The support is a medium-weight, plain-weave fabric that has been lined. The original tacking margins have been removed, but cusping is visible along all four edges. The ground is thin and white. \rUnderdrawing is visible in the trees at the left, and infrared reflectography reveals further underdrawing along the contour of the mountains. Using a fairly elaborate layering system, the paint was applied thinly in the sky and lake and thicker in the mountains and foreground. A pentimento in the lake has been heavily inpainted. There are scattered small losses throughout, and the surface of the lake appears abraded and worn. The widespread traction crackle and wrinkling of the paint film are due to the artist's technique. In 1978 the painting was relined, discolored varnish was thinned, and the painting was restored. The varnish has become yellowed and milky.
