The length and straightness of the Pike ridge can be appreciated best by following it northward. North of the o'neil road, the trend of the ridge is at first northerly. Then it turns slightly. East of north until it reaches one of its higher elevations or peaks, beyond which it returns to its former northerly course. Clumps of red haw and wild rose, with their protecting thorns and prickles, are scattered along the crest. Grape and woodbine spread among the lower branches of the trees. Northward, a fence crosses the ridge, and beyond the fence, the ridge descends rapidly, being crossed by a natural depression or gap, beyond which the ridge continues again. The Nollman farm lane passes through the gap in a westerly direction. North of the gap there are two ridges, but, of these, the eastern ridge is in more direct alignment with the Pike ridge, which we have been following from the south, and is regarded as an extension of the latter. Northward this eastern ridge becomes distinctly hummocky, but a glance down the valley, between this eastern or Pike ridge and the western or Nollman ridge,' will reveal the ridge-like character of the succession of hummocks bordering the western side of the Cincinnati pike.
