This very short paper resolves the matter of black hole firewalls by computing the approximate temperature of a Planck mass black hole.  Based on previously published work on black hole temperature I present a precise prediction of the temperature of the Hawking radiation in this situation. The quantum that collapses into the black hole experiences a temperature of 1.410 septillion Kelvin.  This high temperature would last for about one Planck time. This certainly qualifies as a firewall.
