Distribution and Significance of Mesozoic Vertebrate Trace Fossils in Dinosaur National Monument

Geologic versus wildfire controls on hillslope processes and debris flow initiation in the Green River canyons of Dinosaur National Monument

As in many areas of high relief, debris flows are an important process linkage between hillslopes and the Green River in the canyons of the eastern Uinta Mountains, yet the physical conditions that lead to debris flow initiation are unknown. A recent episode of enhanced debris-flow and wildfire activity provided an opportunity to examine the geomorphic impact of fire and the processes by which ...

First Report on Reptile Tracks from the Moenkopi Formation (lower-?middle Triassic) in Dinosaur National Monument, Utah

The Lower-Middle Triassic Moenkopi and Red Peak formations, which crop out throughout western North America, contain ubiquitous occurrences of tetrapod tracks attributed to reptiles (Peabody, 1948; Klein and Lucas, 2010; Lovelace and Lovelace, 2012). Although reptile skeletal remains from these formations are rare to non-existent, and largely restricted to the Holbrook Member in Arizona (e.g., ...

Comparison of bacterial communities from lava cave microbial mats to overlying surface soils from Lava Beds National Monument, USA

Subsurface habitats harbor novel diversity that has received little attention until recently. Accessible subsurface habitats include lava caves around the world that often support extensive microbial mats on ceilings and walls in a range of colors. Little is known about lava cave microbial diversity and how these subsurface mats differ from microbial communities in overlying surface soils. To i...
