Bhala iphuzu lokugcina izindawo zomphakathi ngaphansi kokulawulwa yi-federal e-Intermountain West.
Izindawo zomphakathi ziyingxenye enkulu yesifunda esiphakathi kweSierra Nevada neContinental Divide eRocky Mountains, eyaziwa nangokuthi i-Intermountain West, futhi iningi lalezi zindawo liphethwe uhulumeni Wombuso. Izakhamuzi eziningi zalesi sifunda esinabantu abambalwa ziyakwenyanya ukulawulwa kwalezi zindawo izikhulu zikahulumeni eziqhelile ezinemithetho ebeka imingcele ebalulekile endleleni umhlaba osetshenziswa ngayo. Ngenxa yalesi sizathu, sekuyiminyaka eminingi kuqhubeka ukunyakaza ukuze kudluliselwe lezo zindawo kuziphathimandla zendawo. Nakuba lo muzwa wokuncishwa amalungelo uqondakala, iqiniso liwukuthi izakhamuzi zasendaweni zizohlupheka kakhulu ngokulahlekelwa ukuphathwa kwalezi zindawo ngendlela ehlelekile kunokuba zizothola ngokulawula kwendawo. Lesi sifunda simagwadule kakhulu, siyisimo sezwe nesemvelo esithinteka kalula uma siwohloka. Ngaphandle kwemizamo ebumbene yomnyango ongasebenzisa ukulawulwa okuhambisanayo nokuphathwa kwalezi zindawo endaweni ebanzi ewela imingcele yombuso, ukubaluleka kwalezi zindawo kubahlali bendawo bekuyoncipha nakakhulu, kube okungabi nakhiqiza kangako futhi kungabi kukhanga kangako kubazingeli, abadobi, nakwezinye izivakashi ezikhokhela ingxenye enkulu yemali engenayo yalezi zindawo ezisezintabeni.
