Princes Street, north-east from Stanley, Falkland Islands, is a stone run measuring up to 4 km long and 400 m wide. It consists of thousands of boulders of hard quartzite rock, mostly between 30 cm and 2 m across. They formed during the last Ice Age as a result of intense freezing and thawing actions.
It was named Princes Street by Charles Darwin, who first brought this type of formation to the attention of the scientific community after visiting the islands in 1833 and 1834 and describing it in his second edition of his Journal of Researches (1845).
