In late 2013, Eichar completed the non-fiction book "Dead Mountain: The Untold True Story of the Dyatlov Pass Incident". Eichar came across the story of the Dyatlov Pass incident while carrying out research for an unrelated project. Eichar initially had plans to make a documentary but after traveling to Yekaterinburg for research he decided to author a book instead. After securing a book deal with Chronicle Books, Eichar made a second trip to the location of the incident in the Russian Ural Mountains, uncovering new evidence. The book is a reversed engineered investigation of the un-witnessed tragedy.
