  • Cape LookoutJockeys RidgeCape HatterasLocation of the ParkNags HeadOuter Banks, N.C.

  • Park FactsMedano large hill of shifting sand that lacks vegetation

    Park contains 10.3 million yd3 of sand

    Park covers 414 acres

    Dune height varies from 110-140 feet

    Important tourist attraction: hosts more than 900,000 tourists each year

    Tourist activities: Hang Gliding, Kite Flying, Hiking, etc.

  • Jockeys Ridge is on the MoveWind has caused the park to migrateDirection of wind shifts throughout year

    Summer: wind from the SWWinter and Fall: from the NEPredominant direction of Migration: Park is moving to the SW

  • Management IssuesDevelopment North of the park has cut off the source of new sand

    Migration of the dune field outside the limits of the Park:Entrepreneurs hauling away sand for commercial useEncroachment onto Neighbors property

    Human impacts: Recreational activities

  • Management SolutionsDo Nothing not really a solution

    Haul sand away on a regular basis 50,000 yd3 could be moved every five years from the S-end and put on the N-end

    Vegetate the Dune:Entire dune fieldSouthern end of the Park

    Sand Fences

  • Problems with Management OptionsHauling Sand away is expensive and would have to be done on a regular basis

    Vegetating the dune field would stabilize the system but would defeat the purpose of having an active dune

    Sand fences and old Christmas trees emplaced along S-end ofpark have been covered with migrating sandWright Brothers Memorial in nearby KillDevil Hills once had a migratingdune.
