Hankew, James 1976 Journal Southwestern Research Station, Chiracahua Mtns, Portal, Arizona, 27 July 6 Aug (cont'd) We took the main toll road to Mexico City and (cont'd) another toll road, Mex 95D, S to Chignola and then Mex 95 to Chilpancingo. One can easily see how there can be a different Thorius in western Guerrero as the mtms on either side of Hwy 95 are separated by land w/ elevations never, if at all, exceeding 5000' elevation with quite mesic xeric vegetation of scrubby oak, arganize cactus and chaparral shrubs. Presumably the high mountains to the N are isolated as well, as Thorius has never been taken there. Upon arriving in Chilpancingo we checked at the Motel San Antonio for Ted Rozenfuss who is supposed to meet us on 30 July and he was not there. 28-29 July: Doug and I took a two-day sightseeing trip to the Acapulco area while waiting for Ted to show. The road S of Chilpancingo reaches ~4500 elevation before beginning a steady drop to the Pacific Coast. The scrubby pine forest is present on the S slope of the rise just S of Chilpancingo but seems too dry for Thorius and too. We stayed overnight at the Acapulco Trailer Park in Pie de la Cresta just outside of Acapulco. Returning to Guerrero on 29 July
