"Prospect Lake, Muskoka, c 1935" is a serene oil on board painting by Peter Clapham Sheppard, an artist who contributed richly to Canadian art from 1882 to 1965. The painting, modest in size at 10.5 x 13.75 inches, carries the artist's signature on the bottom right.

Sheppard's work here captures the peaceful essence of Prospect Lake in the Muskoka region, known for its natural beauty and as a retreat from the bustle of city life. The composition features a wide expanse of water flanked by clusters of evergreen trees, with the distant shoreline drawing the eye towards the horizon. Above, a dynamic sky filled with billowing clouds suggests the ever-changing conditions of the Canadian landscape.

The artist's use of light and shadow, along with a palette of soft blues, greens, and earth tones, conveys the reflective quality of the water and the lushness of the surrounding forest. The brushwork is executed with a delicate balance of detail and impressionistic flair, inviting the viewer to experience the tranquility and freshness of the lakeside setting.
