[Cob] Clay discussion

[dan Burbank]

I live on top of a Puget Sound glacial moraine. No clay to be found for
miles and miles. I considered for a while to haul from one of the river
valleys either in my pickup or buying it from a contractor who is
building. BUT...

I am having a difficult time justifying the carbon expense of it. Just a
thought. Any time I build anything I will have to justify the carbon cost,
short of filled bag construction, which is currently the leader in my
thoughts of building a large protection wall around by new berry bed.

I would be interested in any thoughts. Not just about what I am working
on, but the philosophy of using what you have rather then moving materials
like this. I hope this is not asking for trouble in a off topic discussion
but not all of us are "blessed" with clay. Though I know gardeners who
would take issue with clay being a blessing.
