Well, i thought a little about it (30s). On the common trails they all use and pee on, say the extra stuff gets trapped under the layers, adds some slush along the way. As they trop all over it back and forth, is there a chance it starts jiggling and sliding?
quick math tells me that if we include urea (0.85M) and salt (0.71M) then freezing point of urine should be about -4C, in close to worst case scenario, which decreases roughly linearly as it is diluted. meaning that this is temperature where urine starts freezing, but below that point there is some amount of liquid where all urea and salt concentrates. just for water-salt mix some amount of liquid will remain down to -22C
i guess this gets more important at higher tempetatures
I do no math, isn’t this about a lower freezing point for water due to the extra chemicals?
I believe that effect would be even less noticeable.

I can suspect a chance of yellowing, but that’s it :)
