Abstract The distribution and elevation of the abandoned strath terraces along the Truckee River in the Carson Range on the eastern flank of the Sierra Nevada are mapped and quantified with measurements from Lidar accompanied by field survey. Each mapped strath terrace is formed by incision into the Hunter Creek Sandstone and deposition of fluvial gravel by the Truckee River. The gravel contains granitic boulders sourced from the glaciated headwaters of the Truckee >20 km upstream from the terraces and display boulders ranging from 4 to 12 m in dimension, in comparison to the

内华达山脉东北侧特拉基河阶地的开发

摘要 内华达山脉东翼卡森山脉特拉基河沿岸废弃地层阶地的分布和海拔通过激光雷达的测量和现场调查进行了绘制和量化。每个映射的地层阶地都是通过切入猎人溪砂岩和特拉基河沉积的河流砾石形成的。砾石包含花岗岩巨石，这些巨石来自于梯田上游 20 公里以上的特拉基冰川源头，并显示尺寸为 4 到 12 m 的巨石，相比之下，
