Thanks for posting this.  The gate at 224/46 has been open for a while now, but last time I drove it (over a month ago), the gate on the far end was still closed, even though it was thru the fire area.  I'm interested to get back up 4635 again as well. 

Cache Meadow did not burn, however a relatively small portion of Rimrock burned.  I hiked Rimrock from the east end a while back and a small portion near the west end burned somehwat.  It isn't terribly bad though.

I also meant to ask how much snow was at Olallie?  The modeled snow depth maps still show a fair amount of snow at the lake and the road in (4220).  Maybe the models are wrong?  They aren't perfect but I've usually found them to be pretty good, usually erroring on the side of caution (meaning they might show a bit more snow than reality).

I had today off, so I decided to see if I could get up the 4635 road to hike the MP3 trail.  Good news!  I went up 57, then back down 4630 towards Harriet Lake.  They paved the road thru the lake area, which is really nice - keeps down the dust a lot.  I continued past Harriet Lake and got to the junction of 4630 and 4635 - the road was cut out about 5 miles up, but at that point there are some logs across the road, so the Cache Meadow/Upper Cripple Creek/West Rimrock trailheads are still not accessible.  I did cut out one log but then encountered the next blockage and since it was just me I turned around.  I was able to get to the MP3 trail with no issues.  On the way home I thought I'd roll the dice and see if I could come back pipeline road.  On the way in the gate at Three Lynx was open but there was a sign saying "gate closed" (which seemed a bit odd, but I figured it was a warning that the gate might close at any point).  I figured if the gate was closed I would just go back the way I came in.  I was able to drive all the way down pipeline road, thru what used to be Three Lynx and back onto 224.  They've cut out all the "hazard" trees on pipeline road, so I really don't understand why it is still closed.  There was also a gate on 4630 at the junction with 4635 but it was open as well.

Things look quite a bit different than they used to on pipeline road.  Unfortunately, it doesn't appear they've fixed the trailhead for the Cripple Creek trail next to the pipeline above Three Lynx.  The trail got pretty much obliterated up to the first switchback after they cut the road out.  The sign that was there is gone as well - I'm wondering if the Forest Service is just going to abandon the trail.  That would be sad because that is/was a great way to get up into the snow in the winter.

The notice I saw said that the closures will be limited to 30 minutes or less - but going either Pipeline or 4631 seem like the best option.  I'm very sure you will be able to continue up to Shellrock/Hideaway/Rock Lakes on either of those roads.  I remember years ago when 57 was closed for a couple of years - 4631 was the bypass.

The work area is only within the burned area - I'm 99% positive of that.

Well, I guess it depends on which notice you read - I just saw this one which says they will only open the road 4 times a day during the week -

 Traffic will be allowed to pass through at 10 a.m., 1 p.m., and 3 p.m.

It starts next Monday, July 15th and will be from 7am - 5pm Monday - Friday.  Given that the notice is dated until Sept 1st, I'd guess they will be doing this for the next 2+ months.  The good news is that you can take 4631 to go around it.  It will be a bit dustier and slower but it should work fine.

FYI, I see I just posted the same link you did earlier.....  😳
