I rode a bike to the new bridge across Lindsey Creek and went up Lindsey Creek a bit and made a beeline for the powerline road that took me to my first destination:
Summit Creek Falls on the northeast side of Shellrock Mtn

I stayed away from construction but I will watch with interest how access will be provided to the wagon road and the usable parts of trail up Shellrock. The viaducts being constructed are very impressive structures and I look forward to the completion of this project.
I crossed Summit Creek in a spot covered with downed red cedars but as bad as it looked, getting across was easy. There is access to the top of the falls for the brave/foolish.
There is a benchmark called Backbone that I thought I'd visit, worth it. The way there is easy as pretty much everything was burned away.
Way there:

Looking out towards the end, I see how it was named, it is a narrow ridgelet. Views are nice.

From the Backbone I could see the parking lot at Starvation Creek where I was parked. For X-mas I got myself a Nikon P1000 that has a 125x zoom, this is from ~2 miles away - a little blurry:

From there I hopped over the saddle to the west and joined the existing trail coming up from I-84. This part is in good shape and I was hoping that the rest might be like this, but no.
The lines of the many switchbacks are visible down to I-84.

Once at the top of the boulder field, the trail used to dive into the forest; gone, all gone. I'm pretty sure the trail ran along here.

Here is a short segment of existing tread about 50-100 feet from the weather station. Here there is blowdown to negotiate so what trail that does exist isn't useful.

The frame and the 'Danger' sign are still there, views are not bad but not worth the pain of getting there. Like 2 feet forward and 1 foot back on a severely unstable steep slope.

Steep slopes, loose rock and soil and not much to hang on to like this:

Beyond the weather station the situation improves considerably, still no useful tread.

The summit, no cairn, no views, kind of anti-climatic but in the original plan this was not a stopping point - the plan was to go south and return on Lindsey Ridge but it took too long to get to the summit to proceed so I went back the way I came.

The parts that were miserable on the way up were as miserable on the way down - I actually down climbed a lot of it.
Here are my meanderings of both Lindsey Ridge and Shellrock Mtn - eventually I'll put it together for the loop.
