迪纳利断层系共分两段;迪尔塔河以西为麦金利河道,迪尔塔河以东为多尔顿-沙克瓦克断层,这两段的几何形态几乎呈完整的小圆环状。根据刚性板块构造,这种几何形态可以解释沿这些断层发生的右侧滑动。它们的旋转极点在阿拉斯加湾,分别位于北纬59.63°、西经147.38°以及北纬50.38°,西经154.02°。有一个模型认为自38百万年以来这两条断层同时发生过运动;根据这个模式推测在这两条断层的交界处还存在第三条断层,而这条断层必然是一个板块的边界, Denali fault system is divided into two sections; west of the delta river is the McKinley River, east of the delta river is Dalton - Shakewak fault, the two sections of the geometry is almost complete small ring shape. According to the rigid plate tectonics, this geometry can account for the right-side slip that occurs along these faults. Their poles of rotation are in the Alaska Bay at 59.63 ° N, 147.38 ° W and 50.38 ° N and at 154.02 ° W. According to this model, there is a third fault at the junction of these two faults, and this fault is bound to be the boundary of one plate. According to this model,
