Agreed - a nice map - especially helpful for those who have been there. Wikipedia suggests its area to be 325 Ha (800 acres) and elevation - 321 m (1053 feet). Google earth (or Google Maps) provides a distance scale on the applicable page - FWIW.
I've already had my 5c worth (or less) on the recovering of the deceased on the other coverage of this topic in JB (Also FWIW).
