Description
A choked »swallet« (note 1) or sinkhole gives access to an estimated 5 m long cave passage leading to an estimated 10 m deep boulder pot full of attractive harvestmen (Opiliones). SITUATION: In what had been in February 1999 a "ram" (jungle cleared for cultivation) about 150 m south of the cave entrance to the Thlu –>Nara 1 (Antony 'Tony' Boycott & Anthony R. 'Tony' Jarratt 1999.02.99 personal communication).
NOTE 1: Swallet is a term used mainly in the Mendip Hills (United Kingdom of Great Britain and the rest), and derived from swallow hole (synonym for the US American English sinkhole): A point where all or part of a surface stream disappears underground. Some definitions restrict its use to sink points in closed depressions (any karst hollow with internal drainage) or dolines: Circular closed depression, either saucer-shaped, conical or in some cases cylindrical. The name originates from the Slovene term for a valley, where in the Classical Karst there are no true valleys but only closed basins. Dolines may form by dissolution, collapse, or a combination of these, keyed to a central sinkhole or intercepted cave passage. They are ubiquitous features of limestone karst, but can form in or above any soluble rock; subsidence dolines are developed in insoluble sediment leached or collapsed into an underlying cavernous limestone (LOWE & WALTHAM 1995: Dictionary of karst and caves.- ISBN 0-900265-9-1 pages 13, 35).
