In this chapter,
(1) “scenic park” means relatively spacious areas of outstanding natural significance, where major values are in their natural geological, faunal, or floral characteristics, the purpose of which is directed primarily toward the preservation of its outstanding natural features and where development is minimal and only for the purpose of making the areas available for public enjoyment in a manner consistent with the preservation of the natural values such as camping, picnicking, sightseeing, nature study, hiking, riding, and related activities which involve no major modification of the land, forests, or waters, and without extensive introduction of artificial features or forms of recreational development that are primarily of urban character;
(2) “wilderness park” means an area whose predominant character is the result of the interplay of natural processes, large enough and so situated as to be unaffected, except in minor ways, by what takes place in the nonwilderness around it, a physical condition which activates the innermost emotions of the observer and where development of man-made objects will be strictly limited and depend entirely on good taste and judgment so that the wilderness values are not lost.
