The right lateral moraine was disturbed by a large tributary glacier that occupied the basin of Cascade Creek, causing considerable complication in its structure.

右侧冰碛被占据喀斯喀特溪盆地的大型支流冰川扰动， 导致其结构相当复杂。

A beautiful variety of the bench-top lakes occurs just where the great lateral moraines of the main glaciers have been shoved forward in outswelling concentric rings by small residual tributary glaciers.

就在主要冰川的巨大侧冰碛被小的残留支流冰川向前推成膨胀的同心环的地方，出现了各种各样的台顶湖泊。

The latter, on account of the uniformity and continuity of their protecting shadows, formed moraines of considerable length and regularity that are liable to be mistaken for portions of the left lateral of the Tuolumne tributary glacier.

后者由于其保护阴影的均匀性和连续性，形成了相当长且规则的冰碛，容易被误认为是 Tuolumne 支流冰川左侧部分。

Stream sections show the gravel deposit to be composed of the same material as the moraines, but finer, and more water-worn from the action of converging torrents issuing from the tributary glaciers after the trunk was melted.

溪流剖面显示砾石沉积物由与冰碛相同的材料组成，但更细，并且在主干融化后从支流冰川流出的汇聚激流的作用下磨损更多。
