Tap ... When the charred remains of a hiker are found at Yellowstone's Solitary Geyser, no one wants to listen. Tap, tap ... When geologist Dr. Gary Hawkins presents unparalleled evidence to support the effects of fracking and earthquakes, no one wants to listen. Tap, crack... When the Old Faithful basin tries to warn with its largest earthquake ever and animals are fighting to escape, no one wants to listen. Instead, busloads of tourists arrive eager to capture Yellowstone's power. Only now the world's largest super volcano is cracking open, ready to show its power ... and it's too late to listen.
