White-water rafting and other river trips are fun adventures. They can go very wrong when a boat tips or a sudden storm hits. This book teaches readers about the river environments they may encounter and how to deal with their potential dangers. Real survival stories of life-threatening situations make these dangers real to readers, while offering important information on how to find food, deal with injury, and more should a bad situation occur. Multiple-choice questions and their answers ask readers to use their critical-thinking skills about surviving in the river environment while full-color photographs show them the ecosystem up close.
