William Francis Lynch,
Narrative Of The United States Expedition To The River Jordan And The Dead Sea…
(1849)
“ At nine o’clock, when the heat of the sun began to be oppressive, they reached a low cave in the southern face of the mountain, over Wady Seyal, — a deep ravine, which separates the cliff from the main ridge on the north. Here they dismounted, as it was impossible to proceed farther on horseback. Hence, sometimes upon their hands and knees, they clambered up the steep and rugged cliff, its perpendicular side pierced with apertures, like the Rock of Gibraltar. ”
