Several items of historical significance have been found in a cave in the Judean Desert. The most incredible find was a 2,000-year-old biblical scroll which makes it the first time that such an item has been found since the discovery of the Dead Sea Scrolls in the 1940s and 1950s. The Israel Antiquities Authority (IAA) and the Archaeology Department of the Civil Administration conducted several very difficult operations to explore all the caves in the area, although only about 80 kilometers (50 miles) of caves have been surveyed so far during their operation and around half of it still hasn’t been touched.
