The beavers had begin construction of another dam somewhere on Spring Creek. I didn't see the dam, but I saw the cylindrical gnawing on the juvenile tulip poplars, exposing their bare orange cores to the bare colorless winter winds. It resembled a cake, a baked orange-yellow warm center showing itself broadside underneath the coating of icing sugar that covers all tulip trees. I was catching brown trout underneath a dam, not one build by beavers but one constructed much more permanently with hands instead of teeth and stone instead of wood. I've read somewhere that the soft whisper of running water shrieks like nails on a chalkboard when falling upon beaver ears, and so they desperately plug it up with any available organic matter within a tooth or tail's reach, anything to make it stop. Are we like that as well? Our race of dam builders? I've always loved the sound of running water, heard it inland miles away when I close my eyes and drift through hallways facing upstream like a trout in a riffle. I suppose they hear nothing BUT running water. I don't think our species is like that. I don't thing we process beauty or pain very well in the moment, not until long after it's gone. When the Klamath River fell and Celilo Falls was buried in silence, it was done so without a second thought, until the deed was already done. I think my theory was corroborated in iron when at my next fishing spot, a set of railroads slashed deep along the banks of the creek, rails built to carry coal out of the hills, now enjoying very little use with no one to dig and no one to sit in the conductor's chair. The beavers are still here though, provided they last the winter. I think they will. Upstream facers tend to do well.
