These natural features are: the beach berm crest
, where the crest is present, and the wet/dry sand line or last high tide swash line, where there is no berm crest
The Service has decided to use recognizable natural beach features -- the beach berm crest
and/or the wet/dry sand line -- as the wilderness boundary and the point below which all vehicles must remain when on the beach.
Atzert said that vehicle access will be allowed only below the beach berm crest and below the wet/dry sand line, and only from Sept.
Therefore, the Service decided to use recognizable natural beach features -- the beach berm crest and the wet/dry sand line -- as wilderness boundary indicators.
