Data Quality Information:

Completeness report:
  Unknown. Density of trails in adjacent 1:100,000 scale quadrangles is obviously variable.
Horizontal Positional Accuracy Report:
  Approximate horizontal accuracy is 51 meters, assuming source data meets National Map Accuracy Standards.

    Title: 1:100,000-scale Digital Line Graphs
    Publication place: Reston, VA
    Publisher: U.S. Geological Survey
    Source scale denominator: 100000
    Source contribution: The data set was extracted from this source.
    Calendar date: 1990
  Process step:
    Convert DLG files to Arc/Info format. Performed by the Bureau of Land Management, Montana Office, exact date is unknown.
  Process date: 08/01/1997
  Process step:
    Select trails (minor codes = 211 or 212, major codes = 170) from DLG coverages, combine all quadrangles into one coverage, and project data to Albers. Performed at the State Library.
