Figure 8. Comparison of correlation schemes for the Front Range and Mosquito Range. The “traditional view” (e.g., Berg and Ross, 1959 ) correlates glauconitic and dolomitic deposits along the Front Range (Missouri Gulch, Williams Canyon, Deadman's Canyon) with the Peerless Formation whose type

locality, and localities are arranged from most proximal (Willow Creek; Figs 2 and 3 ) to most distal (Woodside Canyon No. 2; Figs 2 and 3 ). The stratigraphic position of each sandstone is shown in Figure 8a (Willow Creek), Figure 8b (Deadman Canyon), Figure 8c (Straight Canyon), Figure 9b
