Strange Maps has posted this map from Leslie's Weekly, drawn by H.M. Pettit. Its full title is:
Destruction of One of the Greatest Modern Cities. Bird's-Eye view of Stricken San Francisco, Showing the Burned District, Covering Twenty-Five Square Miles, With the Most Prominent Places and Buildings Carefully Indicated.
Pretty wild stuff. For an in-depth exploration of that disaster, we highly recommend Simon Winchester's A Crack in the Edge of the World, available as a book or audiobook. Damn--the hardback of his book is going for $7 at Amazon as I write this. Any book by Winchester is good for that matter.
