Harambe, AZ, population 2? I call shenanigans.

Just to be absolutely sure, I've consulted with a number of sources. According to USGS maps (Peppersauce Wash quadrangle) going back to 1948, nothing by that name was ever there. According to the Pinal County Assessor's office, it's part of Parcel 307-10-0020, which belongs to the Magma Copper Company and is uninhabited.

In 2016, the Isleta Pueblo purchased the Comanche Ranch property in western Valencia County and added it to their reservation. OSM should be updated to reflect this.
