The website also addresses how to survive an avalanche. Afterward, users can take a virtual backcountry tour and test their avalanche skills. Researchers can discover the past and present projects of a variety of scientists to develop avalanche technology for workers including the SnowMicroPen, which is a penetrometer for collecting detailed snow profile information.
