Made first yeast starter last night got home today and this is the bottom of the flask. Is this normal?

Did you boil dme directly in the flask? If so, it might just be scorched dme. I don't know... never seen that in a starter before.

As long as you didn't overheat the yeast, a little scorch in the flask should be okay as long as you crash and decant as much of the liquid as possible prior to pitching so you don't carry over the flavor to your beer.

I wouldn't worry too much about how much yeast it "looks" like you have in there. If your process is sanitary and your temperatures aren't hot/cold enough to hurt the yeast then the reproduction of yeast should work out fine.

I'm over here now
I'd agree that looks like scorched DME. I can't imagine anything else taking hold that quickly. Is it on a stir plate? If so you really won't see the yeast settle out until you cold crash it.

Agreed. That's a fair amount of yeast for a 2L flask - a bunch actually
