Exploration of ancient sites began in 1861, but only 7% of the area has undergone serious archaeological excavation. Some 1,500 ancient sites are located in a 1,200-square-kilometer (460 sq mi) area. In contrast to the gaps found in settlement periods in the neighbouring Negev Highlands and Sinai, these sites show continuous settlement for the past 10,000 years.[citation needed]
