As of 1:00pm on 12/3, the approach to Silverplume was frozen solid - crampons made the smoothest and quickest access to the base of the mainflow.
The Main flow presented 2 sections to climb in the WI3 range, and the WI2 gully to climber's-Right was also in great. We ventured up the cascade to find 2 additional flows in the WI2+ range that were also in descent shape.
Notes:
The (single) bolt used to rappel the (3rd) Upper flow is old and in poor condition.
The rocky terrain surround the flow is still not quite frozen into place - pretty loose in spots.
