Trillium Hollow at Rock Run Wilderness

93.175 acres in Adams County

Rock Run Wilderness Expansion. Trillium Hollow is a 93 acre tract contiguous to the Arc’s existing Rock Run holdings. It is located at the head of Trillium Branch, a tributary of Rock Run, on the upper elevations of the hill facing the Ohio River just east of Sandy Springs Cemetery. The tract is fully forested with trees dominated by oaks and hickories averaging 50-65 years old.

The missing piece. The richest wildflower-laden tributary in the entire Rock Run watershed is Trillium Hollow, a ravine named after its extensive colonies of Wake Robins. With its nearly vertical sides and astonishing depth, it is a nature lover’s dream! Unfortunately, it is virtually inaccessible other than sliding down on one’s backside. So, when the navigable head of Trillium Hollow was offered to us for sale by private land owners, we couldn’t have been more surprised and delighted!

Hiking Trails. This critical piece facilitates – for the first time ever – a hiking trail to originate from the planned trailhead on US-52 near Sandy Springs Campground, cross through the heart of the preserve along the Rock Run gorge, follow the rim of hills bordering the Ohio River, on through the Arc’s prickly pear sand fields, and finally end at the secondary trailhead at Sandy Springs Rest Stop. This will allow a trail to connect all of the Arc’s Rock Run holdings! We hope to have this trail open this year. Please check back for more information!

Trillium Hollow protects an additional .384 miles of forested stream corridors in one of Ohio’s most pristine and biologically rich aquatic ecosystems

Rock Run is currently a 779-acre Arc of Appalachia preserve region protecting the Appalachian hill country surrounding the exceptionally deep ravine of Rock Run – a two square mile pristine watershed that flows directly out of Shawnee Forest into the Ohio River. Rock Run lies near the southern borders of the Shawnee State Forest, north of the Ohio River, east of Rome, and west of Buena Vista.

Rock Run’s highly dissected hill-country and associated watershed is exceptionally scenic, highly biodiverse and completely forested. The hillsides reveal exposed layers of shale and sandstone. The lower elevations of the hills protect a fairly rare community in Ohio (more common along the Appalachian Mountain’s flanks) – a hemlock/black birch forest ecosystem. The upper elevations are covered in oak-hickory forests.

Since 2003, the Arc has been buying property in the watershed of Rock Run, picking up several parcels to date that had not been acquired by the Shawnee State Forest. The Arc’s long-term goal is for Rock Run to be one of the best protected watersheds in all of Ohio by preserving the watershed in its entirety. The acquisition of Trillium Hollow puts 95% of the watershed in conservation or preservation status.
