In early September, 1981, core from three drill holes was taken from Laramie to Golden for preparation of standard specimens for paleomagnetic measurements. The pieces of drill core were drilled perpendicular to their axis; with large pieces of core, several specimens were prepared from each piece. A breakdown of the number of cylinders collected over specific drilling intervals from each hole is given in Table 1. In some instances, the core is so fragile or so poorly consolidated that standard drilling techniques did little to retrieve cylinders. In these cases, whole portions of core were retained and cubicle specimens prepared to fit into small, plastic boxes which could be measured directly. The burned material collected from the Hoe Creek sites was simply based as coarse grit during the field drilling procedures. In these cases, a small vial of material was collected from each bag.
