Traffic pattern
Pattern altitude is not published. Use standard 1,000 ft AGL for light piston aircraft unless the current FAA Chart Supplement says otherwise. Copalis State has no control tower, so pilots self-announce and self-sequence in the pattern. Right traffic is published for Runway 14. That means left traffic for Runway 32 unless local traffic or procedure calls for something different. Keep the runway surface in mind. It is sand, so performance and braking can vary with conditions.
Every end, one page
Each runway end has its own page with wind component, traffic pattern geometry and ILS for that specific direction.
