The 'M' was originally created as a collaborative project between the University of Wisconsin-Platteville's freshman class and the local community.
The structure is composed of approximately 400 tons of limestone.
The landmark is illuminated on specific occasions to celebrate academic milestones or homecoming events.
The site is situated on a private mound, but access to the landmark area is permitted for visitors through established paths.
Its scale makes it identifiable from aerial photography and satellite imagery of the region.
Platte Mound M is a massive, hillside letter 'M' constructed from whitewashed limestone rocks, serving as a prominent landmark for the University of Wisconsin-Platteville. Measuring approximately 240 feet in height and 210 feet in width, it is one of the largest collegiate monuments of its kind in the United States. The site offers panoramic views of the surrounding driftless region landscape from its elevated position on the Platte Mound. Originally built in 1936 by students, the monument undergoes regular maintenance and annual whitewashing to maintain its visibility. The surrounding area consists of hilly terrain characteristic of southwest Wisconsin's unglaciated topography. It serves as a symbol of school spirit and local pride, visible from several miles away in the Platteville valley.
From the base of the M looking upward to capture the scale, or from the valley road looking toward the mound to capture the landmark against the horizon.
Wear sturdy, closed-toe hiking shoes as the terrain leading up to the monument is steep, rocky, and uneven.
Bring binoculars if you wish to observe the geology of the surrounding Driftless Area from the top of the mound.
Visit during the early morning or late afternoon to avoid the lack of shade on the open hillside.
Do not attempt to visit during or immediately after heavy rain, as the hillside paths become extremely slippery and hazardous.
Stay on marked trails to avoid damaging the limestone structure; pack out all trash to preserve the natural hillside.
