在这里提出的假设中，帕纳明特山脉是一个构造块体，在新生代晚期从现在形成黑山的下层岩石中分离出来，并被构造搬运到西北部估计80公里处。运输发生沿着一个单一的低角度西倾拆离断层，或可能沿着一个系统的这种故障。80 km的搬运距离的估计是基于晚前寒武纪和古生代相的明显右侧偏移以及沿沿着Furnace Creek断裂带的厚度趋势，该断裂带界定了东北方向的分离块体。死亡谷的龟背表面被认为是巨大的竖框有关的剥离表面。
In the hypothesis presented here, the Panamint Range is a structural block that was detached during late Cenozoic time from underlying rocks that now form the Black Mountains and was transported tectonically an estimated 80 km to the northwest. Transport occurred along a single low-angle westward-dipping detachment fault, or perhaps along a system of such faults. The estimate of 80 km of transport distance is based on the apparent right-lateral offset of late Precambrian and Paleozoic facies and thickness trends along the Furnace Creek fault zone that bounds the detached block on the northeast. The Death Valley turtleback surfaces are considered to be gigantic mullions related to the detachment surface.
