“The section given by Lynch indicates that the place of greatest depth lies much nearer the Moabite than the Judæan shore, and the descent from the base of the Moabite escarpment below Jebel Attarus and between the outlets of the Wâdies Mojeb and Zerka Maïn, is very steep indeed. The deepest part of the trough seems to lie in a direction running north and south, at a distance of about 2 miles from the eastern bank; and while the ascent towards this bank is rapid, that towards the Judæan shore on the west is comparatively gentle. The line of this deep trough seems exactly to coincide with that of the great Jordan Valley fault. From the bottom of the deeper part, the sounding line brought up specimens of crystals of salt (sodium-chloride), and it can scarcely be doubted that a bed of this mineral, together with gypsum, is in course of formation over the central portions of the Dead Sea.” [_Authorities and Sources_:--“Memoirs of the Survey: Geology”, Dr E.

There are old maps which represent these cities as situated at the bottom of the Dead Sea waters, and yet enveloped in flames! Popular ignorance imagines that the bitumen which rises to the surface of the waters is a relic of the agency which effected the destruction. And until recently even the best scholars supposed the cities to lie beneath the shallow part of the sea, south of the Lisan peninsula. All such theories are disproved by the geological investigation, which shows that the Dead Sea is much older than any date which can be assigned to the destruction of the cities, and that the surface of the water has been constantly diminishing in area and sinking to lower levels.
