Ritchie Rock (bg|скала Ричи|skala Ritchie, pronounced as /bg/) is the conspicuous rock off the southwest coast of Snow Island in the South Shetland Islands, Antarctica extending 80 m in south–north direction and 73 m in west–east direction, with a surface area of 0.17 ha. The vicinity was visited by early 19th century sealers.[1]
The feature is named after Edward Samuel Ritchie (1814–1895), an American inventor and physicist who created a waterborne version of the theodolite used in harbour surveys; in association with other names in the area deriving from the early development or use of geodetic instruments and methods.
