Columbia River, Cathlamet, WA

I'm not really sure what these poles were once a part of but it looks like it may have been a dock at one time. Behind me are a couple of concrete pools, inside a secure fenced area, that look like part of a water treatment system, but this area had no signs to explain what I was seeing. This is the north bank (Washington side) of the Columbia River, looking west around sunset. To get here I followed a path behind the Wahkikum County Museum, down to the waterfront and around those large pools.
