summer, but snow in summer. Winter temps get down to -10C. He hunts lots of medium-sized armadillos. People from Matorque come and hunt many graceros in nearby hills. Water table is only a meter or two down, somewhat salty, a layer of salitre. Oil + gas wells and lots of drillship. He says there are abundant cool mines near both El Bosmedo and Molargio (up roads to the west, I think). One of them has a hotel up the same road, a man named Castano (near Molargio?) knows all about one of them. Left about 9:30, early lunch in Molargio, then south on Route 40. Man in Molargio says summer temps up to 30, winter down to -10C, but snow only about once a winter, and rain only a half-dozen times a year. Lots of alamo plantation which are said to motive to cutting size (for lumber) in 5 yrs. Camped 3 p.m. in a zedo canyon about 1 mile west of the Rio Grande about 10 km by road south of Cordas Blancas and 60 km S Molargio. Root-ridden habitat of eshedra, thorn bushel, occasional bunch grass, lots of stoney-gravelly soil visible (maybe 30% plant cover). A narrow quebrado next to camp, dark cliffs across the Rio Grande and on this side also about 1 mi. south of camp. Set about 35 museum species in a rocky cliffy outcrop and among eshedra + thornbush, also a lot not across our side gully (with stream) and across a big galvanized culvert under the road. Dinta also set traps Oct.25 Night clear, 34°. Nothing in nets or traps. Very few birds of any sort, no chimangos (sterility index). Left about 9:30 and drove south on Route 40. Junch at Barruecas, through Clos Madal. All senin-ark, sagebrush, occasional striped Toxteles, usually with Poplar tree. Saw one troop of bees, nocturnous, fides or quiver
