text: Lado was the largest town in the enclave, while Yei, a fortified military station on the Yei River, was considered the second most important town. The northernmost post was Kiro, on the west bank of the Nile nineteen kilometres above the British post at Mongalla, while Dufile, Ismailia and Wadelai were other settlements. English traveler Edward Fothergill visited the Sudan around 1901, basing himself at Mongalla between Lado to the south and Kiro to the north, but on the east shore of the river. By his account "Kiro, the most northern station of the Congo on the Nile, is very pretty and clean. Lado, the second station, is prettier still". However, he said that although the buildings were well made, they were too closely crowded together.
  While a large percentage of its population were Indigenous inhabitants, many Bari left the enclave, escaping Congo Free State rule, and settled on the eastern (Sudanese) shore of the Nile.
  The enclave was an area of seismological activity, particularly around Rejaf (which means "earthquake" in Arabic). A fault line runs as a notable escarpment west of Rejaf south to Lake Albert, and while no major tremors occurred during the existence of the Lado Enclave, there was a noticeable earthquake in the region, centered on Rejaf, on 21 May 1914, which destroyed or damaged most of the buildings in the town.
  Fauna and flora
  The enclave was well known for its enormous herds of elephants which drew big-game hunters from around the world. Starting about six weeks after Leopold's death in December 1909, from the years 1910 to 1912, hunters arrived in great numbers and shot thousands of elephants before Sudanese officials were able to take control of the area. One of the most prolific was the Scottish adventurer W. D. M. Bell.
  Hippopotami were described as having been "extremely numerous and particularly obtrusive" in the enclave but their presence had dropped to almost zero during the enclave's existence.
