Here is an interesting post over at the Bedrock Dreams blog. While it is focussing on working dry gullies, it is obviously relevant to the kind of gravel bar locations we commonly work with our high bankers.
Basically, he recommends getting down to the bed rock or clay layers where the chunkier bits accumulate. Problem is, we don't have X-ray vision to easily find those spots where this material is only a foot or two under the gravel.
Anyway, I'm just throwing the link out there for consideration and discussion. At the time of posting this Jim only has part 1 up, but the next instalment should appear soon.
