September through October is the cleanest production stretch statewide. Pre-winter residential rush concentrated September-October. First hard frost early-to-mid October northeastern, mid-to-late October southern and Black Hills.

Black Hills ponderosa pine produces a moderate-density spring-pollen wave in the western corridor. Wet-only handling. No scraping, no dry-brushing. Pattern operationally similar to what Easton Giordano documents for the northern New Mexico mountain corridor.
Statewide hail-storm exposure heavy. Wind-driven debris pattern, hail-impact residue, occasional structural-residue from damaged adjacent properties. Recurring post-event cleaning surge through the working season.
