I scoped it out over Labor Day weekend and it's not in shape. There is exposed rock and it looks pretty thin.
The entiat ice fall looks doable, but there would be a little traversing and potentially a bit of scrambling mid-way up...
Scoped it out this past weekend. Didn't climb it as it's got at least two big schrunds, thin up top (scree and potential scrambling), and has a pretty indirect approach due to crevasses on the Boston. I'd say put it on the list for next year.
Just did Boston via the S. Face (see Beckey) this past weekend. Not a soul on the route and it's a kick in the pants. The ridge traverse from Sahale to Boston has a distinctively Alps feel with definitely Cascade quality rock. I recommend taking along a rope as it's three quick single rope rappels back to the notch -- all with decent quality anchors. Beats downclimbing.
