Well yes, a large stump for a Redwood or something could work quite well for a landmark and control point support... but it may be... too recognizable. If we make specific landmarks, they are bound to be overused and noticed much more than all the other props in the theme. Plus it would likely mean for every control point placed on it to have height variation - although very slight, it could likely alter lots of things, and like the prop itself, be a repetitive gameplay usage of it.
