Amos Frumkin and Derek C. Ford, “Rapid Entrenchment of Stream Profiles in the Salt Caves of Mount Sedom, Israel,” Earth Surface Processes and Landforms 20 (1995), pp. 139–152. Evaluation of these levels must take into account the uplift rate of Mount Sedom. See Frumkin, “Uplift Rate Relative to Base Level of a Salt Diapir (Dead Sea, Israel), as Indicated by Cave Levels” in Salt Tectonics, ed. G. I. Alsop, Derek J. Blundell and Ian Davison, Geological Society Special Publication no. 100 (London: Geological Society, 1996), pp. 41–47.
