Powder River Geomorphic Mapping Supplement

Geomorphic mapping of the Powder River, Montana between Moorhead and Broadus USGS gaging stations. Files are supplementary to "Floodplain Sediment Storage Timescales of the Meandering Powder River, U.S.A." by Huffman et al., 2021.<br>Lateral accretion and alluvial terraces maps were created by Sheila Trampush. Channel positions and dendrochronology data was created by Derek Schook.

美国蒙大拿州境内，位于莫尔黑德（Moorhead）与布罗德（Broadus）美国地质调查局（USGS）测流站之间的鲍威尔河（Powder River）地貌测绘数据集。本数据集文件为Huffman等人2021年发表的《美国蜿蜒型鲍威尔河漫滩沉积物存储时间尺度》研究论文的补充材料。侧向加积（lateral accretion）与冲积阶地（alluvial terraces）分布图由希拉·特兰普什（Sheila Trampush）绘制。河道位置与树木年代学（dendrochronology）数据由德里克·舒克（Derek Schook）生成。
