ravenest, you have unique crystals and rocks. I wish I could see them, and feel their energy.
I will try some words for you then.
The river rocks come from the nearby river which is an old fault line. The valley was formed 100's of millions of years ago when two geological beds began pushing together ... this was when this location was over the south pole and 'proto-Australia' was forming into Gondwanaland. The southern bed slipped under the northern and pushed the northern bed up to form an undersea escarpment, lava intrusions as granite dome mountains and other intrusions. As time passes the coastal shelf and the sea level rises and falls, glaciers alternate with volcanoes on the growing (now moved to the) east coastal area.
Eventually the valley rises out of the sea, the coast is extended, erosion defines the valley. 56 million years ago a volcanoe erupts and covers the whole area in a large cone of various ... stuff. Erosion again and eventually the present valley.
So when you walk along this river bed you can see and be in this ancient fault and to the north the escarpment still looms overhead.
I found part of the bed rock with a riverstone embedded in it. I showed a geologist and he explained that long ago the rock was eroded, a riverstone formed, got picked up by a glacier, carried out to sea, melted and dropped rock on the old ocean floor ... the process above happened and there it is (he said pointing at the rock). A whole double cycle.
Then I found a riverstone with another riverstone welded inside it; a triple cycle 'about'
to happen!
It's just an interesting looking rock, but if you hold it and feel it, that is the energy and history it contains.
I like the ones where you can see the now set, boiling swirls and embedded crystals and minerals holding their story of a furious volcanic sulpherno.
