Cathance River Education Alliance will hold open hours at the Ecology Center from 11 a.m. to 3 p.m. each Sunday in June. Discover the off-grid center’s “green” features and its use. Explore field guides, specimens and geological information, or watch footage from the remote wildlife camera. There are also more than five miles of trails, showcasing a richly diverse wild river habitat, that are open to the public from dawn to dusk.
