The Variable Darner is a large darner with narrow stripes. While some of these dragonflies have full, narrow stripes, some have the stripe divided or broken.
It is easy to see why it is so important to get the side view when photographing dragonflies. Without a look at the lateral thorax, it is virtually impossible to identify the different species.
There is a lot of variation between species and within species. For instance, a female Variable Darner can have blue eyes and a lot of blue on the body or it can have brown eyes with yellow body detail as shown here.
I found these near Windsor Lake where a ditch runs the length of the trail.
