Spirit Mound Historic Prairie is hosting a Monarch Migration walk in the park Sept. 10 at 6:30 p.m.
In early fall, Monarch butterflies make their journey to Mexico. Since the migration route and distance varies from butterfly to butterfly, the University of Kansas developed a research project to help monitor their flight.
"Everyone is welcome to help with the project or to just learn about the travels of monarchs," said Jody Moats, S.D. state park naturalist. "Participants will walk the trail to the summit of Spirit Mound, while catching and tagging monarch butterflies."
If you have questions or would like to pre-register, call (605) 232-0873. Spirit Mound is located 5 miles north of Vermillion on Hwy 19.
