Where are the oil springs at Norris?

While the issue is up, it is worth noting that iron oxide minerals will also 
give water an oily sheen.  You can tell whether the sheen is really oil by 
dragging a twig across the surface of the water.  If the sheen breaks up into 
cakes, it is iron-based, but if it swirls around the twig without breaking up, 
it is oil.
