WGS84/NAD27 converter
Most on-line map services and GPS's use the WGS84 datum, but the USGS topo maps are published in the NAD27 datum. The 1 kilometer UTM grid on the 7.5' quads is useful for off-trail adventures. Use a yardstick to draw in the grid lines (see example), then set your GPS readouts to NAD27 and UTM.
