Montana · Off-grid & homestead potential
Blaine County scores 46/100 on the Bolthole Index, a marginal county profile. Its strengths are deep seclusion — about 1 people within a 30-minute drive and manageable long-term carry cost. The trade-offs: weak self-sufficiency basics: only 14.4″ of rain a year and elevated current hazard exposure.
