Abstract

Cavernous weathering may be conceptualized as a self-reinforcing process, characterized by positive feedback within the weathering system. A morphometric study of caverns in the Valley of Fire State Park, Nevada, demonstrates the applicability of a dynamically unstable, or conditionally unstable, model of cavernous weathering systems. A paradoxical relationship exists between the weathering system output at the scale of individual forms and the outcrop scale : caverns tend toward minimum interior surface area by developing a spheroidal form, yet the outcrop surface tends toward maximum exposed surface area by increasing the degree of fragmentation of the surface
