Is that lake safe to land on?

Landing on a frozen lake can be challenging, even for the best aviators. That’s why the U.S. Forest Service and Interior Department has summarized lessons learned about landing on a frozen lake from a recent incident. Last December, a Super Cub with tundra tires landed on a frozen lake in Alaska and fell through the ice. Everyone onboard was rescued, but the summary notes certain things indicated that ice may not be able to support an aircraft, including pressure ridges, frozen bubbles, cracks, overflow and dark spots.
