Visit Glacial Heritage Preserve, open to the public just this one day of the year. It is a restored prairie that may now look much the way it was when Lewis and Clark arrived in the west. Once prairies were a predominate ecosystem stretching from British Columbia to California. Now about 3% of prairie habitat remains. On the 1,000 acre Preserve you can see a vast array of the plants and animals that are found on prairies. The celebration features a hayride, children's games, native plant identification workshops, educational booths, a 4 mile walking trail, early morning bird walk (weather permitting, up to 70 species of birds can be sighted).
