The tallest mountain-peak you've ever set your eyes on; the shortest bonsai-tree you've ever gotten your hands around - just by themselves, it is very difficult, to convey, in a photograph, what makes them stand-out: their Scale.
To accentuate anything that's extraordinarily different in your subject - its largeness, smallness, or vastness, you can place a counter-point that's the opposite of your subject's scale, in your frame.
And if you can bring in a human element to make this contrast, that's even better!
With this type of juxtaposition, you can underscore your subject's impact quite effectively.
Happy Photographing!!
