Anyone seen yeast finish like this?

My yeast cake looks like a moonscape! Used danstar Nottingham on NB's nut brown porter. 1st one I've had turn out looking like this.. Any ideas or is this the norm..

My guess: escaping co2 created bubbles/craters. Looks like a good compact yeast cake to me.

Absolutely normal

NO WAY THAT'S NORMAL!

The only time I've had that was an infection that got out of control. It ate my wife, God rest her soul. BLEACH THAT CARBOY NOW!!!!!!!!
