In this paper, detailed results of 277 tests at three sites in Austria and 34 tests at the site in Canada are described. The tests involved a total of 311 boulders ranging from 0.18 to 1.8 m in diameter and from 0.009 to 8.1 Mg in mass. The geology of the different sites included strong rock belonging to igneous, metamorphic and volcanic types.
