A subsurface and surface structural study was completed in the southwest part of the Elk Basin Anticline, Wyoming. The goals of this study were to better improve preexisting geologic surface maps of the area and to better understand subsurface structural relationships. A normal fault with a splay to the north was recorded through sections 25, 26. and 35 of T58N, RI00W. Using well logs to create across section, this fault was traced in the subsurface. Strike and dip measurements in undisturbed areas of the anticline averaged 332° (azimuth) or N28W (quadrant). In an area of anomalous strike (section 26 of T58N, R1 00W), strike readings averaged 303° (azimuth) or N57W (quadrant). This region has been interpreted as an area rotated counter clockwise due to drag on a subsurface tear fault located at the northern end of the anticline. The current study is significant since it lends support to a little studied Laramide structural feature. / Department of Geology
