KHOREKOL

Herbert Daniel Gebauer - 06/01/2018

A tunnel cave (past one daylight window) connecting the downstream end of a valley in pinnacle karst to a resurgence at the rim of (the locally) shallow limestone outcrop. SITUATION: Below –>Matrongkol (Asakgre) and at the lower end of a valley (dry in February 2003) with sand in the riverbed. Compare: Bolchu Nabang. CAVE DESCRIPTION: An inspiring cave entrance (15 m wide, 3.5 m high) to a north-south running passage (7 m wide, 2.5 m high, 30 m long) leads to a collapse obstructed by boulders and driftwood. A squeeze leads to the top of a 2m-climb down into a dirty, shallow pool from where the north-south running passage continues below a daylight window (15 m above) to enter an Y-junction. Here, the NS-passage turns to the right, continuing all the way to the resurgence (185 m, inclined by -7°) as a NNE-SSW passage. Some 50 m from the Y-junction, the main passage splits into two parallel 20m-passages (the right / north-western one requires swimming but the left is dry). They unite ata cross-rift chamber, split again, and re-unite once more to continue from now onwards as a level passage to a daylight-lit collapse area at the rim of the limestone outcrop. CAVE POTENTIAL: An unsurveyed passage with considerable air draught (air current) entering at the Y-junction from the north-east. Some 250 or 300 m in a direct line approximately SSW, the –>Bolchu Nabang appears to represent a downstream continuation of Khorekol. POSITIONS (WGS84, H.D.
