Roche-A-Cri Mound looks so out of place.
A steep, tree-covered mound of blocky white dolomite and orange sandstone, it rises abruptly 300 feet out of the almost entirely flat countryside of central Wisconsin.
When the last glacier plowed through and leveled most of the state, it stopped short of Roche-A-Cri. The mound stood as an island in Glacial Lake Wisconsin, a 70-mile-long, 160-foot-deep lake that formed when ice near the Wisconsin Dells blocked glacial water from draining down the Wisconsin River.
But the seemingly out-of-place mound is only the beginning of curious things at Roche-A-Cri State Park.
At the base of the bluff, ancient petroglyphs and pictographs are scratched and painted onto the bluff's soft sandstone.
The carvings date back to before 900 A.D., while the pictographs — now mostly faded — are more recent, dating back 400 or 500 years.
"We have the only accessible rock art in Wisconsin — it's accessible to all people," said Heather Wolf, property manager for the park. "A lot of people come from all over the U.S. and all over the world to see both [the mound and the art]."
Across the centuries
More modern graffiti — including from early European settlers — has obscured some of the historical etchings. One, which reads "A.V. DEAN. N.Y. 1861." is at least a dozen feet up the rock face. A sign at the site says the height suggests the men were on horseback when they carved their names.
