These weekly hikes will focus on the changes that take place in Merry Lea's woodlands and vernal ponds during a month's time. We will visit the woods near the Learning Center and its vernal ponds and Bear Lake Prairie and the north side of Onion Bottom. We'll watch as frogs, salamanders, buds, wildflowers and birds appear. Cost: $5 per person; $15 if paid April 6th for the series. Maximum per family: $15.
