no place [Washington DC?]: Hawaii Volcanoes National Park / National Park Service, no date, circa 1980. Paperback. 75p., line maps (some with spot-color guides), tables and b&w site photos, 11x8.5 inch leaves softbound in utilitarian fashion (punchholed for a plastic comb but stapled instead), covers have picked up mild soil and an ownership name in red ink. Quite sound, a very good copy. A prefatory note warns that the content has been neither approved nor disapproved and constitutes background information that should be useful for fuller treatments.
