James A. Sauer, former curator of the Harvard Semitic Museum, made an argument from geology and history that Pishon referred to what is now the Wadi Bisha, a dry channel which begins in the Hijaz Mountains, near Medina, to run northeast to Kuwait. With the aid of satellite photos, Farouk El-Baz of Boston University traced the dry channel from Kuwait up the Wadi Al-Batin and the Wadi al-Rummah system, originating near Medina.
