Searles Nature Preserve ----------------------- Searles Nature Area is on the north side of Bolla Road in Augusta Township, southeast Washtenaw County. Take US-23 south to Willis Road. Go east and bear left on Bolla where Willis curves to the right. The marked entrance is easy to miss; it's on the north side of the road. The last I knew there was a sign marking the entrance, but it's easy to miss because it is parallel to the road rather than perpendicular. The footpath into the preserve is not well worn, so it's easy to miss, too, as you drive by. The Searles preserve is small--perhaps not more than an acre or two.
