2000 Pathfinder coolant leak

With a mirror and flashlight it looks to be coming from the right rear bank next to firewall.
Could this be a head gasket? Or is there something else back there leaking other than a head gasket? Looks to be something bolted to the head. I need a parts breakdown or picture to show me what this may be. All the pictures of the head I have found do not give enough detail. Thanks
