Begin at the Carrigan Drive entrance to Centennial woods. Follow the trail for approximately five minutes. You will pass over several man-made “bridges” on your way. When the trail splits, stay right. There should be a steep trail leading up a hill. Follow this trail up to when it is just beginning to incline then stop. Turn left off the trail into the forest. Climb over two large fallen Eastern Hemlock trees, and the plot will be several paces ahead.
