Draw is indicated by contour lines shaped how?

• A. Concentric circles
• B. U or V shaped, pointing toward high ground
• C. Hourglass
• D. Tick marks extending to roadbed

Answer: (B)

A draw is a drainage feature, so the map shows it by how the contour lines bend where a stream would run. When contour lines cross a valley or drainage, they form a V (or a narrow U) that points uphill toward higher ground. The tip of the V points toward the source of the drainage, indicating the direction water would flow from. That pattern—V-shaped (or narrow U) lines pointing toward the high ground—signal a draw. Concentric circles would mean a hill or peak, not a drainage. An hourglass shape indicates a saddle or pass between ridges, not a drainage channel. Tick marks extending to a roadbed don’t describe a drainage feature on the terrain itself.
