text: two vertical tanks, one horizontal cylinder, and a number of other structures including a comms mast.
  
  easiest in clarity; no apparent changes since that decade-old aerials.
  
  don't see a clear rig shadow here.  pumping station?  too new to show on topo maps and no pipeline mapped in the area.
  
  go ahead and map as described, though i don't see clearly if one building may be just a roof.
  
  actually, that mast may be just a power pole.  would be nice to see the small items casting indistinct shadows at the north too.
