The descriptions that follow are based on the experience of each of the expeditions that participated in the Banco de Chile’s "Summiit Box" project. It is recommended to take them as a guide to be adapted to your level of acclimatisation and physical preparation.

In the same way, the given waypoints are information taken by each of these expeditions and therefore are referential and not official information. For this book, all the information was transformed to DATUM WGS 84.

The suggested climbing seasons are only a reference, subjective to the climactic conditions of each year and the personal taste of the climber.

The height given at the start of each chapter is the official altitude according to IGM, as is the geographical position and the map reference (scale 1:50,000).

As there are no 1:50,000 maps for the mountains of the Tarapacá Region that this book describes, the references are from 1:250,000 maps.
