Fig. 3. Map of the Coahuila, Mexico, study region. Sampling sites are indicated by different symbols: red circle, Calaveras valley; star, CCB; square, Hundido valley; diamond, Rosario Mine. At the top and sides of the figure are photographs of habitats at each locality: new alfalfa field in Calaveras valley (1) ; El Mojarral headspring in the CCB (2) (photograph by Paolo Petrignani, La Venta Exploring Team; www.laventa.it); intermediate lagoon along a flow path from one of the CCB’s surface springs (3); desiccation pond in the flats of the CCB (4); native vegetation in El Hundido valley with an alfalfa field in the background (5) (photograph by Dean Hendrickson, University of Texas); and subsurface sampling site in the El Rosario mine (6) (photograph by Paolo Petrignani, La Venta Exploring Team). Major mountain ranges are also shown: La Fragua Mountains (a), San Marcos Mountains (b), Sierra la Purisima (c), Sierra el Granizo (d), and Sierra de Australia (the "Island of Coahuila") (e). Recent magma outcrops in the vicinity of the CCB are indicated by a red "blast" symbol and identified as: El Jabali valley (f) (J.M.R.-M., personal observation), San Marcos valley (g), and Calaveras outcrop (h). The red and black lines indicate major active faults, and the blue line delineates a hypothetical boundary for the hydrological system.
