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.
