The summit of Masada sits 59 m above sea level and about 470 m above the level of the Dead Sea. The mountain itself is 610 m long, 200 m wide, 1330 m in circumference, and encompasses 23 acres. The "Snake Path" climbs 280 m in elevation. From the west, the difference in height is 70 m.
Investigation of tamarisk branches in the Roman siege ramp result in the conclusion that fifty percent more rain flowed through the wadis into the Dead Sea when Flavius Silva built the siege ramp.
A recent article suggests that this ramp was mostly natural and only the top 26 feet was added by the Romans. Today a rope-way takes you to the top in a cosy airborne cabin.
