The Lee Library will welcome Christy Butler, a Cheshire-based photographer and co-author of "Rockachusetts: An Explorer's Guide to Amazing Boulders of Massachusetts," from 6:30 to 7:30 p.m. Tuesday, Aug. 9.

While the book covers all of Massachusetts, this multi-media presentation will specifically focus on the glacial boulders, balanced rocks and other rocky landmarks in the Berkshires.

A question and answer and booksigning will follow. The public is invited.
