A broad mountain rises in the upper half of the composition, its peak rendered in cool blue and white tones that stand out against a sky of shifting greens and greys. No figures or buildings interrupt the view, and the entire scene is constructed from short, visible brushstrokes that create a sense of vibration and movement across the surface. The foreground is a dense weave of darker greens and browns, with touches of blue and lighter yellow, evoking thick vegetation or undergrowth.

The brushwork is loose and open, with areas where the canvas shows through, especially around the edges, lending an unfinished quality to the painting. The sky occupies nearly half the canvas, its color shifting from blue at the horizon to a more muted greenish-grey above, with broad, horizontal strokes that echo the mountain's silhouette. The composition is anchored by the horizontal line of the mountain ridge, dividing the canvas into two bands: the sky above and the land below.

Cézanne uses a palette dominated by greens and blues, punctuated by warm ochres and browns, creating a harmonious balance between cool and warm tones. The painting’s structure emerges from the accumulation of brushstrokes, each mark distinct, with little blending, so that the surface shimmers with energy. In the lower right corner, the paint is applied more thinly, revealing patches of the bare canvas beneath the green and brown strokes.

The left edge of the composition is marked by a vertical band of darker green, contrasting with lighter, more open brushwork nearby. A pale, diagonal streak of light blue runs along the left slope of the mountain, suggesting reflected light. The upper left and upper right corners of the painting feature loosely brushed areas of green and grey, giving a sense of atmospheric haze.

Amid the middle ground, ochre and beige blocks are interspersed with greens, forming irregular horizontal bands that break up the vegetation. Lines of blue and green in the lower center of the painting overlap, creating a layered effect that suggests depth in the landscape. The genre is landscape painting, focusing entirely on the natural world without human presence.
