Snow angel

[james.callan at COMCAST.NET]

Turns out "snow angel" isn't in the OED, dictionary.com or m-w.com. It also turns out that "snow angel" refers to things -- like crafts -- other than the pattern you make in the snow when you lie on your back and wave your extended arms and legs.

Is this a regionalism? (I grew up in Wisconsin.) How old is the term? Are there other words for the snow game?
