Murray 1948 66 Journal May 16 Triunfo, 1700 feet, Baja California built place, boasting almost all brick or stone buildings and many improvements including water pipes and pavement- all developed by the company which operated the mine here. However the company went broke, and the town collapsed. Now many of the brick buildings are in various stages of ruin. In one such compound mostly fallen down we found a second story room intact with all but one wall. The walls were plaster and the roof wood, supported by wooden beams a number of which were double. Between these were cracks of 1/2 to 3/4 inch wide containing bats in great numbers. Our total catch was 92 Tadarida mexicana and 2 Myotis velifer, and also 3 Eptesicus fuscus which appeared from somewhere below. Also looked in a long mine shaft but found no bats. We camped a short distance from town on the road to San Antonio, under a mesquite tree and in an arroyo. All around are rolling hills of rocky soil and covered with a dry leafless growth of lumbroi, copal and other thorny bushes.
