Vernon-Douglas State Nature Preserve
Vernon-Douglas State Nature Preserve is located within a rugged, steep, forested section of Hardin County. This 730-acre preserve protects one of the most mature second-growth forests in the Knobs physiographic region. Hall Hollow, a north-facing valley in the preserve, supports a rich array of spring wildflowers. A trail system passes through the valley bottom to the dry ridges above Hall Hollow. A spur trail takes hikers onto a narrow point locally known as "the pinnacle," which provides a bird's-eye view of the Younger Creek valley. The forest features mature stands of sugar maple, beech and tulip poplar. Owned by one family from the early 1900's until the 1970's when it became an Audubon Sanctuary, it is now protected in perpetuity as a state nature preserve.
