Hubbell died in AD 1930, and his youngest son, Roman Hubbell, assumed management duties. The stone Hogan(cottage) was constructed by Roman and his wife Dorothy in the early AD 1930s as a memorial to the elder Hubbell. Upon Roman's death in AD 1957, Dorothy maintained operations until AD 1967 when the National Park Service acquired the homestead. Hubbell, his wife, three of his children, a daughter-in-law, and a granddaughter are buried on the cone-shaped hill northwest of the trading post. Many Horses, son of Ganado Mucho, is also interred at this Hubbell family cemetery.
