Battle Creek flows through Battle Creek Regional Park, cutting a wide gorge through sandstone bluffs, and both the creek and the park take their names from the Battle of Kaposia. By the 1750s, Kaposia was the seasonal Mdewakanton Dakota village of a succession of chiefs known as Little Crow, and although treaties of 1837 and 1852 shifted village locations, the earliest village stood on the east bank of the Mississippi below present-day Indian Mounds Park in St. Paul. An 1842 battle between the Dakota and Ojibwe above Battle Creek was recorded by nearby fur traders, farmers, missionaries, and Fort Snelling soldiers. Pig's Eye Lake, fed by Battle Creek, was then a quiet floodplain lake along the main channel of the Mississippi River, and in the late 1830s French Canadian voyageurs settled and farmed parts of the river bottomlands they called the Grand Marais, or Great Marsh. By the 1880s, the lake and bluffs around Battle Creek had become a popular destination for hikers, picnickers, artists, and fishermen, with St. Paul residents reaching the area by streetcar to Indian Mounds Park and then walking the next two miles. When railroad construction along the edge of the Point Douglas (Hastings) Road threatened to bring industry to the area, St. Paul citizens worked to preserve the forested bluffs along the lower creek. In 1922, William McMurray donated an initial 25 acres for Battle Creek Park, where a rustic log bridge and picnic pavilion designed by St. Paul City Architect Clarence W. "Cap" Wigington were built while most of the land remained in its natural state. In the 1930s, the Works Progress Administration built limestone walls along the creek, and after flooding and erosion scoured the park's fragile forested bluffs, stabilization and reforestation began in the 1940s. During the 1960s, Ramsey County acquired additional property north and south of the original park. South of the present-day park, the picturesque setting and commuter rail connection to downtown St. Paul inspired real estate dealers in the late 1880s to lay out Burlington Heights as a commuter suburb on the Chicago, Burlington and Quincy Railroad, with two stations providing six daily trains to St. Paul. Opposite the park today, the river landscape mixes wild, urban, and industrial land uses: Pig's Eye Lake divides the main navigation channel and a busy barge fleeting area, the Twin Cities' first primary sewage treatment plant was built there in 1938, the surrounding habitat remains mainly floodplain forest that is home to bald eagles, and a 100-acre island at the lake's south end supports a Minnesota Scientific and Natural Area with the region's largest heron rookery.
