Pierce County is underlain by Cambrian and Ordovician strata, primarily quartz sandstones and dolomitic carbonates. A few isolated outcrops of non-marine Cretaceous strata are known. There is a relatively thin cap of glacial drift left by earlier Pleistocene glaciations. An Ordovician meteor impact structure, the Rock Elm Disturbance, occurs in the eastern part of the County in and north of Nugget Lake County Park. Drusy quartz, dolomite, calcite and goethite pseudomorphs after pyrite occur often in dolostone quarries and outcrops. Crystal Cave in Spring Valley is a significant commercial cave developed in the Ordovician Prairie du Chien Group dolostones and displays speleothems as well as the drusy quartz in vugs that give the cave its name. A few small iron oxide ore deposits were mined from likely Cretaceous lag deposits on top of Ordovician carbonate rocks. The glacial drift hosts a variety of minerals, including drift gold, copper and diamonds, septaria nodules, jasper, banded iron formation and, of course, Lake Superior agates. Several geology displays can be found in the Agriculture and Science Hall on the University of Wisconsin - River Falls campus.

Note that some localities are named after roads. Be warned that road names in the county have been changed to numbers, with east-west roads being numbered avenues and north-south roads being numbered streets.
