Helix Spire by erich remash (www.helixspire.com)
I initially thought that this climbable art installation got set on fire prematurely by an act of vandalism.
But here is a comment from Erich, one of the artists about the burning:
For the sake of clarity, you should know that the Helix was "not" burned prematurely or by vandals. Although during the burn, enforcement did show up and imply as much. We did things by the book, had permission and DPW+FAST support. We didn't intend to burn the structure initially, we managed to work it out however, but the only available slot was Thursday night. In hindsight this was a bad decision on our part, we lost sight of how many people wouldn't even be on site until Friday. What can I say, It was my second year on the playa and my partner's first. Live and learn.
