A '''draw''' (US) or '''re-entrant''' (international) is a [[Terrain|terrain]] feature formed by two parallel [[Earth:Ridge|ridge]]s or spurs with low ground in between them. The area of low ground itself is the draw, and it is defined by the spurs surrounding it. Draws are similar to valleys on a smaller scale; however, while valleys are by nature parallel to a ridgeline, a draw is perpendicular to the ridge, and rises with the surrounding ground, disappearing up-slope. A draw is usually etched in a [[Earth:Hill|hillside]] by water flow, is usually dry, but many contain an ephemeral stream or loose rocks from eroded rockfall.

In a draw the ground always slopes downward from a draw in only one direction, and upward in the other three.<ref>http://www.globalsecurity.org/military/library/policy/army/fm/3-25-26/ch10.htm</ref><ref>http://www.armystudyguide.com/content/Prep_For_Basic_Training/Prep_for_basic_land_navigation/draw-minor-terrain-featur.shtml</ref> The slope on a draw is generally quite sharp, with a clearly established [[Earth:Fall line (topography)|fall line]] and characterized by a generally steep vertical drop over a short horizontal distance.
