Long day of hauling in and emplacing seismometers in Rocky Mountain National Park. The seismometers were emplaced by local rivers to detect their interference and sort it out from the deep seismicity being studied. The trails were flooded out and the rivers were running high and strong after a rainy week, everyone had to pitch in to keep Dr. Rathburn from being swept up while taking stream readings! Amazing view from the river while collecting soil samples with Dr. Sutfin for his dissertation research and my independent study in Rocky Mountain National Park. We collected floodplain soils for grain size analysis and determination of organic carbon content.My first day as an Introductory Geology lab instructor. I felt honored being given such a responsibility as an undergraduate student, and had a great time sharing the wonders of geology with my class. I even managed to get a few to change their major! Sherman Granite of the Virginia Dale Complex in Larimer County, Colorado shown in cross-polarized light under polarized microscope and in hand sample. Active point bar in the Cache La Poudre River of Northern Colorado, 1.7 meter-tall field partner for scale! Alternating gray limestone and red sandstone layers of the Ingleside Formation in Owl Canyon, Larimer County, Colorado. It was a cold and wet day with my field partners!Mapping the geology of the Lime Creek area outside of Silverton, CO, we definitely got our steps in that week! There was an abundance of interesting structural features, like this reverse fault in the Hermosa Formation.Geologic mapping of the Silverton Caldera complex in the Red Mountain Pass outside of Silverton, Colorado. It was a beautiful and diverse landscape, with lush valleys and snow-capped peaks above 13,000 feet.Mapping and doing some field chemistry outside of Taos, New Mexico.Stratigraphic columns of limestone outcrops in Molas Pass, Colorado.Soil survey map in Niagara County, New York I created in ArcGIS for a project on the Love Canal environmental incident.
