The vibrant landscape scene, Mountain Lake—Autumn, was executed during Hartley’s earliest painting trips to Maine. His interest in the vast mountainous landscape of his native state is captured within this fall scene. Mountain Lake—Autumn reveals Hartley’s style of around 1910, when his landscapes had bright, fauve-like color reminiscent of Matisse and heavily textured brushstrokes that provide solidity and weight to the scene. In Mountain Lake—Autumn, Hartley applies short, closely-knit strokes that enabled him to use color to its fullest potential. Here, he abandons framing devices such as the vertical trees of his earlier Maine mountain series, thus attaining an expressive, lively effect.
