Ascender contains 94 original photographs taken in the southern winter of 2017. The images were composed during a 5-day trek through the Salkantay Pass in the Peruvian Andes. Each photograph is presented in chronological order and marked by the altitude at which it was captured. This printed version contains an additional 34 pages that were not included in the original digital version (bonus material!).
