In 2021, neighborhood historian Doug Decker, used pictures and maps to show the early days of Sullivan’s Gulch - both the neighborhood and and place itself. See the video, History of Sullivan's Gulch, at this the link.

Doug has now written up the information for a 4 part series on his website AlamedaHistory.org. He's included some new information and the old photographs and maps are available in higher resolution than on the video.

The panoramic photograph above is of NE Portland in 1903.  It was taken just before the Sullivan's Gulch and Irvington were developed.  The view is east-northeast.    It's part of a bigger panorama of Portland taken by courtesy of local historian Doug Decker.

First a little orientation: 
​

• Point 1 is Rocky Butte
• Point 2 is on the Alameda Ridge, with just a few structures on it — probably farms
• Point 3. This open area is farm land that was on a trajectory to be part of the broader Irvinginton development, but not yet subdivided on the ground. Doug Decker says,  it's bordered by today’s NE Thompson-Fremont between 7th and 15th.  This may have been used by the Multnomah Fair Association for various activities.

A higher resolution version of the image, without the circles, can be found here.  Smaller images of the full panorama are here.
