How many guaranteed flaregun spawn locations?

[piddy3825]

I can always find a flare gun in the tram car at the bottom of Raven's Ravine, at the top of the stairs of the old lighthouse in Bleak Inlet and of course in the tail wreckage at the top of the summit on TimberWolf Mountain.  I've always been able to locate these three in particular, but then I've also found one once somewhere in either Hushed River Valley or Ash Canyon.  I don't recall which it was however.  Now I'm curious if there is a flaregun in BlackRock as well?  Maybe bringing the total flaregun spawning locations to 6?  

Are the afore mentioned three always guaranteed to spawn and others maybe not? 
Any help and clarification would be very much appreciated, particularly if you can help pinpoint location!

I'm not 100% sure if they're guaranteed but I have found those three on every run so I would presume so... the one in keepers north has also been there on all my .runs.

I believe the Hushed River Flaregun can spawn in either Peak Cave, Valley Cave, or Lonely Cave, and exactly one will spawn per playthrough.

Thanks for the heads up!  I just so happen to be in HRV so I'll be checking those areas for certain!
