a A simplified cartoon illustrating of the modes of heat transfer from the deposit after emplacement. While radiation, atmospheric convection, and conduction all contribute to cooling the deposit, conduction is likely rate limiting in the days to weeks post-emplacement (Wallace et al. 2003). b A simplified cartoon representing two possible modes of deformation: lateral extension and sedimentary compaction. The observed subsidence and lack of strong evidence to support deposit slumping or creep leads us to favor contraction or shrinkage by deaeration and compaction for the formation of the fracture network
