I could be shot down in flames here, but may I venture from my uninformed perch in the bush that that that landmark is possibly a glass house mountain, being a singular of the famed plural Glass House Mountains???? perhaps. (Looks like one I saw up close anyhow)
By the way, I am very interested to know the cause of Old mates vibration which caused the forced landing.(I'm thinking maybe a lost prop tip, or maybe a blocked or broken injector line to fly it out so soon after). For sure he did a tremendous job to put it down in that area
