Taken at Mabel Downs Station campground at Purnululu in the Kimberley, Western Australia during our trip there last year - 8 minutes after my earlier posting Boab at Dusk http://365project.org/terryliv/from-the-archiv/2014-07-09
@richardhoeg The Boab stores water during the wet season for use during the dry so I would imagine it is related to that. @corymbia is the best person to ask.
