Mount Ebal (Arabic: جبل عيبال Jabal ‘Aybāl; Hebrew: הר עיבל Har ‘Eival) is one of the two mountains in the immediate vicinity of the Palestinian city of Nablus in the West Bank (biblical Shechem), and forms the northern side of the valley in which Nablus is situated, the southern side being formed by Mount Gerizim. The mountain is one of the highest peaks in the West Bank and rises to 3084 feet (940 meters) above sea level, some 194 feet (59 meters) higher than Mount Gerizim. Mount Ebal is approximately 6.5 square miles (18 square kilometers) in area, and is composed primarily of limestone. The slopes of the mountain contain several large caverns which were probably originally quarries, and at the base towards the north are several tombs.
From Bædeker: (1898) Route 22 page 257
The ascent of (1 hr.) Mount Ebal (3077 ft.; 1207 ft. above Nâbulus) is more fatiguing and less frequently undertaken than that of Mt. Gerizim; but the summit is higher, and the view still finer. The path winds up over terraces hedged with cactus. Near the top on the W. side stands a Muslim weli which attracts pilgrims and is said to contain the skull of John the Baptist. The highest part of the mountain is towards the W. side; on the summit are the ruins of El-Kal'a ('the fortress'), the walls of which are very thick; a little farther E. are other ruins called Khirbet Kunciseh ('little church'). The View extends over the mountain-chain of Galilee, from Carmel across the plain of Jezreel to Gilboa; Mt. Tabor, Safed in the extreme distance near Hermon. the coast-plain to the W., and the distant mountains of the Hauran to the E. are all visible. — On a hill a little to the N. of Mt. Ebal is Tallûza, identified on rather insufficient grounds with Tirzah, which for a time was the capital of the northern kingdom (1 Kings xvi. 8, etc.).
From Murray: (page 343)
Mount Ebal lies on the N. side of the vale of Nâbulus, opposite Gerizim, and is nearly equal to it in altitude. Its sides are somewhat more rugged, and its general outline perhaps bolder than Gerizim. The ascent is not difficult, a goat-path leading up from the town past a little wely. On the summit is a broad stony platform, with a few unimportant ruins; but no traces of what might probably be the altar built by Joshua on which the Law was inscribed. (Josh. viii. 30-35.) The view is wide and interesting, resembling that from Gerizim. About 2m. to the N.E. we see the large village of Tullûzah, situated on high ground, and surrounded by extensive olive-groves. This is probably the ancient Tirzah, which for a time enjoyed conjointly with Shechem the honours of a capital. (1 Kings xiv. 17; xv, 21; xvi. 8-24.)
