Mu Ngava

Mu Ngava, or Rennell, is a long raised coral island south of the Solomon Islands. Limestone cliffs fringe much of its coast, while Lake Tengano occupies the former lagoon at its eastern end. Together with nearby Bellona, it is a Polynesian outlier whose inhabitants speak a language related to those of islands farther east. Island traditions trace ancestors to Uvea and Futuna. Around 1801 Captain Butler named Rennell and Bellona during the voyage of the Walpole.
