Study of Rocks in a Landscape (from Sketchbook)

Black and white pencil drawing of a landscape with a large rock formation. The rock formation is in the center of the image, with vertical lines indicating its texture. The rock is dark in color and has a rough, jagged appearance. There are some lighter areas on the rock, possibly indicating snow or lighter-colored minerals. In front of the rock, there is some grass and other vegetation. The background of the image is a flat, light-colored area that could be a field or a body of water. The drawing is in a sketchbook with a black line border.
