how does Victor's trip affect his spirits

In Chapter Nine, Victor seeks escape from his misery by traveling through the Alpine valley of Chamonix, in which he had often vacationed as a boy. Victor is awestruck by the overwhelming grandeur of the landscape, and views it as proof of the existence of an omnipotent god. The hard physical exercise exhausts him, and he is able to take refuge in sleep for the first time since the execution of Justine.
