With Christmas Eve already upon us, many parents and children might already be tracking Santa Claus and his team of nine reindeer as they travel around the world, delivering gifts along the way. So, when is Santa headed for Colorado?

For 70 years, the North American Aerospace Defense Command (NORAD) has made a holiday tradition of its Santa Tracker, which follows St. Nick across the globe.

This Christmas Eve, over 1,000 dedicated volunteers will staff the 1-877-HI- NORAD hotline from 4am to midnight Mountain Standard Time, ready to field calls from eager Santa-seekers.
