<p>EK, thanks so much for that link to the article about the canyon restoration. I hadn’t read it before my previous post. Now I understand better what’s going on.</p>
<p>BTW/ I miss that pool. Not that I ever swam in it, but the amphitheatre above it was always a nice place to be.</p>
<p>I think in Portland moss grows on anything that isn’t moving.</p>
