"The Runaway Skyscraper" is a science fiction short story by American writer Murray Leinster, first appeared in the February 22, 1919 issue of Argosy magazine.
"The Runaway Skyscraper" concerns Arthur Chamberlain, an engineer who works in a midtown Manhattan office building called the Metropolitan Tower.
When the subsidence finally ends, the building is located several thousand years in the past, and its 2000-odd inhabitants find themselves stranded in pre-Columbian Manhattan.
Chamberlain convinces the president of a bank on the first floor that he can return them to the present, and together they are able to organize the other inhabitants into hunting and fishing parties.
He forces a jet of soapy water into an artesian well beneath the building, and this allows the pressure that has built up in the rock to be released.
