Tidemark Gallery, 902 Main St./Route 220, will present a powerful show of new pastel paintings by Barbara Vanderbilt. “Rock Show” will open Saturday, June 7, with a 5 to 7 p.m. reception that coincides with receptions at the nearby Philippe Guillerm Gallery and Friendship’s Maine Coast Artist Gallery.

Asked why she chooses rocks as a favorite subject, Vanderbilt said, “It’s the strength — the timeless, elemental nature of the stone that I love.” That love shows in her work.
