Showing the description for the term identified by the argument in the Taxonomy Term view I have a view that is a clone of the Taxonomy Terms default view, it has the depth modifier turned on.  I would like to provide the description field for the taxonomy that has been loaded in the header if it exists.  I'm using this with pathauto, so while the actual url may be something like /pub/by/geo-area/ethiopia, views gets the tid (lets say 3046) as the argument.

How can I then put the description field from that taxonomy term into the header of the view?  I tried creating a relationship for the taxonomy term content, but since I don't know at the time of creating the view what vocabulary the term will be from, and because it is possible that there will be multiple terms for that vocabulary attached to some of the nodes, that doesn't seem to be workable.

I considered an attachment, but I'm not sure how I could pull that off either.  Can I do this without an extra module?
I want the description for the term coming in via the contextual
  filter argument


Ok then, 

1) Create a new view


Show: Taxonomy Terms. 
☑ Create a Block


Display format: Unformated list of Fields



2) Save and Continue.


Add the Contextual Filter.
Add the description field.


3) Go back to your other view and attach view to header.
