Overview

Description

Why TNC Chose This Site

Green’s Bluff is a picturesque nature preserve located in Owen County, comprised of two separate properties, each with its own loop trail. Green's Bluff features an upland forest, rocky bluffs, and a lush floodplain forest along Raccoon Creek. The steep bluffs are home to a grove of eastern hemlock trees, a species that is only found in Indiana on steep, north-facing slopes that provide a shady, cool environment. The preserve also features cave entrances and remnants of an old grist mill. This preserve was established in 1985, and as of 2021, the preserve is 1,134 acres.
 
What's New at Green's Bluff

TNC has improved the existing trail at Green’s Bluff and added interpretive signage to enhance visitor enjoyment. In 2020 and 2021, TNC also created a second trail and ten acres of pollinator habitat at the newer acquisition.

The new trail and pollinator habitat were made possible by a grant from the Duke Energy Foundation. Duke has been a long-time supporter of TNC and conservation projects in Indiana.

  • The dominant features of Green’s Bluff are the steep, rugged sandstone cliffs along Raccoon Creek and the associated plant communities, including remnant groves of hemlock trees. Thick beech-maple woods grow in the rugged ravines while sycamore trees tower over the scouring rush (horsetails) which flourish along the creek.

    Green’s Bluff is one of two Indiana sites where mountain spleenwort can be found. Competing for available soil and moisture in the deep shade are the large, thick leathery fronds of marginal shield fern, maidenhair fern, plantain-leaved sedge (a showy species as far as sedges go), sharp-lobed hepatica and a variety of other ferns and wildflowers. Other rare plants include hay-scented fern, goldenseal and spotted wintergreen.

    Spring is a great time to view the vast array of stunning wildflowers, and the view from atop the sandstone bluff reveals a wooded landscape that feels like true wilderness.

    Green’s Bluff also boasts a nesting rookery of great blue herons—tall, regal wading birds that search the waters of nearby Raccoon Creek and the larger White River further downstream for food. Close approach of their nesting colony by human intruders will be met with the loud, raucous calls of this highly gregarious species. To minimize disturbance during their nesting season, the herons should be enjoyed from a distance.

    In the summer months, the wood thrush, red-eyed vireo, Acadian flycatcher, scarlet tanager and Louisiana woodthrush can also be found either nesting high in the trees or nesting in the brush. Leopard frogs, green frogs and banded water snakes are among the amphibians and reptiles found at the preserve. Various mollusks, crustaceans and fish also make their home in the meandering Raccoon Creek.

    As fall approaches, the summer colors fade to red, orange and gold. Migratory birds are on the move, and you’re likely to spot several species of raptors.

    When winter arrives, snow and ice blanket the area, making it a welcome respite for visitors seeking the peace and quiet of the season. 

    NOTE: Many of our preserves allow deer hunting from October through the first week of January, so wearing blaze orange is suggested when hiking in these areas during hunting season.

  • Green’s Bluff is an ideal spot to enjoy the sights and sounds of nature, hike, take photos and bird watch.

    The North Loop Trail is a 1.2-mile moderate loop trail through the northern section of Green’s Bluff. The gravel parking area at the trailhead can accommodate 5 vehicles, with room for a few more along the road next to the cemetery. The trail overlooks hemlock bluffs above Raccoon Creek, then descends a steep slope to continue along the face of the bluff down to the creek. This portion of the trail can be quite rugged. The trail continues along the creek, where a sharp eye may notice the stone foundation of James Green’s grist mill from the late 1800s.

    The Raccoon Woods Trail is a 1.4-mile moderate loop trail through the newer southern section of Green’s Bluff. The gravel parking area at the trailhead can accommodate 5 vehicles. This is an excellent trail for spotting migrating birds in the spring and admiring colorful leaves in the fall. After starting in a clearing where TNC has planted rows of oak trees, the trail winds through deep woods with many mature oak, beech and hickory trees. As it descends into steep ravines, the trail crosses spring-fed creeks. Climbing out of the ravines, it offers views of the forest canopy. At the far end of the loop, the trail rises into an open area where TNC is attracting birds and insects with pollinator plantings.

    The North Loop Trail at Green's Bluff can be quite rugged. The Raccoon Woods Trail is more moderate. New interpretive signs, funded by the Duke Energy Foundation, are found along both trails.

    It’s just a ten-minute drive between the two trailheads, so why not visit both trails while you’re in the area?
