So of course the common standard for proper burying of solid human waste is burial in a cat-hole, and generally this means one hole per instance per person. This is what I practice and teach on personal and group trips, per LNT guidelines.
But in what instance is using one large, group hole (latrine style), an appropriate and practical option? In other words, what situations make a latrine hole a preferable option to the standard cat-hole practice?
Of course it would be covered up, but only after moving on from that campsite. This sounds pretty gross to be honest, but I've known of some people who practice this in some locations.
