  The past year has seen an explosion of new and old ideas about black hole
physics. Prior to the firewall paper, the dominant picture was the thermofield
model apparently implied by ADS/CFT duality\cite{mal2}. While some seek a
narrow responce to Almheiri, Marolf, Polchinski, and Sully,(AMPS)\cite{amps},
there are a number of competing models. One problem in the field is the
ambiguity of the competing proposals. Some are equivalent while others
incompatible. This paper will attempt to define and classify a few models
representative of the current discussions.
