The trek up the stream took an hour or two, most of the way the scans didnt reveal anything new, until they reached the nearby foothills where the stream narrowed rising up to be sourced from a two foot high waterfall about 4 feet wide, the force though was considerable from the small hole in the ground from an underground source. Scans here showed concentrations of likely bacterial in nature, which seemed odd at first, since directly scanning the water showed they werent present from the hole in the ground, it was something nearby maybe? Perhaps looking around for something that might hide or conceal something could be the cause?

There wasnt much to look through really, there was a narrow dark ledge behind the waterfall that one would have to get on their hands and knees, and a bit wet too to scan through, another spot was in the stream or perhaps under the water bubbling up from something hidden in the waterbed or rocks in the stream. Not much else was really sourcing into the water otherwise.

“Hmm. Weird.” Usus said as he went into the stream to scan the underwater spot but only going far enough to not be carried away from the stream. Once he got close he pulled out his tricorder and started to scan.

Scans of the ground for the stream were clean so far, the water was fairly warm actually not too cold nor hot/warm. The hum of the tricorder as he walked about the water mostly up to the near top of his boots but not sloshing over them was a relief. Then as he got to a spot about just ahead of the waterfall near an off color brown rock the scans of purity and such seemed to go blank. As if something was blocking all scans within a 5 inch circular radius of the brownish rock.

Visually he would see the rock, but scans showed nothing was there, not even water. How curious!
