Yes there are soffit vents. All of the tresses look like the one pictured. The roof is not very steep, it's a crouch-and-crawl at the highest point in the middle.
I just had insulation installed in my attic, and I was wondering if the picture I took looks like everything was done right. I'm in Minnesota. I guess I thought that there should be baffles between the tresses? If anyone knows, I would appreciate it. A photo is attached.
