((Possible defenses could be anything from snipers and spotters to holocams, etc...however, you've seen nothing at this point.))
Climbing up, Devlin finds a good spot with a wide view of the canyon path only a few meters up. The ledge isn't all the way up, but its protected while still giving a very good sight of the area. From the looks of it this small path in the canyon goes on straight ahead for a good distance, though it winds slightly here and there, you still have a very good view of the area. As far as you can tell...there doesn't seem to be anything there, though you do notice that from this height, the ground looks oddly well crafted into a nice, almost even path.
Sri, however, has trouble getting up. He manages to get about a meter up before he has trouble finding footholds, and slips down back to the rocky ground below. Thankfully, he lands on his feet and not on his backside.
The others on the ground move forward, finding that, while the path in the canyon seems to go on in a back and forth, winding way, there is actually an almost flat portion of lightly coloured sand at your feet that goes straight through. Whether this has been created by sentient beings, animals, or just plain coincidence, the fact still stands that it looks and feels like a dirt road of sorts. Still, though, you see nothing...but according to the sensor readings now on your datapad, the source is still there, and could just be out of sight.
