Twelve kinds of lichen had a tenacious grip on the sheer granite cliff where a memorial to Walt Whitman had been carved. Removing the growth without damaging the inscription required a special work platform, careful research, and on-site testing. Similar removal techniques could be used on lichen-encrusted granite monuments or buildings. [ABSTRACT FROM AUTHOR] |
