Then, abruptly, Balto stopped. Kaasen shouted at him
to go on, but the dog would not move. Kaasen ran
forward to see what was wrong. Balto was standing in
several inches of icy water. They were on the bank of
the Topkop River, and the ice below was beginning to
give way. Had they continued, the team and sled would
have pitched forward into the river. Balto knew what he
was doing. As soon as Kaasen dried the dog's feet,
Balto made a turn and led the team around the river
and back to the trail.
