On January 31, 2000, the historic Mapes Hotel in Reno was imploded by 75 pounds of explosives tucked into the art-deco structures support columns. The destruction of the Mapes put an end to years of efforts to preserve the building via lawsuits, redevelopment proposals, and grass roots action. The National Trust for Historic Preservation took up the cause of the Mapes, and challenged the destruction in a suit that eventually reached the Nevada Supreme Court.
