown dust

Wind-blown dust

North-west winds lift dust from the Dart riverbed at the head of Lake Wakatipu. This fine dust can be carried hundreds of kilometres to the east, and deposited as a layer of silt, known as loess. In leeward (eastern) parts of the South Island, many fertile soils have formed from loess – blown from riverbeds in the great outwash plains of past glaciations.
