The cache is located on the Glendale side of the fence, not the QEW side. It is a park and grab with a little bit of a bushwack. There is a clump of trees you have to enter - I entered from the western side. Parking is at the end of the traffic circle.
The cache is a small camo'd container with a log. There is room for travel bugs, etc.
I was working nearby and discovered an opening on my map just calling for a cache so here it is!
