This work is the product of an archaeological investigation of the former townsite of Dallas, Colorado. Archival research, drone photography, shovel test pits (STPs), and a test excavation unit were employed to learn more about how the people of Dallas lived, and how they interacted with national sy

Soils form a complex part of the environment, providing important functions in systems such as food production, groundwater movement, and ecosystem health. There have been numerous studies on soil geochemistry and the origin of elements within soils, but few studies into quantifying the relationship

Cheaters affect most mutualisms, but their effects remain misunderstood. This thesis

Precambrian metamorphic and igneous rocks, Paleozoic sedimentary rocks, and Tertiary igneous and sedimentary rocks crop out in the northern Sangre de Cristo Range. Miocene (?) age normal faults, Late Cretaceous or Early Tertiary thrust faults, and Paleozoic (?) reverse faults have displaced Precambr

Biotic and Abiotic Drivers of Plant-Pollinator Interaction Rewiring

A Mid-Tertiary igneous intrusion into the Upper Cretaceous Mancos Shale provides an excellent natural laboratory to study the thermal effects of an intrusion on the organic geochemistry and water-rock system across a contact metamorphic profile. The intrusion, is believed to have established a high

In the northeast San Juan Mountains of southwest Colorado lie the Powderhorn and La Garita Wilderness Areas, full of high peaks and alpine plateaus bordered by volcanic hoodoos, vast forests, and arid steppe. A floristic inventory was performed to describe and catalog the vascular plant diversity of
