Take a look at boat peekchure sets... that will give you a good idea.
Z Perret showed some good ones already. Expect that-ish.
You should be able to work your way around Gem and the others you'll just
have to ziggy thru. If it's suncup heaven then it's slow going... but safe.
To help a bit more perhaps... here's what I'd expect Koip to look like...
Algers is in the foreground...

Again, stickler MAY be Gem..
Look at Perrets again... and then this is what it looked like for us:

I started going straight thru this... postholed thru... and started sliding down a bit... so we went down further ...
we brought kahtoolas... but those were pretty useless.... crampons they are not...
here's after we got thru it:

iirc there are 2 trails N of Gem which the pix are... one which works around the snow field which can persist longer
So... my 2 dollars worth is simply to hike up Lyell... go up to Donahue... if you hate it... then simply turn around and
camp in upper Lyell and explore... (you do NOT have to exit the TH that it says on your permit.. )
Or just grin and bear it... and get over Donahue entirely and go explore 1000, etc. That will be pretty free from what
I've seen so far. The snow can be a lot of fun... It's actually better if there is a LOT more snow ...
less snow that gets all suncupped and you sink a foot or more... not so great.
Have fun whatever u do
