1966 Map of Devore

Evidence of mid-century infrastructure and land use is visible in the development of the Barstow Freeway and the presence of specialized facilities like the Glen Helen Rehabilitation Facility and the Gilfillan Airport. Toward the southern edge, the grid-iron street pattern of Rialto begins to take shape, featuring landmarks such as the Rialto Municipal Airport (Miro Field) and local institutions like Kolb Jr High Sch, illustrating the era's suburban and industrial expansion into the San Bernardino valley.
