The Hamma Hamma road is in great shape right up to the washout at 10 miles. I parked there with about 12 other vehicles, and hiked the road to the trailhead (about 4 miles). My curiosity was piqued by a lone set of tire tracks on the road, and sure enough, at the Putvin Trail Parking lot (about 2 miles beyond the washout) there was a Mazda SE-5 pickup with high traction tires and a fair amount of clearance underneath. It would appear that with some vehicles, drivers can get through. But with the vigorous flow through the washout, there aren't any guarantees about getting the truck back down.
The walk on the road was great - with no vehicle traffic it's quiet, and the roadside vegetation gets a break from the usual summer dusting. Flowers were best along the road on this day - twin flower, daisies, paintbrush, foxglove, bunch berry, an orange lilly just getting ready to bloom, and many others I can't name without a handbook. The Hamma Hamma was roaring under the bridge at the road end, well worth the trip for the views up and down valley here. The four miles on the road took only an hour, so I had visions of a brief visit to the Lakes. Optimism waned at the register, where earlier hikers left sundry laments about losing the trail, bushwacking, landslides, and so on. In particular, none of the entries mentioned reaching the lakes. The first mile of the trail was just fine, same as in previous years, plus a couple of blow downs that were easily negotiated. Just beyond 1 mile, the trail disappears beneath a pile of downed trees that marks the edge of the landslide. I dropped down about 50 feet and found a place to work across the slide (about 60 yards wide) - this has to be done CAREFULLY because the trees that make up the ""surface"" of the slide are in many cases balanced precariously so it would be easy to break an ankle or worse in here. The pile of trees is insulating the snow underneath, and there's no telling what kind of problem the hiker might fall into when this snow starts to give under the weight. On the far side of the slide I lost the trail due to snow cover. Met another party descending the snow gully above the slide - they had reached the ridge, located the trail there and descended to the creek crossing near the 2.5 mile mark. They reported snow all over the trail down to the creek, high water in the creek, and no ""safe"" log for getting across. Since I was on my own, and they were the last party coming out, I decided to turn around rather than risk a tumble into the creek with nobody around to help. The return trip on the road was pleasant, though, with more flower viewing and great vistas of Mt. Bretherton.
