When everyone else looks at this photo they see a desert environment with sand dunes. I see an area that was once submerged under seawater as evidenced by a system of raised shorelines.

This is an oblique image from space of the Sinai Peninsula. Although difficult to discern because of scale there is a suite of raised shorelines traceable through the northern Sinai. They tilt up to the north in the direction of Israel (some of these same levels occupied the Dead Sea valley). The present shoreline of the Red Sea and the associated Gulfs of Aqaba and Suez truncates some of these tilted shorelines. The research literature indicates that glaciers did not overrun this area. If that is the case, the tilt of the shorelines or the truncation events cannot be attributed to isostatic rebound following the withdrawal of ice

This image of Egypt and the Red Sea shows high altitude perched shorelines encircling former islands that are now uplands standing above the old sea bed. The area covered by this image was not at this geographic position when the highest shorelines were formed. The shorelines are obscured somewhat by eolian sands. Shorelines in the lower elevations can be seen diverging from, as well as truncating, older, higher ones. These lower levels trace a narrowing channel that once linked the basins now occupied by the Mediterranean and Red Seas. At various times in Holocene history (i.e., the past 10000 years) the Red Sea basin has alternatively been an embayment of the Atlantic and Pacific Oceans. Today, it is an embayment of the Pacific Ocean. The alternating emergence and submergence of the Red Sea basin and the Nile River valley has instigated enormous changes in the path of human history in these areas (e.g., migrations up and down the Nile; the sudden disappearance and emergence of cultures, etc.).
