A particularly unique Boulder ritual is set to unfold once again Friday as the city marks Groundhog Day with an appearance by Flatiron Freddy at Chautauqua Park, where he will mysteriously forecast how much wintry weather remains.

Boulder Open Space and Mountain Parks rangers invite members of the public to a short hike and program designed around the stuffed marmot’s perennial search for his shadow. Program organizers suggest those in attendance will also learn how “the stars above have something to do with this day and why a real groundhog would never see his shadow in Colorado.”

Guests are asked to meet at 7:30 a.m. Friday at the Chautauqua Ranger Cottage. Free morning treats and coffee will be served. People are advised to dress warmly and leave their dogs at home.

And, as he does every year, Freddy will be changing the way he comes out of his burrow, according to informed sources.
