Summit Rock on Rib Mountain Summit Rock on Rib Mountain
Rib Mountain (long ago “Rib Hill”) consists of an impressive ridge almost 4 miles in length that peaks at the summit of Rib Mountain (1924 ft above sea level). Rib Mountain is not the highest point above sea level in the state. That honor is due Timm's Hill (1952 ft above sea level). However Rib Mountain does stand higher above the surrounding terrain than any other summit in the state, rising nearly 750 above the Wisconsin River (approximately 1170 ft above sea level) near the eastern foot of the mountain. It is the most impressive mountain in the state. Depending on what source one chooses to refer to, official prominence runs from 630 feet to 740 feet. In an interesting misinterpretation, a local guidebook once claimed that Rib Mountain "towers 2000 ft above Wausau" -- a statement that clearly confuses "elevation", or height above sea level, with"relief"!

Though this grand mountain is actually one of the oldest geologic formations on earth, Rib Mountain is not volcanic in nature, as the shape of the terrain might suggest from some angles. As local geologists like to point out, "Rib Mountain is not volcanic in any way, shape or form".  In reality, Rib Mountain is a large block of quartzite that has stood tall while the other sedimentary rock of the area has weathered away.

In the pursuit of county highpointing, Rib Mountain is widely considered the hardest county (Marathon) highpoint in Wisconsin. While the scramble to the top of the quartzite outcrop is probably only class 3, it certainly beats the socks off of walking through a muddy corn field.


Since Rib Mountain State Park was established in 1934, the park has grown to nearly 1,600 acres. On the north side of the mountain is the Granite Peak Ski Area, one of the best ski runs in the midwest. The state park has developed shelters, an observation tower and decks, picnic areas and an amphitheater for the benefit of visitors.

There is a vehicle admission fee required for the park. You can drive almost the whole way to the top if you wish, or you may stop at either the Yellow Trail trailhead or take the paved walkway next to the road and hike up to the summit rock, which has a 60' observation tower next to it, as well as the USGS Benchmark nearby.

Children refers to the set of objects that logically fall under a given object. For example, the Aconcagua mountain page is a child of the 'Aconcagua Group' and the 'Seven Summits.' The Aconcagua mountain itself has many routes, photos, and trip reports as children.



Parents refers to a larger category under which an object falls. For example, theAconcagua mountain page has the 'Aconcagua Group' and the 'Seven Summits' asparents and is a parent itself to many routes, photos, and Trip Reports.
