The upper part of Hasselwood Rock is the destroyed cone of an extinct volcano, 200 metres (656 feet) north of the larger outcrop of Rockall.[1]
The rock is approximately 1 metre (3ft 3in) above low water, and 13 metres (43ft) in diameter, with an area of approximately 130 square metres (1,400sqft). It is covered at high tide and in heavy seas, often only visible as breaking waves. There are no sources of fresh water on the rock, which is uninhabitable. The only other rocks in the area, those of Helen's Reef, are almost 2 kilometres (1.2mi) to the north-east.
Expeditions and landings have not been reported. The geological composition is unknown.[1]
