Ponderosa Pines is a census-designated place (CDP) in Gallatin County, Montana, United States. The population was 336 at the 2010 census.[2] Formerly a 13,000-acre ranch, the land was subdivided into 10- and 20-acre parcels and sold by a Hawaiian real estate agency starting in 1972. The lots lacked water, sewer, electricity and road access, and some were on such steep terrain that building would be impossible.[3]
Most of the CDP is in the Three Forks Elementary School District and the Three Forks High School District. A small portion is in Pass Creek Elementary School District and the Manhattan High School District.[4] The Three Forks elementary and high school districts are both a part of Three Forks Public Schools.[5] The Manhattan high school district is a part of Manhattan Public Schools.[6]
