在科罗拉多落基山国家公园大陆分水岭以东的每一个主要山谷中，都重复着类似的冰川地貌。的性格和分布格局的冰碛，梯田残留的山谷列车，和冰侵蚀的上谷形式的证据表明，冰川占据这些山谷至少在三个阶段。所有观测到的冰川地貌都位于发育良好的山谷中，没有证据表明冰川向东延伸到埃斯蒂斯公园。也没有发现任何证据表明，在落基山国家公园的北部和南部，在山谷间的高分水岭上发现了与草原分水岭和钨山（前威斯康星州）冰碛相对应的非常早期和广泛的冰川作用。
Within each of the major valleys east of the Continental Divide in Rocky Mountain National Park, Colorado, similar associations of glacial land forms are repeated. The character and pattern of distribution of moraines, terrace remnants of valley trains, and ice-eroded upper-valley forms are presented as evidence that glaciers occupied these valleys during at least three stages. All observed glacial land forms lie within well-developed valleys, and no evidence was found that glaciers had extended as far east as Estes Park. Nor was any evidence found of a very early and extensive glaciation corresponding to the Prairie Divide² and Tungsten Mountain (pre-Wisconsin) tills recognized on the high in-tervalley divides just north and south of Rocky Mountain National Park.
