This is one of many related papers that were included in the 2021 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, Color Plates, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

U.S. Highway 89 leads south toward the entrance to Grand Canyon National Park and Flagstaff. For a route description along U.S. Highway 89 northward from here see HW-89A Road Guide.. The road junction is in the Petrified Forest Member of the Chinle Formation. The member is composed of interbedded stream channel sandstone and varicolored shale and mudstone. This member erodes moderately easily and forms the strike valley to the north and south. From here the route of this guide leads upsection into younger and younger beds of the Chinle Formation. 0.7 Cross Hamblin Wash and rise from the Petrified Forest Member into the pinkish banded Owl Rock Member of the Chinle Formation. The upper member forms pronounced laminated pinkish gray and green badlands, distinctly unlike the rounded Painted Desert-type massive badlands of the underlying member. 1.6 Road rises up through the upper part of the Chinle Formation, a typical wavy to hummocky road. Highway construction is easy across the slope-forming parts of the formation, but holding the road after construction is difficult because the soft volcanic ash-bearing shales heave under load or after wetting and drying.

    GEOLOGY OF THE MOAB REGION (Arches, Dead Horse Point and Canyonlands) Annabelle Foos Geology Department, University of Akron Introduction The geology of Arches National Park, porphyry laccolith that was intruded during the Dead Horse Point State Park and the “Island in Oligocene, 30 million years ago and the Sky” section of Canyonlands National Park experienced glaciation during the Pleistocene. is very similar. They occur in the Canyonlands Melting snow which accumulates in the section of the Colorado Plateau, in the vicinity mountains during winter months, replenishes of the confluence between the Green and streams and recharges bedrock aquifers Colorado Rivers. The same stratigraphic units providing a valuable source of fresh water to outcrop in all three parks (figure 1) plus salt this region. (Doelling and others, 1987) tectonic features can be found in both Arches and Canyonlands. While in the Moab region you will become familiar with some of the stratigraphic units we will see throughout the Colorado Plateau, observe salt tectonic features, arch formation and in the distance you can view the La Sal Mountains. Cryptogamic Soils While in these three parks (and throughout this trip) you will be required to STAY ON THE DESIGNATED TRAILS. This rule is especially important at these parks in order to preserve the fragile cryptogamic soils (figure 2). Cryptogamic soils are a complex of lichens, algae, moss and fungus that occurs as a black coating on the ground surface and as small mounds where it is well developed. It plays an extremely important role in the desert ecology. It binds the soil together and inhibits wind erosion and erosion by sheet wash.
