Is there quicksand on mars?

I proposed this before, last year,
the old Russian sonde transmitted only for a very short time...
Things land but no signal.
Could there be a thin frosted layer that a lander would sink through
within minutes?
Again I als want to point out AGAIN that it is cheaper to
not send a lander then one that does not transmit data when landing.
In both cases you learn / know nothing.

Maybe we will have to wait for a nuclear powered lander that can hoover
and move to a suitable site.
Will perhaps be cheaper in the end.
