Blankenship Bridge — Just upstream of the bridge on river-left is the formal river access. County non-fee campground on opposite bank. WATCH the bridge pylons — wrap potential. Reachable from Highway 2 above Coram.

Take-out

Teakettle (Columbia Falls) — FWP access below the Highway 2 bridge on river-right. Nice boat launch.
