A vast expanse of water surges over the edge of a cliff, forming the sweeping arc of Horseshoe Falls at Niagara. The entire foreground is dominated by churning, foamy rapids, painted with energetic brushwork that captures the turbulence and motion of the river just before it plunges. At the lower left, a dark, broken tree branch juts from the water, contrasting sharply with the luminous spray and adding a sense of scale to the immense scene.

The falls themselves stretch across nearly the entire width of the canvas, their curtain of water rendered in luminous whites, pale yellows, and subtle blues, with the crest tinged in green as sunlight filters through the torrent. Beyond the falls, a low, wooded shoreline runs along the horizon, painted in warm earth tones and greens that recede into the distance under a wide, cloud-filled sky. The sky above is a dramatic sweep of blue and violet, with dense, reddish clouds gathering at upper right, suggesting a moment of shifting weather and late afternoon light.

The composition is panoramic, with the falls placed slightly above center and the river leading the viewer’s gaze from the foreground into the heart of the spectacle. A faint rainbow arcs through the mist at the base of the falls, with its colors subtly blending into the surrounding spray. On the far left edge, the water appears almost translucent as it tumbles over the precipice, catching soft highlights from the sky.

The upper right corner is filled with dense, purple and ochre clouds, their edges sharply defined against the blue sky. The distant shoreline is dotted with small, indistinct trees, their forms loosely suggested with dabs of green and brown paint. Light falls most strongly on the crest of the falls and the mist below, creating a luminous, almost glowing effect in these areas.

The paint handling in the foreground water is vigorous, with swirling, curved brushstrokes that convey the force and direction of the current.
