Rc 4x4 with go pro cam and live gps feed. That way you map it out on gps and get recording of the tunnels. I would recommend using a smaller electric rc truck like a rustler. You want big enough to get over small objects and small enough to avoid anyone in there by out maneuvering and out Speeding them. That's a worse case scenario though. The rustler is big enough to mount everything necessary without its speed and manuerving impeeded. Keep the shell off the frame and go with a go pro and live Gps feed and your golden. You'll have video of the tunnels and a mapped out tunnel to match the video. Only thing I can say is good luck finding the tunnels without getting into serious shit first.
GPS usually doesn't work well underground. You don't get good enough reception. To the point where Verizon and Ford have worked on ways to get the signal underground (which require antennas that transmit the signal): https://www.telogis.com/blog/how-to-get-gps-tracking-working-underground

That's over three miles from Comet.

Yes it is. Seems VERY unlikely it connects to Comet, or anything on the other side of Rock Creek.
