Nestled in the rough mountainous country west of the cities of Nogales, Arizona, and Nogales, Mexico, Boundary Monument 127 is a significant geographic turning point for the U.S.-Mexican border - and is located on the WRONG spot!
Read the full story of this 170-year-old incorrect border marking HERE after viewing these images from the historic Arizona-Sonora boundary angle along the U.S.-Mexican border west of Nogales. Please leave a comment at the end of your journey here.
“Boundary Angle Canyon” is a mostly remote area, but U.S. border wall system construction in summer and fall 2020 made this corner of the Pajarito Mountains a busy crossroads.
The mountainside northwest of Boundary Monument 127 has been destroyed to serve as a batch plant for preparing border wall concrete. By November 2020 Boundary Monument 128 (on the cut-out mountain to the left) became the base camp for construction work heading deeper into the rugged Pajarito Mountains.
Though located on the wrong spot for 170 years, Boundary Monument 127 still marks the angle along the Arizona-Sonora border between Nogales and the Colorado River. Will this neglected and endangered monument – which includes a handwritten inscription from the 1855 U.S. Boundary Commission – survive amid this altered landscape?
