Eclipse over Wyoming: As found from the NASA interactive eclipse map, the centerline of the Moon’s shadow crosses into Wyoming five miles west of housetop Mountain, just north of the Teton Pass Highway at 11:34:27 AM Mountain Daylight Time (17:34:27 Universal Time). At the border, totality lasts 2 minutes, 19 seconds and the path of totality is 66 miles wide.
At Caspar, Wyoming, totality begins at 11:42:40 AM, and lasts for 2:26. The lunar umbra passes over 366 miles of the state of Wyoming in the span of 14 minutes, 58 seconds, at an average speed of 1759 miles per hour, or 2.31 times the speed of sound.
The Moon’s shadow along the centerline departs from the state just east of Route 47 and crosses completely into Nebraska at 11:49:25 AM MDT (17:49:25 UT). At the eastern border, the duration of totality is 2 minutes, 29 seconds and the path of totality is 70 miles wide.
NOTE: Duration of totality is longest along the centerline. Duration of totality approaches ZERO near the edges of the path of totality. Please consult the NASA interactive eclipse map for precise times and durations of totality at each specific location in the state, along with locals times for the beginning and ending of the partial eclipse phases.
Lodging: As with all locations along the path, hotel reservations will fill up well in advance. Plan instead to tent camp or rent an RV. While there are many commercial and public campgrounds, primitive camping is inexpensive in the National Parks and free in the National Forests.
Traffic Concerns: In the event of any last-minute, impromptu eclipse day trippers, I-25 might experience a traffic jam in the event that great numbers of people from the big cities in Colorado head north through Cheyenne toward the path of totality.
Weather: According to the Eclipsophile site, based on meteorological averages, Wyoming has excellent weather prospects for Eclipse Day. Many seasoned, veteran “eclipse chasers” have expressed their intentions of viewing the eclipse from Wyoming.
Planning Your Wyoming Eclipse Vacation: Please read the resources on our Be Prepared! page for finding opportunities for overnight lodging at your Wyoming eclipse viewing destination. There are many outdoor attractions in Wyoming, from Yellowstone National Park, the Grand Tetons, and Devil’s Tower. The path of totality passes over considerable open country, so there is ample space for accommodating prepared eclipse chasers. Explore the Wyoming Tourism page for more information.
