JPMyers 1973 Journal 38 Pucial Route #307 between [illegible] and Antiguo Quilmes, Pucia de Tucuman, Argentina 5 October Left and drove south from Tucuman on Nat. Route #38 to [illegible] and turned west there on Pucial Route 307. We passed through [illegible] at approximately 0930. Weather was raining (the first of the season according to CC/frag), cool (in the 50's) with a wind blowing strongly to the west. Elevation at Montewo is 11200'. We made little systematic attempt to identify birds as we saw them, but did make an effort to find shorebirds. The road follows a river up the mountain to a pass at 9900' called Abra de Juferrillillo. On the opposite slope it follows a stream down to a large valley, the bottom of which is 6000' and which follows the Rio Santa Maria. Going up from [illegible] the first 20 km is flat, green passing through sugar cane fields. Then there is an abrupt change to mountain road (road surface good in rain, though) and a dense subtropical rainforest of bamboo, bromeliads, very large trees, and [illegible] fuschia. Orog told us to expect forest ducks and Cinclus schulzii, but we did not see them. The vegetation changed little until ~3000', when the undergrowth began thinning out (changed little, that is, to an uncritical eye). Abruptly at 6000' the road breaks out into a very large valley over 13 km long and not quite as wide. At this point the vegetation becomes pampa-type steppe-like in nature. The weather broke here too, with the clouds (which had been at road level on the way up) lifting and clearing. We stopped to eat on a broad open field about 6 km from the opening of the valley. Here the ground vegetation was a very closely cropped grass; much loose shit all around. A pair of Andean hupings were on the
