Mountain Landscape with River (Stave?) and Trees (from Sketchbook)

The image shows a simple pencil sketch on paper featuring a mountain landscape with a river and trees. The sketch is done on a piece of paper with rounded corners and holes punched along the top edge. The paper has a rough texture and appears to have been torn or cut from a sketchbook. The sketch itself depicts a simple outline of mountains, a river, and trees. The mountains are drawn in the background, with the river flowing through the center of the page. The trees are scattered throughout the landscape, with some appearing to be in the foreground and others in the background. The entire sketch is drawn in pencil and is quite faint. The background of the image is plain white.
