Was lucky enough to summit on 6/12 in a brief weather window between high avy danger and deteriorating weather. The summit was socked in, but conditions were relatively clear and cool on most of the upper mountain.
A serac fall occurred on the DC route the day before the attempt before the start of the cleaver (Ingraham ice fall). Walking across a linear gouge in the snow in the am I though it was a crevasse and warned the climber behind me. On the way down in the light of day I could see it was a rivet gouged by an ice block that calved off the glacier a few hundred feet above. The section is visible in the photo below, taken from the flats camp.
The upper mountain above DC was highly variable. Lots of sastrugi and surface varied between 2 foot postholes to supportable crust, the latter being very efficient to move across.
The parallel group was turned around from my understanding due to concerns over descending the variable snow. They had a larger group and helped set the trail/wands up to the cleaver.
Weather set in gradually as we descended, offering a brief period of sun crossing the Cowlitz back to Muir, before turning into a PNW goretex eating downpour all the way from Muir to Paradise. I suppose that was the mountain's way of reminding us how lucky we were to get that brief summit window.
