Rib Mountain State Park

Static map displayed.
Rib Mountain State Park is on a long ridge of quartzite just southwest of Wausau, beside US 51. The quartzite is about 1.7 billion years old, one of the oldest rock formations on earth, and it has worn away far more slowly than the land around it, so the ridge now rises high above the plain around Wausau. The Mountain View panel at the overlook puts it at 1,940 feet above sea level and calls it the third-highest point in Wisconsin; the older bronze plaque at the summit gives the same height, from the years when it was thought to be the highest point in the state. The Kiwanis Club of Wausau bought land at the top in 1922, the estate of Jacob Gensman gave 40 acres in 1923, and the land became a state park in 1927. In the 1930s, the Civilian Conservation Corps built paths and a campground here and cleared the first ski slopes, and Granite Peak Ski Area still runs on the north face. I stopped there in the late morning of August 8, 2021, a gray Sunday, on my way north to Ashland, and went on to Council Grounds State Park afterward. I walked along the top of the ski runs, past boulders of quartzite and slopes of late-summer wildflowers, to the rock formations called the Queen’s Chair and the King’s Chair, and climbed the observation tower for the view over the treetops to Wausau and the Wisconsin River.

3 The Queen’s Chair, one of the quartzite rock formations near the summit: great angular blocks of gray rock, streaked with rust, piled on top of one another beside a trail of packed earth, with a small brown sign on a post at the left reading “Queen’s Chair,” more boulders scattered around it, and leafy trees behind.

A bronze plaque, green with age and topped by the Wisconsin coat of arms between spread wings, set into a pink and gray boulder near the summit. It reads “Rib Mountain State Park. The summit of this rock is the highest known point in the state, 1940 feet above sea level,” and says that the land, forty acres in area, was presented on January 26, 1923, by the estate of Jacob Gensman, that the Kiwanis Club of Wausau enlarged the park to 160 acres, and that the area was once a sandy beach whose sand hardened into quartzite and was raised to its present height.

The view from the observation tower at the summit: a sea of green treetops, with a few white birch trunks among them, falls away below a brown wooden railing at the lower right, and beyond the forest the land around Wausau spreads out flat to the horizon, with roads, fields, and buildings under a pale, overcast sky.
