Ronto, Dean 2012 Journal San Antonio de las Alazanas, Coahuila, Mexico (cont) Oct. 13 ... turned off at Santiago and took a winding, narrow road to Laguna de Olinda, N.L. This turned out to be a big mistake; would have been much faster to take highway to Saltillo. Road passed through pine, fir, and broadleaf forest that looked very good for salamanders. Continued through Coahuila, which was somewhat drier but still looked more like salamander habitat to me than the P. galaxiae sites at Miguiliana and Puerto de Conguillas; definitely worth a look in the future. Arrived in San Antonio de las Alazanas just after dark, too late to look. Everything was wet from a heavy rain that day. This morning we drove 10.3 km E from the center of town and searched from 09:05-10:45 at Los Olmados calvas (25.22139°N, 100.39462°W [+/-10m], 2729m elev.). Mix of pine and fir forest w/ patches of aspen - looks like spectacular salamander habitat. Looked under rocks and in some good logs but found nothing. Forest extends about halfway up slope on S side of valley; N side is scattered pines w/ agave and shrubs. Went back 2.1km towards San Antonio and searched in more pine-fir forest and in a roadbank from 11:00-11:30 but found nothing. Was surprised we didn't get any C. nigrescens, given how abundant they were on the nearby Cord Potosi. All this really is their range limit; might have something to do with it. Drove back to DF, made it in just over 8 hours. Stayed w/ Gabriela, who generously took me in.
