The Northern Highland is a geographical region in the north central United States covering much of the northern territory of the state of Wisconsin. The region stretches from the state border with Minnesota in the west to the Michigan border in the east, and from Douglas and Bayfield Counties in the north to Wood and Portage Counties in the south. While most of northern Wisconsin is within the Northern Highland region, a short belt of land along the coast of Lake Superior is not included in the area, and is instead part of the Lake Superior Lowland region. Outside Wisconsin the highland stretches northward in Canada through the Upper Peninsula of Michigan and the Canadian Shield in Northern Ontario and Quebec to Labrador and Hudson Bay. Geography The Northern Highland was once a mountain range similar to the Alps or Rocky Mountains of today. Over hundreds of millions of years, these mountains were worn and flattened out by erosion and glaciation. The region is mostly a smooth plain, but it remains higher than the rest of the state and some hilly regions continue to exist. Located near the center of the region, Timms Hill in Price County is the highest point in Wisconsin, at an elevation of feet above sea level. Other hills such as Rib Mountain also approach this elevation. Whether hilly or flat, most of the Northern Highland is covered in woodlands. The most common trees of the Northern Highland are the Sugar Maple, Aspen, Basswood, Hemlock, and Yellow Birch, as well as Red and White Pine. A large amount of the forestland in the region is included within the Chequamegon-Nicolet National Forest. State and county forests also cover a significant part of the region, and only a small portion of the land is devoted to agriculture. The largest city in the region is Wausau, with a population of 38,426. Other principal cities include Merrill, Rhinelander, and Ladysmith. Despite the absence of large cities, tourism is an important part of the local economy. The region’s numerous lakes and forests make it a popular destination for outdoor enthusiasts during the summer season. This is part of a northern Wisconsin area colloquially referred to as "up north." Northern Highland Lake District The Northern Highland Lake District consists of Lake Peter, Paul, and Tuesday. These lakes appeared during an ice age around 12,000 years ago. Wildlife The wildlife of the Northern
