| Turnbull's 17,908 acres reflect a diverse landscape carved by massive Ice Age floods that scoured potholes, sloughs, and deep canyons out of the underlying basalt more than 15,000 years ago. Located within the Pacific Flyway, the refuge includes deep permanent sloughs, semi-permanent potholes, and seasonal wetlands. This mosaic provides important habitat for migrating and breeding waterfowl and other water birds. |
