Hauken, James 1976 Journal en route to SF from LA, California, U.S.A. 14-18 February usually involved driving during night or early morning along the central western side of the mountains and making successive stops to the high elevation pine or pine-oak forests via usually good logging roads to small pueblos to these areas. The weather was generally good with sunny skies and warm temps during the days. Although these areas were generally dry, moist habitat habitat for Thorius could generally be readily found in the form of N or NE-facing wooded slopes with abundant cover. Thorius were not overly abundant, but a good series was usually detained with a little work. Other salamander species, however, were conspicuously absent. In this manner were the following areas worked: Cuaixmoloyas - 14 Feb; Santa Reyes Papalo - 15 Feb; Tepoztlan - 16 Feb. On 17 Feb we headed NE for Thorius locality at Las Vigas, stopping en route at localities in Fortin and Xalapa (see below). On 18 Feb we left Las Vigas and returned to Mexico City, making one unsuccessful visit to our first locality in the pine forest W of Rio Frio, Edo. Mexico to find additional Thorius. Each day is briefly treated separately below;
