1947 Map of Guadalupe

South of the valley floor, the terrain rises into the Casmalia Hills and Point Sal Ridge, where the northern edge of the Camp Cooke military reservation dominates. Local history is preserved in the location of rural schoolhouses like Bonita School and Betteravia School, alongside the industrial site of Betteravia near the shores of Guadalupe Lake. A notable military detail includes an Abandoned Firing Range north of the river, suggesting the area's strategic use during the preceding years.
