Naure Reserves in the Negev Desert
A maktesh is a geological landform considered unique to the Negev desert of Israel.
The dynamic earth has formed almost unique geological landforms in the Negev desert. Initially, a layered sequence of hard Iimestone and dolomite rocks was deposited over softer sandstone sediments. The sequence was folded into asymmetric folds, producing four parallel, northeast - southwest, topographical ridges, An erosion surface removed the hard limestone and dolomite rocks of the fold's crest, exposing the underlying friable sandstone, which was eroded, forming a deep transverse valley. The creeks drain into the Dead Sea - Arava valley, through a single outlet, incised into the southeastern flank. The closed valleys are surrounded by steep cliffs, 200-400 m high. This type of breached valley or erosion crater is known as a "makhtesh". A makhtesh is a "geological window" through which the ancient strata are revealed. A makhtesh contains a variety of different colored rocks, and diverse "fauna and flora". The area of each makhtesh has been declared a nature reserve, providing an ideal location for recreation and leisure with trails for hiking, cycling and jeep tours.
