I'm doing some gardening in my house! And I'm thinking about soil and vegetation, just like during my PhD.
The soil in the area is bad, poor impermeable glacial till. But above it there's some better soil. Trees, however, don't seem to mind the poor underlaying. I don't know if it's because they have shallow root systems, or because they can get nutrients from the organic poor but mineral rich soil.
I'll keep thinking about this in the months to follow.
I'll also will be posting more photos of this, and of buildings of Seattle.
Peace,
