GULLY SINK 1 (aa -)

Herbert Daniel Gebauer - 06/01/2018

An unspecified cave entrance (unidentified shape, unidentified dimensions, unidentified orientation, unidentified characteristics), which appears to represent a seasonal sink and pothole, was understood to be one of two seasonal stream sinks (Brooks 2009.06.06 Mss: Gully Sink 1 and 2) which occupy one and the same space. ETYMOLOGY: No locally known cave name has been identified for what Henry Rockcliff identified on 19th February 2009 as a sink in a gully without identified name. Within a few months, Simon J. Brooks nicknamed Henry Rockcliff's nameless sink on 6th June 2009 Gully Sink 1 (Brooks 2009.06.06 Mss: Gully Sink 1 and 2): Made up name as caves situated in a gully (note 1). SITUATION 1: Not only in an inexplicable location falling on the Tangnub quadrangle (N25°18': E092°30' to N25°19': E092°31') and exactly the same spot as the second –>Gully Sink 2 (Brooks 2009.06.06 Mss: Gully Sink 1 and 2) but also without identified spatial relation to the other known cave entraces in the –>Um Muju area (note 2). APPROACH (modified after Brooks 2009.06.06 Mss: Gully Sink 1 and 2): From Tangnub village, follow a 4WD track descending west to paddy fields. Leave the track at a turn (N25°17'50.1”: E092°30'56.5”) to follow an allegedly nameless and obvious gully (unidentified) down onto the limestone. Some 20 or 30 m after reaching the limestone, there are two sinks, the first of which (1) is the deepest & more open. Both sinks have loose rock in vicinity of entrance. CAVE DESCRIPTION 1: One of altogether … nine new caves, all of them with vertical entrances under the big broken boulders. Most of them are drafting [sic! more likely: draughting] and oulook [sic!] of all the caves are good (Brooks, S J et al. 2009 Mss -Diary 2009.doc- Thursday 19th February). CAVE DESCRIPTION 2: Pitch 20 m plus deep heading under stream (Brooks 2009.06.06 Mss: Gully Sink 1 and 2). PROSPECTS: Good (Brooks 2009.06.06 Mss: Gully Sink 1 and 2). CAVE CLIMATE: On the one-hand side, tere is draught present (Brooks 2009.06.06 Mss -Gully Sink 1 and 2- cave description) and on the other hand there is draught / air movement present in sink 1 (Brooks 2009.06.06 Mss -Gully Sink 1 and 2- outlook).ere is draught present (Brooks 2009.06.06 Mss -Gully Sink 1 and 2- cave description) and on the other hand there is draught / air movement present in sink 1 (Brooks 2009.06.06 Mss -Gully Sink 1 and 2- outlook).
