This section can be rafted and kayaked. They rafted logs down river to Hoist Bay until 1929. Iceberg rafted glacial erratics and erosion features are evidence of these events. It was built of kauri logs rafted from Mercury Bay on the Coromandel Peninsula. Sections could be supported over marshy ground on rafted or piled foundations. The Overlanders expedition to the Cariboo goldfields rafted down the North Thompson River in 1862. They have been attributed to rafted slabs of solidified lava floating on a still-molten subsurface. There are also bigger (sometimes glacier-fed) rivers which are sometimes rafted. The first settlers rafted down the Ohio River in 1788 following the American Revolutionary War. From there, prospectors generally rafted to Dawson City, Yukon. Presently, few logs are ever rafted.
