However, it is a good point you are making here.  |
I'm no geologist by any means but I thought alpine glaciers produced "U" shaped valleys out of "V" shaped ones? Thats not to say the valleys in the Dividing Range are Glacial (they're not) -- but I thought a glacier converted the valley they were in from "V" to "U" via erosion?
Obviously we're talking about alpine glaciers here -- not the ice sheet variety (like Greenland) that cover a continent.
