The company also produced several utility based vehicles based on their snowcat tracked vehicle, in addition to larger snow grooming machines suitable for use on steep ski-slopes. Thiokol machines were used in ski resorts, operated by the USAF in Alaska and other northern regions, and are now popular with private owners as dependable snowcats and for all-terrain transport.
