Dark, squarish non-aerodynamic object floating at high altitude from south to north.

I initially saw the object from the driver's side of my car as I approached my house. After parking my car, I went immediately to our south facing outside deck.

The object was dark in apparent color and in my initial view of it seemed to be squarish in shape. It had caught my attention because it definitely was not a powered airplane or helicopter and made no noise. I've lived in our house for 17 yrs. and am used to seeing and hearing aircraft flying over from the south towards PDX.

There was cloud cover (elevation of which I have not yet been able to confirm) and the object appeared to be at least 2,500 ft. in altitude.

As for it being an ultra-light or a powered or unpowered hang-glider, it did not to my naked eye appear to have any sort of aerodynamic shape. It was slowly moving from south to north and it seemed to almost be tumbling or rotating through the air and in so doing presenting different shape and outline profiles.

I will supply some sketches as a supplement to this text.
