How can I find what is feeding my 3850 switch stack?

I have a Cisco 3850 stack with dual 10G fiber feeds that aren't labeled. The trunk interfaces/port channel are not labeled either. How should I go about finding where these fibers go or what feeds it? If I can get any information on the device that's on the other side that would be a huge help.

sho cdp neighbor only returns a bunch of APs and IP phones; no switches or routers. The device on the other end is probably something Cisco but could also be Juniper. Any help is appreciated.

I've been googling but maybe I'm not educated enough to understand these articles I'm finding.
