GSA – Portland Building Stone Update


A quick follow up to my pre-GSA Portland building stone blog. Here are a few more photos of the First Congregation Church. It is a quite handsome building. I have no idea where the stone for the columns comes from but it beautifully complements the sandstone.

Unfortunately, one of the structures I mentioned in my previous post is no longer there. The Belgium basalt cobble wall is gone, replaced by an ugly cinder block wall. Apparently the wall had cracked and become “dangerous.” I won’t add to the ugliness by posting a photo.

In contrast, I did stop by the historic central library for Multnomah County (SW 10th Ave. and SW Yamhill St.) Opened in 1917, it is a brick building with highlights of Salem Limestone. It is very rich in fossils, which stand out in places where the softer, surrounding matrix has weathered and eroded more. Plus, I was quite taken with this panel of names. A rather nice cast of scientific characters.

And finally, I also found another Morton Gneiss building, on the south side of Burnside between NW 9th and NW 8th Avenue (just a block away from Powells). Again, the building is architecturally uninspired but with gorgeous stone. This time, however, the builders chose to use a white marble with black streaks instead of limestone. I suspect it is a Vermont marble. That’s all for now.
