High Peaks area

This view is along the upper Condor Gulch Trail. Note the boundary between pinnacles-style outcrops on the left and forested slopes on the right. The rocks on opposite sidse of this boundary are reacting differently to physical and chemical erosion and weathering processes. Geologists look for such transitional boundaries. They may represent faults, changes in geologic strata, boundaries of igneous intrusions, or other features.
