Recent experiments demonstrate how dissolution, in conjunction with gravitationally-induced convective flows, can create sharp geometric features. These laboratory-created structures give insight into geological features known as karst pinnacles. A new computational approach, specially tailored to the hyberbolic nature of the underlying PDEs, reveals convergence to a morphological attractor with high, yet finite, tip curvature. These results reverse previous hypotheses on shock formation (i.e. finite-time blowup of tip curvature), agree well with laboratory experiments, and enable simple estimates for the age of geological structures.
