15,000 years ago, glaciers covered central Wisconsin from the northeast extending to just east of present day Wausau and Stevens Point. As the climate warmed, glaciers released torrents of melt water causing deep gorges in locations throughout Wisconsin.  One such area can be seen just north of Hatley, the Dells of the Eau Claire River. On this stretch, the Eau Claire River cascades over outcrops of Precambrian-age rhyolite schist.  Rhyolite schist (a very hard rock) was formed through metamorphosis and later tilted to a nearly vertical position allowing the rock to split readily along the cleavage planes. In the dells, the river tumbles and spills across the rock’s cleavage planes while it runs smoothly in other areas where the river flows parallel to the planes. This image is looking upstream from the Dells just east of the bridge.

This is an HDR image. Several different exposures of the same scene were taken by changing only the shutter speed. The images were then combined using Photoshop and Photomatix.
