In Alaska ​ — which is called by some the world’s last frontier — ​ there are more than 60,000 native people living in over 150 remote communities, spread over almost 600,000 square miles [1,600,000 sq km] of wilderness, not connected by roads of any kind.
Alaskal — mida mõned nimetavad maailma kaugeks äärealaks — asub 1600000 ruutkilomeetrisel ühendusteedeta kõnnumaal ligikaudu 150 üksikut kogukonda rohkem kui 60000 põlisasukaga.
