Just over an hour before 11:33 a.m. MDT, the Salt Lake Valley sky will start to transition from a typical late-morning hue to dusk as the moon makes it way across the sun, gradually blotting out sunlight.
Monday’s eclipse is the first in 99 years to traverse the U.S. coast to coast, with the path of totality stretching from Salem, Oregon, through nearby Idaho and Wyoming, and then south and eastward across the rest of the country. A partial eclipse will be visible on most of the North American continent.
Build up for the once-in-a-generation astronomical event has been months in the making.
