RB022 Glacier Cave-In

A group of scientists is studying a cave exposed by the melting of the Big Slide Glacier several miles north of Knotty Pine. The scientists find what they believe are the bones of a prehistoric caveman and other ancient artifacts. The movements of the glacier create an earthquake and a big rock slide. One of the lead scientists, Dr. Swift, is trapped under part of the avalanche. Dr. Swift's leg is crushed under a huge rock and may have to be amputated to save his life. The team of scientists has no way to contact the outside world. One scientist tries to climb down to find help. Bill and the boys decide to climb up to Big Slide and check on the scientists. Will Bill get to the scientists in time? Will he be able to save Dr. Swift's life?
