Patch on ground drops me out of stealth?

I found a patch of ground that took me out of stealth the 4 times I tested it out. This link is to a video showing the stealth loss occurring twice. I forget the keep name, but those in the know I hope recognize the site.

No resistance from keep, no detectable damage from treb (or damage from anything else I was aware of). I was cycling between treb each time I crossed the spot as I was on the look out for trouble.

I had dropped out of stealth two additional times prior to becoming aware of the spot; I repeated it four times to make sure I was not taking any damage or NPC were no messing with my stealth.
