Flowering Plants on the Fossil Hill Trail

April 27, 2004

This walk starts at the parking lot at the Sutherland Drive entrance to Shell Ridge Open Space. Start by turning left. It includes a short tour of the quarry in Quarry Hill to the left and then proceeds down the hill towards Indian Pond. At the fence line just before the pond, turn right onto the footpath. This path takes you to the road just above Bramhall Pond and then, staying right at each intersection, returns you to the parking lot at Sutherland Drive. For more thourough directions check out the Fossil Hill Recommended Hike.
