Several old plat names on lake shores around Big Stone Lake and Hartford Beach — Linden Beach, Madsen Beach, Dahlberg, Diamond, Hammer, Long Hollow, Rudebusch Corner, Schmidt Landing, Valley View Estates and Victor — are small platted subdivisions or seasonal-cabin clusters rather than towns with any government or ZIP of their own; they are not carried as separate rows here.<\/p>\n
