Its surface area is 0.08 ha (0.20 acres). The vicinity was visited by early 19th-century sealers.[1]

The feature is named after Jonathan Sisson (1690–1747), a British instrument maker who invented the modern theodolite for surveying; in association with other names in the area deriving from the early development or use of geodetic instruments and methods.
