Two arizona teens stranded on cracking ice for hours, until they were saved by a quick-thinking friend and fast-working first responders. Abc's cecilia vega has the story. Reporter: The frozen lake was cracking by the minute. All the two stranded boys could cling to but a dying tree and short branches. And that's where they waited to be rescued for more than four hours. We weren't sure what was going to happen. If we were going to fall all the way and have hyperthermia and maybe die. Reporter: It started off as a fun walk across the lake near their arizona home. It looked pretty frozen. Reporter: But when 14-year-old christian van aller and alex orton stepped on the ice, they heard cracking and rushed to the tree. It started really cracking maybe 20 feet back. And so, we were trying to hurry and get across. That's when it really sunk in and broke. Reporter: Each had a shoe stuck in the ice. They had to cover their freezing feet with their hats to stay warm. On shore, alex's brother called for help. But the first call wasn't to 911. It was to mom. I knew I was going to be in trouble when I got home. That was the main thing that was in my head. Reporter: As rescuers raced to bring the boys to safety, temperatures dropped as night fell. If they were in a different location and ice that thin, the outcome wouldn't have been so good. Reporter: They say they learned their lesson. We're not going to take away the cell phone. That's the only reason they got rescued. X-boxes maybe. Reporter: While they may be home safely, these boys are not quite out of the woods just yet.
