Cottonwood Canyon Road is a 47-mile dirt road whose clay surface, washes and drainage crossings can deteriorate rapidly with rain.
Wet weather can remove the practical State Route 12–US 89 connection and leave no reliable through passage.
Planning response: Check the current BLM road report and flash-flood forecast, and use the paved highway alternative whenever wet conditions or an unsuitable road classification is reported.
