[34] The record is copied literally without regard to the absurdity of the second and third decimal places.
[35] In the Eastern Cordillera, however, snowstorms may be more serious. Prior to the construction of the Urubamba Valley Road by the Peruvian government the three main routes to the Santa Ana portion of the valley proceeded via the passes of Salcantay, Panticalla, and Yanahuara respectively. Frequently all are completely snow-blocked and fatalities are by no means unknown. In 1864 for instance nine persons succumbed on the Yanahuara pass (Raimondi, op. cit., p. 109).

[38] This figure is approximate: some days’ records were missing from the first three months of the year and the total was estimated on a proportional basis.
