Mont Blanc, the highest peak of the Alps is less than 20km away, and is visible in the background. Thank to the Alpine collision, this former sea floor was thrusted over gneiss and granite to make both geologists and mountaineer ...[Read More]

The Zin Valley takes its name from the River Zin, which is now a dry river except for a few days of the year when heavy rainfall can form dangerous flash floods. The River Zin originates from the Makhtesh Ramon (Crater Ramon), the biggest erosion crater in the world. It is located a ...[Read More]
