I've used my Gorge for working with fire pits and cat holes more than anything else...there just isn't much other use for a shovel in the bush that I've found. 
Yeah, that's pretty much right; not too much use for a shovel in the back country if on foot.  Potty trowel is all I usually take.  Like having shovel in the trunk when driving on dirt roads or in snowy conditions.
I bought my Glock shovel 'cause I wanted to do trail maintenance.  The Forest Service hereabouts pretty much has abandoned regular trail maintenance.  It's pretty much left up to the locals to keep the trails alive.  I bought the Glock so I could easily hike it in to spots needing some work.
The only other thing I can see the Glock shovel being used for in the back country is for campsite leveling.  A lot of the time, tent sites lose their levelness due to erosion.  Nice sometimes to just level it out.
