Glaciation in the Taramakau valley

During glacial periods a major glacier extended down the Taramakau River valley. This map shows the extent of the glacier in the later part of the last glaciation, about 18,000–20,000 years ago. Alluvial gold was concentrated in river gravels in front of the glacier, and one of the richest areas was near Kumara. Click on the thumbnail to see a photograph of the Kaniere dredge working these gravels.
