      <abstract>Montana's townships, including townships "protracted" through unsurveyed areas by the BLM or Forest Service.  These features were digitized by the Bureau of Land Management from 1:100,000 scale maps.  The Montana State Library combined the individual quadrangles into a single layer, edgematched the features, and populated the attribute fields.</abstract>
