Winter Bouldering options in Idaho

Hi Folks, looking for some winter bouldering options in Idaho. Any help appreciated. Thanks!

The channel up by Hailey. City of Rocks & Castle Rock as well.

There's stuff along Salmon River by Riggins, especially upstream along the salmon River road. Swan Falls, about .5 hr south of boise(kuna) is good year round, see the Epeldi/Bernstrom guide by same name.

Table Rock / Boise.

Snake river, celebration park-swan falls area.
