Course Outline

Range Markers—Not Aligned

To help boaters navigate within channels, range markers have been erected in many Oregon rivers and bays.

  • These markers consist of widely separated, brightly painted pairs of markers, one taller than the other.
  • They are mounted on skeleton towers or on pilings and may be in the water or on shore.
  • Steering a course that keeps the two range markers lined up vertically while operating in a channel marked by buoys will keep the boat within the navigable channel.
  • Consult the appropriate navigation chart for locations of range markers.
