South Sinai’s mountains form an ancient landscape that contains some of the world’s oldest rocks dating back to 1,100 million years. Most of the rocks you see are granitic; the grey granites are up to 850 million years old while the more frequent rose granites are younger at about 650 million years.
The varied and mixed colours of the rocks hint at the landscape’s complex and often violent geological evolution. Relatively young rocks can be found next to ancient rock formations. Gebel Katrin is the highest mountain in Egypt, reaching a height of 2642 meters.
Over millions of years forces inside the earth have caused volcanic eruptions. You can see dark veins, or dykes, cutting across mountains-- sometimes running for several kilometers. .
