I would stay east of Cle Elum. I can't think of much around Easton. Snow could be an issue if you try to get up in the higher elevations on the National Forest. You might try the Teanaway valley, but watch out for the extra large coyotes.
I think you'd be better off further east. Try the Wenas and LT Murray Wildlife Areas. You can pick up the green dot maps at the WDFW office in Eburg.
Although it may be even better to concentrate on the area you already know, north of Ellenburg, especially since you only have two days to hunt.
