Prepper Assessment
Living in this area offers a mix of rugged terrain and a dry sub-humid climate, characterized by an annual mean temperature of 46.2°F and 19.3 inches of rainfall per year. The growing season, suitable for USDA zone 7a, allows for a variety of crops, although the water availability may be a limiting factor due to the area's classification. The remoteness, with a population density of 41.2 people per square mile, can provide a sense of solitude for those seeking a self-sufficient lifestyle.
However, there are notable risks to consider. The county ranks high for natural hazards, particularly wildfires and hail, both at FEMA rank 97. Additionally, winter weather poses significant challenges with a rank of 95, while lightning and cold waves also present concerns. The violence percentile is at 75, indicating higher-than-average violence in the area, which could impact overall safety. The median home price of $247,800 may also be a barrier for some prospective homesteaders.
This county may suit individuals who are well-prepared for harsh weather and have experience with agricultural practices in challenging climates. Those looking for a remote lifestyle with access to amenities in Rapid City may thrive here.
