Hikers Discover Igloo in Lower Yosemite. The Daily Fitchett.
While hiking in Lower Yosemite, we happened upon this igloo that someone had built. While we were goofing around in the igloo, another hiker who had witnessed its construction came up and told us a family of three - mom, dad, and son - had built it in less than two hours. This particular igloo was tall enough at the center that a short person like me can fully stand up, and it is relatively warm in there (i.e. 32 degrees Fahrenheit inside as opposed to 12 degrees - and dropping fast - outside).
