Here's not just a line, but a paragraph of description of the area around Pendleton, Oregon in the Umatilla Indian Reservation. That part of the state really is beautiful.
Buffy sat at the top of a hill, overlooking a steep valley, carved out by thousands of years of rainwater off the Blue Mountains, not really seeing the sea of sage and greenery around her. A recent rainstorm had come through, turning the prairie grass green and vibrant, but she could not appreciate the beauty all around her. The line of green that indicated the Umatilla River was right in front of her, but it held no sway over her as it normally did.
