About this map

The Organ Pipe Cactus National Monument dominates this international border region in Pima County, where the desert floor rises from the broad La Abra Plain into the sharp relief of the Puerto Blanco Mountains and Cipriano Hills. The landscape is defined by its arid hydrology, notably the Aguajita Wash which drains the northwestern corner. The international boundary between the United States of America and Mexico cuts diagonally across the southern portion of the sheet, followed closely by the primitive track of Puerto Blanco Dr. Cultural history is traced through remote paths like the Milton Mine Trail and Baker-Milton Trail, which lead into the rugged backcountry, marking historical mineral exploration routes that predate the modern conservation status of the area.
