2016 Map of San Isidro

About this map

San Isidro and Delmita anchor this rural landscape in the Rio Grande Valley hinterlands, where the ranching heritage of South Texas is clearly inscribed across the terrain. The map reveals a dense network of family and community history, evidenced by an exceptional concentration of private and parish burial grounds. From Santa Elena Cem in the northwest to Gonzales Cem in the southeast, these sites often correlate with historic land grants and family estates. The road system, including Rich Road 1017 and FM 1017, connects these scattered settlements and cemeteries, while the eastern boundary tracks the transition from Starr County into Hidalgo County. The land is defined by winding tracks like War Loop and Old Church Rd, reflecting a settlement pattern based on ancestral ranching tracts rather than a rigid urban grid.
