In levelling the terraces in Lochaber, all, I believe, have been taken in Glen Roy, nearly N. and S. There should be levels taken at right angles to this line and to the Great Glen of Scotland or chief line of elevation.

A dirt-stained finger traced a path from the round contours of their current perch to the more linear elevation lines that marked Tomlinson's little ridge.

Due to the nature of the base maps used for the background and time-cost restrictions, elevation lines (contours) were left in feet except for the 1:150,000 maps where they are in meters.

Edwards and his party kept to the five-hundred-foot elevation line, which kept them at least two miles from the gravel coast road, with mountains at their backs and a good long field of view.

SQUINTING in the late afternoon sun at a topographic map covered with tiny elevation lines, Jeff Bury, an assistant professor of geography at San Francisco State University, had to admit the obvious.

IV, where the lowest elevation line is numbered 5 changed from 4 and the elevations to either side are 6 to the north, the plateau of Himlad, and 7 south the raised plain of the Estolad, indicating sharp rises to the valley walls.
