Description

Michael Laumanns - 29/11/2015

(West province, Virunga mountains) Co-ordinates: S 01"30'02.0”; E 029°33'12.2”. Alt. ca. 2,215 m. Explored by the 2004 international expedition to NW Rwanda. Lava tube cave with a single roof collapse doline that serves as entrance. The NW section of the cave is narrow and soon ends with an entrance closed by rocks that is used as a toilet. The SE Section of the cave is spacious, has a clear inclination, and carries a small water stream during the wet season. A boulder choke towards the SE can be by-passed but the cave soon terminates in a narrow crawl that was not pushed seriously and has a strong air current. Thus, the cave could be extended in the future. Ubuvumo Nyiragihima has some loops and parallel passages, all of which re-join the main lava tube. Some remains of a hideout were found in the cave that has no human bones. Survey and description according to Laumanns et al. (2005, 2007).

Histoire

Une expédition de trois semaines a été réalisée en février 2007 par le Néerlandais Jan Paul van der Pas et Michael Laummans, dans la région de la chaîne volcanique Virunga au nord-ouest du Rwanda (Afrique centrale), afin de lever les derniers points d’interrogation restants.
