Great report, great photos. I was up there yesterday (july 3) though, and it's changed a lot. (I'd considered a few options and this was rising to the top of the list anyway, before this report. So my trip wasn't based on this trip report, although it did add some inspiration.)
It looks like this report only covers one bergshrund, there are really two. I'm guessing the first (lower) one was covered or bridged on June 27. It isn't now.
I got to the lip of the first bergshrund, which is about a foot or two wide with the lower side where you climbed up dropping off one way and holes in the sinking snowcover on the other. Even if you dared to cross the remaining snow the uphill side is a wall of ice.
This is typical, and usually the way around is on the left. But making an end-run on that side puts you under a rockfall path that is quite active right now. I witnessed quite a few rocks fly down that corridor, moving fast and bouncing. From fist size to torso size. I thought about it a little bit, but not too seriously given the risk, and then I went back down the glacier.
The right side of the lower bergshrund is a small icefall. If you could find a safe way to pass under it you could climb up the right margin but it's steep and exposed to some rockfall also, although not as active as the left end.
Just a heads up for anyone thinking about it. Glad you guys found it in the condition you did, it really is a great route. Perhaps one of the finest in the Oregon Cascades. It's often quite possible in the fall, around Sept. The rockfall you need to cross under becomes less active and the end-run is often more straightforward and therefore quicker. It's often necessary to then make an endrun around the right end of the upper schrund, which might involve weaving through some blocks of ice that sit above the little icefall.
