The Geology of the Limespur-Sappington Area

The area to be surveyed was divided up into sections add each crew of three or four members was assigned one of these sections. The first two days were spent in studying and mapping the geologic section in the South Boulder Canyon where we obtained practice in alidade surveying, brunton, pacing, and auto traverse.

Geological Report of Summer Field Trip 1928

The object of this trip and report was to familiarize the students of the Montana State School of Mines with methods of taking and mapping surface and undergound geology. All surface geology was mapped by means of plane table and alidade, and undergound work by means of Brunton compass and taps. The senior class of the Montana State School of MInes under the supervision of Dr. E.S. Perry performed the work, which covered an area in Madison County including South Boulder Creek, near Jefferson Island, the Silver Star Mining District, and the Alameda Mine, near Virginia City.

Expert-novice Differences in Geologic Field Mapping and Related Cognition

The geosciences are often characterized as a visuospatial field - that is, one in which success depends upon the ability to mentally manipulate, rotate, project, and bend objects. To what extent is the assumption of strong spatial visualization skills among geoscientists correct? This talk will discuss two studies that investigated geoscience expert and novice spatial visualization, both in laboratory experiments and in a novel field study.
