The settlement of Lasauses serves as a focal point in this 1960s survey of the San Luis Valley, where the Rio Grande and Conejos River converge. This landscape is defined by its complex hydrology, featuring numerous flowing wells and the man-made Conejos Diversion cutting across the alluvial plain. The eastern portion of the sheet is dominated by the volcanic terrain of the Sangre De Cristo Hills, while the northwestern corner preserves the marshlands of the Alamosa National Wildlife Refuge. The map traces early land divisions through a prominent Grant Boundary and includes the small, family-oriented Becker Cem near Hansen Bluff, providing valuable data for genealogists interested in the early ranching and agricultural communities of Costilla County. Meandering watercourses like Trinchera Creek illustrate the historical importance of water management in this arid high-altitude region.
