Jon Wallace will present the talk "Meteorites – Hunting and Identification," at the Rockland Public Library, 80 Union St., Thursday, June 15, at 6:30 p.m. See rocks that have fallen to Earth from asteroids, Mars, the Moon and comets. Find out how scientists and others search for them and details about the recent fireball seen over Maine. Participants will also get to start their own collection with a free meteorite specimen (while supplies last).

Wallace was an award-winning high school science teacher in Meriden, Conn., for over 32 years. He is past president of the Connecticut Association of Physics Teachers and was an instructor in Wesleyan University’s Project ASTRO program. He has managed the Naugatuck Valley Community College observatory and run many astronomy classes and training sessions throughout Connecticut.

He began collecting meteorites at this time to use when weather didn’t cooperate for observation sessions and found his passion for geology re-ignited. He has collected many specimens, as well as thin sections for study and education. Wallace has a bachelor's degree in geology from the University of Connecticut; a master's degree in environmental education from Southern Connecticut State University and a certificate of advanced study (sixth year) in science (astronomy) from Wesleyan University. He currently lives in Maine and gives free presentations in schools, libraries and other venues in the Freeport area.

The event is free and open to the public. For more information, call 594-0310.
