P. PEARSON 1952 35 slopes. Some nice rocks slope + yareta nearby. Set 5 trap traps and about 25 MS among rocks and across the sandy-gravelly valley. Ante put out about 40 ms then bunchgrass flora. No sun all day and little visibility. Jan 30 Sprinkle of hail on ground at dawn, temp. 32° at 6 a.m.... at 8 a.m., 36°, foggy. Ante got 3 Abodon ardenia, I got 1 twee, 1 alvconna, 2 Phyllotis durmini, + 2 "" . The twee is very big, fuller more robust than ardenia, possibly one of the big chilen species. One of the ardenias caught in afternoon. Drove back up to the huincos to look around. Some of the gravelly soil too stony for twees; that with right texture scarcely worth enough food (although occasional Motstrokes and bunchgrass). Ante put out 30 MS and 5 still traps in a great rocky talus with sparse bunch grass and crevic plants. Some droppings looking like muisca, alvconna, and Durumi (although little smelly sage). Had a total of about 2 hours of sun, near 10 a.m., then clouds, fog, + drizzle. Drove back to previous night's camp at 15,300 ft where I put out ~~ 7 still traps for more alvconna and about 25 MS among big rocks on slope under cliff. Here vegetation but numerous micro droppings and some smaller. Also made 2 fox sets to protect the alvconna traps. Drizzle + snow all afternoon & evening. Jan>1 Morning foggy, 36° at 6 a.m., 2" of snow on ground. More of my traps springing although many more or rat tracks around. Many looked like Alvconna traps. Ante's line upon the huincos caught 1 Phyllotis + 1 Abodon ardenia. She is
