In terms of Sage One (do not archive), the encasement for the ammo can is in the ground at the base of a sagebrush , however the ammo can it self is not "buried", it is simply placed inside the encasement. It is a very clever hide and really the least intrusive way to hide an ammo can based on my experiences..... this hide in my opinion does not qualify has "buried" at all. Nothing gets disturbed when retrieving and returning this cache, unlike when you see them placed in "rock piles" and bushes and other plant life...over time the plants get trashed, and the rocks piles are rearranged.
In terms of rules/guidelines.... I think it depends on the reviewer and if he/she decides to "follow them", in short...I notified our local reviewer of a cache on private property,,,,cache was archived...Okay....a few years later a local cacher unknowingly placed a new cache in the same area ... cache gets approved...I notified the cache owner and reviewer of all private property info... property owners, plot maps, etc. cache archived......
then interestingly enough a few months later the "SAME" reviewer "approves " the original cache under a "new owners name" in the same area and yes on private property. It sits there to this day"ready for the hunt." Yes even "marked" as private property as well.
Still looking for the "common Sense" in that one....
So I raise my hands and say.. Guidelines, what guidelines....
Funny because I am from the same area and so have the same reviewer...
Not trying to start trouble, but this has been my experience.
