Cal, someone moved that old trunk to block the bathroom door.

Also the trunk blocks the wind.

The wind grew stronger, though the trunk blocked most of it.

A trunk blocked the path ahead: they had to squeeze around it, only to encounter another in the way.

Ayla tried to see the way ahead, but huge, moss-covered trunks of trees blocked her view.

Moving only six inches to one side, I discovered that the trunk of the tree no longer blocked my vision.

So it felt as if you could see forever between the tree trunks, until finally enough trunks blocked the way or it grew dark and murky enough that you could no longer see beyond.

"The trunk blocks half our view," Harp said mildly.
