Kondisi geologine kapethak saka kompleks watu beku lan watu metamorf ; sing paling enom ya iku watu sedimen (mapan ing dawane 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 sapropirane laladan liyane.
