Upper Yakima Basin

The Upper Yakima Basin spans the entire eastern half of the Mountains to Sound Greenway National Heritage Area, stretching from high alpine wilderness in the Cascades to high value agricultural lands in the Kittitas Valley near Ellensburg.  Rich in natural resources, communities like Roslyn and Cle Elum celebrate their mining and logging legacies even as tourism and outdoor recreation become more important parts of the local economy.
