The strait was bridged by land until about 14,000 years before present when sea level rose to about 75 meters below present sea level, ^[1] unlike Lombok Strait and Alor Strait which continued to be water gaps even during the Last Glacial Maximum, at each end of a 400-mile-long island including present-day Lombok, Sumbawa, Komodo, Flores, Solor, Adonara, and Lembata.
