Hi Dan,
The short answer is "yes".

- on Mt Owen, looking NE - Aug 2011
However, it wouldn't be my choice of locations. It's very scrubby up on Mt Owen and, where there is an open patch, very rocky. Of course, up on top there is no water (other than rock-puddles after a recent rain).

- on Mt Owen, looking to Mt Nibelung and Monolith Valley - Aug 2011
Still, great views from the plateau - well worth the effort (even if you don't camp up there).
