"Whitefish Falls," circa 1970, by Tom Roberts is a painting that captures the dynamic beauty of a waterfall and its surrounding environment. Roberts' skillful use of impasto technique is evident, with thick, textured strokes of paint that give the composition a vibrant and lively quality.

The painting features a series of birch trees in the foreground, their distinctive white bark marked with black standing out against the darker backdrop of the pine trees. The birches are rendered with vertical strokes, drawing the viewer's eye upward and emphasizing their height and slender form.

The waterfall itself cascades over a rocky ledge, depicted in whites and light blues, contrasting sharply with the earthy tones of the surrounding rocks and vegetation. The movement of the water is suggested by the directionality of the brushstrokes, which flow downwards and create a sense of rushing energy.

The reflection of the scene in the water below is captured with horizontal strokes of color, mirroring the hues of the trees and sky and adding to the sense of depth and tranquility.

Roberts' portrayal of the Canadian landscape is both realistic and emotive, with a focus on the interplay of light, color, and texture. "Whitefish Falls" invites the viewer to experience the wilderness' serene beauty and the power of natural elements such as water in motion. It's a snapshot of the rugged Canadian Shield, known for its dense forests and abundant waterways.
