I guessed a dip stick but as the sludge is very soft I doubted you would
be able to "feel" the transistion from water to sludge and anything
sticking to the stick would get washed off coming back up through the
water or wiped off on the crust.

Cloth on the end solves both of those. Not that I'm going out there
today, in the cold E'ly and blowing powder snow.
