On the grassed plateau above the estuary channel stands a stone memorial to the founder of Riverton, whaler and runholder, Captain John Howell, who, while in the employ of Johnny Jones, was dispatched with three ships to establish a whaling station at Aparima in either 1835 or 1836 to replace the abandoned station at Preservation Inlet. The settlement became known as Jacob's River due to a local Maori living at the mouth whom the whalers called Jacob. Jones's purchase of all that land from Colac Bay to the New River, and extending some fifty miles inland from the Ngāi Tahu chief "Bloody Jack" Tūhawaiki was formally acknowledged in October 1838.
