Figs. 116-118—Temperature curves for locations in the Maritime Cordillera and its western valleys, October, 1911. For construction of curves see Figs. 109-113. [116] is for Camp 13 on the northern slope of the Maritime Cordillera (which here runs from east to west), October 13-15; [117] for Cotahuasi, October 26; [118] for Salamanca, October 31.

Abancay, 8,000 feet (2,440 m.), in one of the inter-Andean basins, is situated in the zone of marked seasonal precipitation. The single day’s record shows the characteristic effect of cloud reducing the maximum temperature of the day and maintaining the relative humidity.
Camp 13, 15,400 feet (4,720 m.), lies near the crest of the Maritime Cordillera a little south of Antabamba. Afternoon storms are one of its most significant features. Cotahuasi, 9,100 feet (2,775 m.) is near the head of a west-coast valley. Its low humidity is worthy of note. That for Salamanca, 12,700 feet (3,870 m.), is similar but not so marked.
