Annular Eclipse

10/14/2023 | Mastodon State Historic Site | Imperial, MO

Did you know that the United States will be experiencing an annular solar eclipse this fall? A solar eclipse occurs when the moon blocks light produced by the sun. During an annular solar eclipse, the moon is at or near its farthest distance from Earth. The result is that the sun appears to create a "ring of fire" around the moon. At Mastodon State Historic Site, the obscuration, or portion of the sun covered by the moon, will get to about 64%, with the maximum occurring at 11:57 a.m. In Missouri, the best spots to view the eclipse will be in the northwest and southwest parts of the state, not in the St. Louis region, where Mastodon is located. However, our site is still a great place to watch the sky change and learn about the eclipse!

Join us in celebrating the eclipse. From 9 a.m. to 1 p.m., interpreters will be stationed at an informational table with facts and activities relating to the eclipse. At 10 a.m., we will have a solar story time for children. All activities are FREE and will take place across from the playground in the picnic area, located at 1800 Seckman Road in Imperial. Registration is appreciated for the story time. To register, click here or call the site office at 636-464-2976.

For all activities and eclipse viewing, participants should wear eclipse glasses designed for solar viewing.

Event Time: 9 a.m. - 1 p.m.
