No trace of a work for piano and orchestra has survived outside Rimsky-Korsakov's recollections, so it is assumed that the score has been lost, or, more likely, that it never existed. In 1866 Mussorgsky wrote to Balakirev expressing a desire to discuss his plans for "The Witches", his informal name for his "Bald Mountain" music.

Bare Mountain (Massachusetts) borders of the town and that it is 8 feet higher. The Five Colleges Library Depository is located on the north side of the mountain, within a subterranean bunker formerly occupied by the United States Air Force Strategic Air Command. Bare Mountain, like much of the Metacomet Ridge, is composed of basalt, also called traprock, a volcanic rock. The lava from which the mountain is formed was erupted in the early Jurassic Period when North America was rifting apart from Africa and Eurasia. The lava welled up from the rift and solidified into sheets of strata hundreds of feet thick.
