Matthiessen State Park is anIllinoisstate park located a few miles south of the more famousStarved Rock State Park. The main entrances to both parks are located on Illinois State Route 178.
The park is nearOglesby, inLaSalle County,Illinois, United States. It is named forFrederick William Matthiessen, who had originally owned the 176 acres (71 ha) of property that is at the core of the current park.[2] Two mansions, several cottages, a garage, and a private fire station were built here by Matthiessen for his family. It was an estate that hosted a private park known as "Deer Park".[3] The park was donated to Illinois by Matthiessen's heirs, following his death in 1918, and was renamed in his honor in 1943. Since then, land was added, growing the park to 1,938 acres (784 ha).[2] The last building of the former estate was destroyed in 1981, although some of the concrete stairs leading into the canyon are of the original construction.[3]
The park is centered on a stream that flows from Matthiessen Lake to theVermilion River. The stream has eroded partway through the sandstone layers, leaving interesting rock formations and drops. The Upper Dells begin at Matthiessen Lake with the Lake Falls, which drop into the canyon below, and continue downstream to the 45-foot-tall (14 m) Cascade Falls where the Lower Dells begin. The interesting coloration of many of the canyons is the result of minerals in the groundwater. Many mineral springs exist throughout the park, providingsalt lick spots for the large deer population.[4]
The cool and damp canyons provide an ideal habitat for many species ofmosses,liverworts, andferns. On top of the bluffs that form the canyons can be foundblack oak (Quercus velutina),red cedar (Juniperus virginiana), andwhite oak (Quercus alba) trees, which thrive in the sandy soil. The park contains several species generally found farther north, such as theCanada yew (Taxus canadensis) andCanada mayflower (Maianthemum canadense).[3]
Frogs, toads, andsalamanders live on the canyon floors, while bird species such as thecliff swallow nest in the eroded canyon walls.[5] As the former name of "Deer Park" might suggest, the area is home to a very large population ofwhite-tail deer.
Today there are five miles of marked hiking trails, in addition to nine miles ofmountain biking and equestrian trails.[6] ThePlum Island Eagle Sanctuary is located nearby.
