Our last siyur of the z’man took place in Wadi Kelt along the beautiful Derech Allon just past Ma’aleh Adumim. We had a great time walking along the water and getting wet (some more than others :) in the refreshing springs. We also witnessed the fascinating spring at Ein Fawwar where water, every 20 minutes, flows in and out seemingly controlled by a computer but, in realty, by collections of water that collect through the surrounding limestone into a karst cave (i.e. caves formed by the dissolution of limestone).
