5.6 Transport: bone skates and a sledge runner
Bone skates were made from horse radii and metacarpi and a cattle radius. A sledge runner was made out of a horse metatarsus (table 3; fig. 32). That these objects were used on a completely flat and hard surface, i.e. ice, is proven by the flat dorsal side of the bones, which makes straight, sharp edges with the lateral and medial sides of the bones (Becker 1990).
To skate using bone skates, a person would have had to use a stick to push oneself forward and feet were not lifted from the ice during skating (Clason 1980; Becker 1990). This explains why several bone skates found at the site lack holes for ropes to attach the skates to the feet. Ten bone points, made out of cattle, horse and sheep long bones, are identified as the tips of skating sticks (fig. 33) (compare Lauwerier 1995, 203-204; Lauwerier & Van Heeringen 1995, 6-7).
