Empire has unaccountably slipped up in not showing the base of the dolerite to be a target on the Bellevue hole section, don't you think? After all, everything else in sight from coal beds to oil shale units have been conscripted to be targets.
Your "pressure cooker" analogy is faulty but that's another story.
But the way I see the dolorite [sic] is just as a cap seal as to why they're are few shows and it as also a further pressure cooker. There is a few of them. Dang! A few of them? OMG, i'd just be happy w/ one good seal. But 100%?!
