New cat named ‘Nimbus’ settles in on Mount Washington Modified: 5/6/2021 6:17:18 PM NORTH CONWAY, N.H. — There’s a new feline prowling about the highest peak in the Northeast. Nimbus, a gray shorthair who shares his name with large, gray clouds that bring precipitation, has been a resident at the Mount Washington Observatory since April 14. The observatory staff have had a cat at the 6,288-foot summit, called the “home of the world’s worst weather,” since 1932. Nimbus succeeds Marty, a black Maine coon cat who became ill and died last fall. Rebecca Scholand, the observatory summit operations manager, began the search for a new cat with the help of the Conway Area Humane Society. Nimbus was transferred to the humane society from an animal rescue group in Oklahoma.
