Abstract
The development of performance evaluation in sandstone climbing is linked to the development of climbing on sandstone rocks in the Czech Cretaceous basin and in the German Saxony. This paper describes the development of climbing performance on the Czech sandstone in the context of the given socio-economic situation and the influence of the Sudetenland German climbers.
It provides a short overview of the rules of sandstone climbing that were set at the beginning of the 20th century and are applied with certain modifications until today. This paper follows the development of performance evaluation in several different sandstone areas, pinpoints the milestones of sandstone climbing and explains the performance stagnation in sandstone climbing in the postwar period and further until 1990.
It compares the performance evaluation on different kinds of stone taking into consideration the local particularities of the evaluation and draws the attention to its high subjectivity of the evaluation.
