The detection of a large molecular cloud at a distance of more than 200 pc from the Galactic plane, situated above a prominent hole in the CO distribution in the plane, is reported. The cloud has a radial velocity of -41 km/s, much larger than is characteristic of most local, high-latitude gas. The cloud's displacement above the plane is the largest for any cloud yet detected. The mass of the cloud is about 100,000 solar masses, and its gravitational potential energy is about 7 x 10 to the 50th ergs. A single event may have created both the cloud and the nearby hole. 27 references.
