By now he is bugging me so I got into a pretty deep discussion about intelligent versus a repetitive haunt and how they ought to not care about time.
This issue that Terro brought up, on whether there is an repetitive pattern or a random pattern to paranormal activity is very interesting. It is not clear to me whether we can deduct intelligence from cyclic or random pattern.
If a pattern is random, it could be due to natural random patterns (either geologic, atmospheric, or other) or it could due to a deceptive move from an intelligent agent.
If a pattern is cyclical, it could be due to natural cyclical patterns (seasons, weather, solar flares, moon cycle, etc.) or it could due to an intelligent agent's recurring visits (portal opening or other speculative reasons).
With regard to the Skinwalker Ranch, I have seen no good database or statistics on patterns (with time, date). I hear or read about many anecdotal stories but see nobody looking for patterns. I wish either Hero or Skinwalker started a database. I am excluding the database that Salisbury included in his book, because it is dated and did not focus on the SWR. In addition, if NIDS has a good database, they are not sharing.
You can eliminate hypotheses on whether the balls of light or "firework" lights seen are correlated with earthquakes, moon cycles, solar flares, etc. only after you have a database that disproves them.
If you find cyclicality in the data (either with time, season, moon, solar flares, or whatever), then you can use this to predict next sighting and be prepared to document.
Even if the source ends up being some unknown intelligent agent that is intentionally playing tricks, I still believe we should better document the time, date, and location. At least this would help establish the boundaries of the phenomenon. Right now, it is not clear what is the range covered by the Skinwalker Ranch phenomena. Is it the whole Uintah Basin? Is it the SW Ranch plus a radius of X miles? Does it include the high Uintah Mountains? Does it include Vernal? Etc. Etc.
