Gem Lake, Sierra Nevada, California
Here's a little example from my master's thesis area which shows a structural control on drainage along with the strong imprint of glacial flow. A mesozoic shear zone, about 1 kilometer in width, bounds the eastern edge of the Sierra Nevada Batholith. These sheared rocks have attained a transposition foliation which strikes roughly NNW. Due to differential weathering, some lithologies are more readily etched into lowlands, while others stand up as ridges. During the Pleistocene, alpine glaciers flowed out of the Sierras into the Owens Valley to the east, at approximately a 90° angle to the structural grain (ENE). Damming the drainage produced the body of water known as Gem Lake (37.749269 Lat, -119.150943 Long), which highlights the contours of the surrounding drainage by filling it all up with a horizontal layer of water.
