Red Canyon in Israel
October 07, 2016
Eilat Canyon in the Negev Desert of Israel is popularly called Red Canyon. It's part of the Nahal Shani riverbed (Shani in the Hebrew language is vermilion color). This superb little gorge took shape when cut by a stream exposing red, Nubian sandstone that rises some 100 ft (30 m) from the canyon floor. The source of the red color is primarily iron (Fe) oxides, although, other oxidized minerals are also present. The approach to the canyon is by a trail the beginning portion of which is bordered by steep walls of conglomerate (top photo). For scale purposes, the ladder hangs down about 13 ft (4 m).
