Name: Blue Mounds State Park Outcrop

Display Field: rk_name1

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Contains outlines that approximate the limits of nearly 3000 bedrock exposures in and adjacent to the park. These were drawn from field mapping using air photo imagery supplied by DNR (BlueMoundsStPark.tif), augmented locally by LiDAR imagery (in tree-obscured areas) and other air photo data sets available through GIS on-line. The outlines of LiDAR-based outcrops are speculative, especially along the bluff that marks the east and southeast sides of the park. The greatest outline detail attainable from the imagery was scale 1:1,000. Outlines locally enclose clusters of multiple, closely spaced exposures. Outlines are approximate and many small outcrops likely exist that are not included. Some outcrops drawn may actually be boulders. Obviously, not all outcrops shown were visited during field work. In general, outcrops of pale purple and pink, trough cross-bedded units are more prominent than those composed of red and dark purple, more thinly planar-bedded units. Outcrops of the pale units tend to be equidimensional and polygonal; with blocky joints, comparatively high topographic expression, and pale color apparent in air photographs. In some locations, these exposures are segmented into blocks by frost-heaving along joint surfaces. By contrast, the red units tend to form long, sinuous, and narrow outcrops that are low to the surrounding land surface and typically dark colored in air photographs. Locally the contact between the two types of units is visible on air photos. These differences in outcrop morphology are related to contrasting bed thickness - pale colored units are thickly bedded and massive; red units are more thinly bedded. A likely explanation is that bedding plane fractures and more closely spaced vertical fractures in red units allowed glaciers to more effectively pluck and remove fragments
