12The Sierra de El Abra at QuinteroNovember 24-27, 1975Neil Montgomery, John ParkerJohn and I caught a bus down from the border aDd arrived at Quinteroearly on the 24th. We shifted loads of over 100 pounds each up the mountainpreparing for a seige on this littl; visited but promising part of the Sierrade El Abra. Leaving our gear at a radio relay station on top of the range,we began to explore the area to the west. Here we found many undistincttracks, some of them made by wood cutters from the village. Two leads werelocated during the day -- a pit about 30m deep dropping into a large passageand nearby the 40X7OmX30m deep collapse entrance to Cueva de las Colemenas,a cave visited several years ago by Bill Russell, but not fully explored.A major problem appeared during the day -- the area was crawling withticks. We each received several hundred bites and for night-time securityslept on the flat concrete roof of the radio relay station.On the 25th we relocated the 30m pit and descended it. To our dismaythe large passage below wuickly brought us to the·Colemenas entrance. Cuevade las Colemenas consists of one large chamber entered by several pits. Onlythe 40 X 70m collapse pit permits entry without rope. There is only onesignificant passage leading from the chamber. Tbis goes north 100m to wherea crawl leads to a deep, 3m diameter pit. The cave is well known to thelocal people, who· have exploited it for phosphate rich earth. In theirdiggings they opened up the northern end of the 100m long passage, revealingthe top of the deep shaft. We descended the shaft, a drop of 100m donein two pitches. At the bottom was the signature "German" which was a littlemystifying. There are no records of cavers having bottomed it.Next day we surveyed the cave (see map) and walked down to Quinterofor water. We were becoming dispirited from the tick bites, receiving manynew ones each day.New territory for the 27th: We followed a track north one kilOmeteruntil it faded and cut for another 600m to an "intermittent lake" shownon the Quintero topo map. These lakes are often pits. Colmenas is markedas one. The "lake" was not a pit (or a lake for that matter) but we didpick up a ~ood track there. This was followed one kilometer north to asmall settlement in a valley in the range top. The track continued northbeyond the settlement past numerous small pits and dolinas as it climbedout of the valley. Two of the pits required rope (30m) and we weren'tcarrying any. They did not look promising however being narrow and vadose.Nearly all of the important caves of the Sierra de EI Abra are remnantsof large phreatic systems. Still, a search of this immediate area may producesomething.The track faded one kilometer from the settlement and we followedsmall disconnected clearings for another km to an area containing four"lakes," directly above El Nacimiento (the Rio Mante source). We foundnothing here and attempted to drop down to the spring whose clear bluewater was driVing us mad, for it was a very hot day. We were stopped bycliffs 200m above it and headed back to the settlement and down hill fromthere to have that long awaited swim.That night we decided we were tired of being tick meat and left nextmorning. We had not covered much of the area.
