Pérangan paling enom saka pagunungan Rocky kaangkat nalika jaman pungkasan Cretaceous (140 juta-65 juta taun sing kapungkur), sanadyan sapérangan pagunungan sisih kidul kaangkat ing jaman Precambrian (3.980 juta-600 juta taun sing kapungkur). Kondisi géologiné kapethak saka kompleks watu beku lan watu metamorf; sing paling enom ya iku watu sedimen (mapan ing dawané bates kidul pagunungan Rocky), lan watu vulkanik saka jaman Tersier (65 juta-1.8 yuta taun kapungkur) mapan ing laladan Pegunugan San Juan lan ing sapropirané laladan liyané.
