Weather predicting tortoise wakes from winter nap

While Pennsylvania has its weather predicting groundhog, Max is the unofficial seasonal prognosticator in the Nevada desert.

He's a tortoise at the Red Rock Canyon national recreation area near Las Vegas.

When Max emerges from his burrow it's springtime.

He's about a week later than usual this year.

Now, officials are going through thousands of guesses submitted by Las Vegas-area school kids.

The kid with the entry that comes closest to Max's actual end of hibernation will win a bunch of prizes and a class trip and pizza party at Red Rock Canyon.
