Description: 
Cap Sauers Holdings Nature Preserve, at 1520 acres, is the largest nature preserve in northeastern Illinois. Dominant geological features include the rolling topography typical of the Valparaiso Moraine of the Morainal Division of northeastern Illinois and an esker. The Visitation Esker is one of the best defined examples of this glacial feature in the state. Most of the site is composed of young upland forests, and disturbed prairie and oak savanna communities. Much of the former prairie and oak savanna communities are now threatened by brushy native and non-native species that have advanced because fire has been suppressed. The Forest Preserve District of Cook County and The Nature Conservancy have embarked upon an ambitious project to restore much of this site to its presettlement condition.
