On Wednesday Dhana and I went to explore some old gold diggings - I had a particular task in mind. I got very interested in the erosional and depositional history, and I wanted to look for evidence of erosion by moving water prior to deposition of the gravels. We went along the south / west side of the Clutha and snuck onto some land there are some old gold workings.
|View across Clutha River towards Graveyard Gully. It|
looked menacing all day but never rained.
Then we went further down the Clutha River and went up a small creek to another old mine / working (Ketts Mine). Always amazing how much work they did. We poked around there looking at stuff for an hour or so.

piled along the walls of the tail-race
In the afternoon we went just across the Manuherikea river so I could collect some good conglomerate samples for the SCSU teaching collection - BUT it is also a conglomerate that contains gold in the basal unit. so we spent quite a while collecting samples. When we got back, we crushed the samples, and then panned them - I got a few flecks of gold, but no nuggets. Rats.
