What is this (N 34.64914 W 111.75221) karst landform,
how did it form, and what is the elevation difference between the water in this landform and the stream immediately to the east?
This landform is a collapse doline formed by the dissolution of rock (limestone) in a cavern. Then, when the cavern ceiling collapsed this sinkhole formed. The elevation of the river to the east is a few meters lower than the lake.
This landform is a sinkhole formed by faulting dropping down the basin. The river to the east is a few meters lower than the lake in the sinkhole.
This landform is a blind valley formed by fluvial processes eroding the depressions, and the river to the east is about 10 meters higher than the lake surface.
This landform is a caldera formed by the collapse of the volcanic basalt lava upon evaluation of the lava. The current lake surface is the same elevation as the river to the east.
What is this karst landform (N 37.81090 W 80.49637) and how did it form? Hint: this is the end of Milligan Creek. Where does it go from this point?
This blind valley formed because the water goes down into an underground cave system.
This offset stream formed when a fault separated the upstream portion of the stream from its downstream segment.
This interrupted stream formed because the water goes down a sinkhole into an underground water storage system built by the surrounding farms.
This dead-end stream was built during the civil war as a trap for the union army.
