I’m not clear why this image did not come up in earlier searches, but in digging around for images that might show Coolbrath’s dock, the following image turned up. It was taken by Robert H. Gay in 1910. Same fellow who took the image of the schooner at Norwood’s Wharf. Indeed, it was possibly taken on the same day or thereabouts and from roughly the same spot on the Norwood property.

It appears that our site is a lot more complicated than we realized.

The house we started with looks to be in the upper right. Clearly there is much, much more going on.
Wednesday is going to be quite a day.
