Blue Mounds State Park puts on a fall show

Rock alignment at Blue Mounds State Park.
A mysterious rock alignment runs exactly east and west at the park. Archeologists agree the alignment is man made, but disagree on who made it. Theories range from Native Americans, neighboring farmers, or mining companies marking their boundaries. Here, it's shown on the fall equinox, with the sun setting directly to the west.

Photojournalist Jackson Forderer covered the bison roundup last week. Then he turned his camera around to capture the rest of the park as it neared peak fall color.
