Occupying 140 acres, Forestvale Cemetery remains in use today. Designed by Vermont native Harry Vespasian Wheeler, a civil engineer, the cemetery was envisioned as a "Rural Cemetery", a style coming into vogue in the nineteenth century.

Founded in 1890 as the Helena Cemetery, Forestvale Cemetery occupies 150 acres (according to current tax records) in the Helena Valley. The name was changed to Forestvale in 1901.
