I crossed these passes mid-August 2011. A bigger than average snow year, but nothing like this one, so my situation may not apply. Feather had a long Snow run from ~11,800 all the way to the pass. This year it may extend even further and you might hit snow shortly above Bearpaw Lake. Heading N to S, with microspikes, this was an enjoyable pass to cross. The snow allowed a straight line, talus free ascent.
White Bear pass had just a small snow cornice at the very top and a small snow field to the lake. We ascended at the left edge of the cornice and crossed the snowfield and then around the northeast end of the lake. Snow may extend further this year. Our crossing did not require microspikes. I think the biggest challenge this year, assuming a larger cornice, will be finding a path up either side. Once atop the pass, the “snowfield” has no appreciable slope. Puppet Pass was snow free, so no insight to offer for that crossing.
