On Monday, the United States becomes ground zero for a full solar eclipse. For many, it’s a once-in-a-lifetime event — it is the first time in 99 years that a total eclipse has traversed the U.S. coast to coast.

Here in Aspen, the sun will be 92 percent occluded at the peak of the eclipse; the eclipse will begin at 10:20 a.m., peak at 11:43 a.m., and end at 1:11 p.m.

It will be celebrated in countless ways; here are a few local happenings:
