About this map

San Ysidro sits at the confluence of the Rio Salado and Jemez River, serving as a gateway to the diverse high-desert and mountain landscapes of Sandoval County. The eastern portion of the survey is dominated by the Jemez Indian Reservation and the southern reaches of the Nacimiento Mountains, featuring prominent landmarks like Pajarito Peak and Rabbit Flats. A striking historical marker of the region's industrial past is the Santa Fe Northwestern (Abandoned) railroad line, which once navigated the difficult terrain near the Guadalupe Box.

Westward, the landscape shifts into the expansive Ojo Del Espiritu Santo land grant, a terrain defined by numerous arroyos and essential water sources such as Chamisa Vega Spring and Soda Spring. The presence of CCC Camp No 8 N reflects New Deal-era activity in the region, while isolated homesteads like Rincon Ranch and Marquez Ranch highlight the sparse ranching settlement patterns of the late 1930s. Ancient history is also present, marked by a recorded Ruin near the Bernalillito area.
