Are those on the map lol?
The top one (truck) - yes. It has been there for ?decades? (not marked on the original 1991 map, but it is on the 2006 major update).
The antlers - no. It looks they arrived there only this year or early last winter, and might not be there for a long time. there is still a bit of hair attached, and still a few flies hanging around (although maybe they were just the blackflies that were continually eating me). I am also not sure what colour they would be as a special feature they are not black (not manmade), not a blue one (not water), or green (vegetation), but could I suppose be considered brown (earth)? :)
Upper photo looks easy to map!
