Back to the invented Kestrel Creek sheet. Tilted layers, a flat ignimbrite on top, and a fault that does not cut it. In what order did all this happen, and could that fault carry hot water? By the end, you can put the events on a map in order, name the fault type, and say what faults can mean for hot water.
