In this photo you can see many of the characteristics of Elm.
The pinkness of the cambium layer(oxidizes very quickly)
Stringiness
Scaliness of out bark( the edges of the scales get whitish too)
Heartwood color
Slippery appearance of the sap wood(outer bark peels VERY easily this time of year)
.....50 years experience
......... and the Elm leaves in the pic
OK, It's hard to beat experience. You have me completely convinced. It's not American Elm, neither is it Siberian Elm(Chinese), so it must be Slippery Elm?
We have none of it that I know of in this state. The wood looks just like the Siberian Elm, but the inner and outer bark is different. Leaves are also quite different.
I try to make a point to know what I am cutting, what I am working with and what is growing around me.
Very nice answer! You have spent a few days in the woods no doubt.
