The Fly Geyser in Nevada resulted from an accident. Well drillers hoping to turn desert into farmland hit a pocket of geothermal water in 1916. Then, in the 1960s, boiling water found a weak spot in the well's wall and began spewing up. The buildup of minerals has turned the geyser into a bulbous, bubbling thing that doesn't look natural at all. Mariah Garnett filmed it as part of her new video work, Signal. She also enlisted Craigslist actors, two of whom aspire to narrate PBS documentaries, to stand on rocks on the Paiute Indian Reservation and read from her carefully edited archive of spam emails. So you'll hear actors reciting amazing lines like “You will drill her as good as Michael Phelps swims” for a while, then you'll watch the geyser aggressively spew. Signal plays in the back room at ltd los angeles, as part of Garnett and Anton Lieberman's show “Common Era.” 7561 W. Sunset Blvd.; through Oct. 13. (323) 378-6842,
