Walking into the closed-for-the-season Central City Opera House, Lisa Zetah's breath turns visible in the chilly air. It's easily at least 15 degrees colder than the temperature outside.
"That's because a creek runs through it," explained Zetah, who's with the Central City Opera Association.
The Eureka Creek runs right under the opera house, she said. When it was built, a wooden flume was placed over the creek and the building was constructed on top.
