9714894 McDonald The Cascade range in Washington state is unusual because it is an actively rising range in a forearc region. Existing seismic studies have emphasized very young movements, and have shown that the local convergence is N-S. However, the longer deformation signal is not well known. This proposal will use river profiles, fluvial deposits and geomorphology to measure uplift rates in the Olympic Mountains on the scale of tens of thousands of years. This study will yield exportable results by establishing how quantitatively geomorphologic processes can be correlated with long term deformation in a tectonically active region.

9714894麦当劳华盛顿州的喀斯喀特山脉是不寻常的，因为它是前牙前地区的积极上升范围。 现有的地震研究强调了非常年轻的运动，并表明局部收敛是N-S。 但是，较长的变形信号尚不清楚。 该提案将使用河流概况，河流沉积物和地貌学来测量奥林匹克山脉的提升率，以数十万年的规模。 这项研究将通过确定如何与构造活性区域的长期变形相关的定量地貌过程来产生可导出的结果。
