Lewis Falls Lewis Falls is hard to miss when you enter or depart the park from the South Entrance. A short distance south of Lewis Lake, the impressive 29-foot falls plunges toward the highway. Do take time to stop and observe this waterfall and then explore the way the Lewis River cuts its impressive canyon to the south. We often spot ouzels and other water loving birds in the stream below the falls. We especially like Lewis Falls in the winter, when mounds of soft snow are often perched on the trees alongside the waterfall. The very mention of the the word Wyoming evokes the essence of the American West. Wyoming is all that innumerable movies, novels and legends have tried to capture. This Western Spirit thrives to this day in the Cowboy State. The name Wyoming has its origins in an Algonquin word meaning \"large prairie place \".
