The Lewis and Clark line which extends from northern Idaho to southwestern Montana separates a number of large-scale tectonic features of several ages. The origin and development of the Lewis and Clark line are complex and poorly understood. This project will attempt to unravel the multiple-phase tectonic evolution of the Lewis and Clark line by mapping, kinematic analysis and thermochronology. The results are expected to enhance our knowledge of the Lewis and Clark line and its role in the develop- ment of the North American Cordillera.

从爱达荷州北部延伸到蒙大拿州西南部的刘易斯-克拉克线分隔了几个年代的大型构造特征。刘易斯和克拉克线的起源和发展是复杂的，人们对其知之甚少。该项目将试图通过制图、运动学分析和热年代学来揭示刘易斯和克拉克线的多阶段构造演化。研究结果有望增进我们对刘易斯-克拉克线及其在北美科迪勒拉山脉形成过程中所起作用的认识。
