In 1916, John Marin executed the present work in the Echo Lake District of the Kittatinny Mountains in Pennsylvania, near the Delaware Water Gap. In contrast to many of Marin’s bold and dynamic urban subjects, such as the Weehawken Sequence, completed in the same year, the present work possesses a tranquil, calm quality. Echo Lake District, Pennsylvania, showcases Marin’s shorthand strokes, reliance on geometric form, and innovative modernist stylizations. Marin’s composition possesses overlapping planes of color that diminish the boundary between foreground, middle ground, and background. Throughout his prolific career, Marin continuously reimagined the possibilities of watercolor as a medium, experimenting with a wealth of painterly techniques and increasingly modernist forms.
