Main challenges
- Hard winters — average lows under 15 °F in Dec–Jan
- Dry climate — only 14 in of rain — irrigated pasture or year-round hay
- Low selenium — regional soils and hay tend to be selenium-deficient
Advantages
- Summers rarely reach heat-stress levels for alpacas
- Short or no barber pole worm transmission season
- Low meningeal worm risk
Overall rating: 94/100 — Excellent on our alpaca climate comfort score. Climate type: Warm-summer humid continental (Köppen Dfb).

- Freezing nights: Nov–Apr — keep water from freezing.
- Vitamin D for crias: Oct–Mar.
- Grazing season: May–Jun, Sep–Oct (about 4 months); feed hay the rest of the year.
