Imagine a narrow, dirt path winding through a forest. You can feel the imagined uneven surface of the path. Tall, straight tree trunks rise up on either side, their rough bark within reach. You can feel the imagined texture of the bark. Branches and leaves create a dense canopy overhead, blocking out much of the light. Across the path, a large, fallen tree lies diagonally, creating an obstacle. You can feel the imagined rough texture of the fallen trunk and its many smaller branches sticking out. The scene evokes a sense of being deep within a forest, with a natural obstacle blocking the way.
