Ambos Nogales

They lie 60 miles directly south of Tucson, Arizona, divided by the Mexico–United States barrier.

Though divided by the border between their respective nation states, the two municipalities have historically shared a sense of community alluded to in their description as "Ambos Nogales," as well as other sayings and phrases alluding to this camaraderie.

Investigation of community, migration, immigration (both legal and illegal), drug trafficking, gang violence, and all of the activities associated with these has occurred at Ambos Nogales due to its unique identity and geographic position.

It was not until 1898 that a material division other than stone cairns and obelisks marked the division between the United States and Mexico, a line of telephone poles were installed along the border cut through Ambos Nogales and guard posts were implemented at the crossing gates between the two settlements.
