Scott, what a lovely tree, and pretty setting! The tree really makes a beautiful garden specimen tree. As to the very narrow crotch. Yup, I would be a little worried, due to the amount of rain you get in your area, as well as trapped water in that narrow crotch could freeze and expand, damaging that crotch. Don’t know how much of the canopy is part of the right big branch, but I would consider removing that right branch, as well as the skinny branch just below it. You probably would be sacrificing about 1/2 the tree, I fear.
Edit: Okay, boy. I am afraid at this point, I rescind my recommendation. I think it would just be such a huge wound to the tree, it may be just too drastic. I’m going to see what some of our more experienced orchardists have to say. I’ve done this to a tree or to of mine, so don’t feel too bad. It happens. We can’t get all the pruning right sometimes.
