卡塞山谷形成了火星上最大的外流通道系统。在这里，构成卡塞山谷的峡谷壁和底部的材料与洪水沃茨的来源一起被调查沿着。据建议，通过卡塞山谷削减高原材料的地质序列是由脊状平原材料覆盖相对较弱的Noachian高原材料，增加抗侵蚀低于1000米的深度。洪水开始于晚期西方，可能起源于塔尔西斯隆起，这里的火山构造活动产生了很高的地下水压力。地下水通过1000 m深处的抵抗带上方的水力压裂流出，并在北方卡塞山谷喷发，形成了主要为东北走向的Sacra Fossae槽，并在脊状平原材料中蚀刻接缝。一些洪水侵入了诺亚纪高原物质的上部薄弱地带，产生了低起伏的混乱和多节地形。
Kasei Valles form the most immense outflow channel system on Mars. Here, the materials that make up the canyon walls and floors of Kasei Valles are investigated along with the sources of the flood waters. It is proposed that the geological sequence of plateau materials through which Kasei Valles cuts is capped by ridged plains material overlying relatively weak Noachian plateau materials that increase in resistance to erosion below 1000 m depth. Flooding began in the Late Hesperian, probably originating from the Tharsis rise, here volcanotectonic activity produced high ground-water pressures. Ground water sluiced through hydrofractures above the resistant zone at 1000 m depth and erupted in northern Kasei Valles, forming mostly northeast-trending troughs of Sacra Fossae and etching joints in the ridged plains material. Some of the flood water invaded the upper weak zone of the Noachian plateau materials, producing chaotic and knobby terrains of low relief.
