kiwi jw said:Lanny, I ment to mention about those quartz rocks/boulders. Take a good close look at them. Go back to my earlier pics & Wildcats & the one with the gold I found sitting on one of those rocks. They are smooth. There isnt a sharp edge on any of them. They have all been rounded off. Look at the one that I show that has been turned over. The one where the hole from it is where I got the 4.5 grammer. Take a look at the rocks that you can see sitting deep in the ground with just their tops flush with the ground surface. They are smooth & as rounded off as can be. That is from ice grinding over them. Look at the scenery pics of the mountains. They are all very smooth from glaciation & not rugged & jagged from faulting & folding of which they would have been before the glaciation. Here is a pic of the Remarkables Range in Queenstown in the back ground. The tops were above the ice during glaciation but notice how smooth & ground off the tops of the other hill are in the foreground. This was totaly ridden over by ice. You will see the left hand side of the hill where the bed rock has been ground smooth & groves ground into it. Probably by big boulders caught up in the glacial ice like giant sand paper grinding over it & scouring it out.
Yes--thanks--I now see what you're talking about. The edges are rounded, and from glacial action--much like the rocks I see very close to the mountains--chunks of bedrock that is, that have been tumbled by glacial/glacial stream action. I guess I've been referring to two different things. What I generally refer to as glaciated rocks are the ones that have been tumbled to such an extent that they are "round" or oblong and rounded--you can't find an angle on them anywhere. But, now that I understand that we're talking about the same action that rounds off sharp corners on pieces of bedrock and stone, I understand what you're saying.
I'll see if I can dig up some pictures of glaciated rock from this area. Beautiful pictures of your mountains and the glaciated areas--and the live glacier!
Thanks again, and all the best,
Lanny
