Elevation contours of the Precambrian surface of south-central Wisconsin

Elevation contour data and an accompanying report provide an updated interpretation of the elevation of the top of Precambrian bedrock in south-central Wisconsin. The elevation surface was developed from geologic and geophysical data, and provides new detail on the entrenched bedrock valleys that were incised into the north and south ranges of the Baraboo Hills. The GIS data include elevation contours, faults, locations of Precambrian outcrops, locations of wells that intersect the Precambrian surface at depth, and historic drill records.

高程等值线数据及配套报告，对美国威斯康星州中南部前寒武纪（Precambrian）基岩顶面的高程开展了更新解译。本数据集的高程表面基于地质与地球物理数据构建，详细呈现了切入巴拉布岭（Baraboo Hills）南北两坡的深切基岩河谷的全新细节。本次提供的地理信息系统（Geographic Information System，GIS）数据涵盖高程等值线、断层、前寒武纪露头点位、深部与前寒武纪界面相交的钻井点位，以及历史钻井记录。
