Snow Wood Boarding School is a large boy's boarding school in EarthBound located in Winters, Foggyland. Jeff Andonuts lives and goes to school here until he gets a telepathic summons from Paula after she and Ness are trapped under a graveyard in Threed. To the south is a large snowy forest, beyond which Jeff finds Lake Tess. It cannot be revisited after Tony helps Jeff escape the premises.
