Draw (terrain)
[Image:TerrainDraw.gif|right|thumb|320px|Example on a topographical map, and how it would look in the real world.]
A draw, sometimes known as a re-entrant in orienteering, is a terrain feature formed by two parallel ridges or spurs with low ground in between them. The long area of downward sloping low ground itself is the draw, and it is defined by the spurs surrounding it.
Characteristics
Draws are usually etched in a hillside by water flow, are usually dry, but many contain an ephemeral stream or loose rocks from eroded rockfall. In a draw the ground always slopes downward in only one direction, and upward in the other three. The slope on a draw is generally quite sharp, with a clearly established fall line and characterized by a generally steep vertical drop over a short horizontal distance. There is essentially no level ground and little or no maneuver room within the draw. On a topographical map, the contour lines depicting a draw are U-shaped or V-shaped, pointing toward high ground.A draw can be conceptually thought of as the inverse of a spur, much how a valley can be considered the inverse of a ridgeline. In land navigation training, students are typically taught to visualize these features by making a closed fist with their hand; the knuckles form "hills" individually, and from there the fingers represent spurs while the gaps in between fingers represent draws.
