Here are some links which might be helpful to determine if Santa Clarita is one of the known area's for seeps. Maybe someone here who knows this area can determine if Tony's bubblers are on the map.

McKittrick Tar Pits

The combined effects of heat and time slowly converted the soft parts of the diatoms into liquid oil. At the same time, movements along the San Andreas fault folded and cracked the Monterey and overlying rocks to create pathways along which the oil could migrate. Some of the oil became trapped beneath a cap of Monterey Shale that appears to have slid off the mountain sides of the adjacent Temblor Range in the distant geologic past. Most of the seeps at McKittrick are found where erosion has removed the Monterey cap rock and exposed porous and permeable sandstone beds of the underlying Tulare Formation.
