Michael Kenney Paleozoic Stratigraphy of the Grand Canyon
Michael Kenney Paleozoic Stratigraphy of the Grand Canyon The Paleozoic Era spans about 250 Myrs of Earth History from 541 Ma to 254 Ma (Figure 1). Within Grand Canyon National Park, there is a fragmented record of this time, which has undergone little to no deformation. These still relatively flat-lying, stratified layers, have been the focus of over 100 years of geologic studies. Much of what we know today began with the work of famed naturalist and geologist, Edwin Mckee (Beus and Middleton, 2003). His work, in addition to those before and after, have led to a greater understanding of sedimentation processes, fossil preservation, the evolution of life, and the drastic changes to Earth’s climate during the Paleozoic. This paper seeks to summarize, generally, the Paleozoic strata, the environments in which they were deposited, and the sources from which the sediments were derived. Tapeats Sandstone (~525 Ma – 515 Ma) The Tapeats Sandstone is a buff colored, quartz-rich sandstone and conglomerate, deposited unconformably on the Grand Canyon Supergroup and Vishnu metamorphic basement (Middleton and Elliott, 2003). Thickness varies from ~100 m to ~350 m depending on the paleotopography of the basement rocks upon which the sandstone was deposited. The base of the unit contains the highest abundance of conglomerates. Cobbles and pebbles sourced from the underlying basement rocks are common in the basal unit. Grain size and bed thickness thins upwards (Middleton and Elliott, 2003). Common sedimentary structures include planar and trough cross-bedding, which both decrease in thickness up-sequence. Fossils are rare but within the upper part of the sequence, body fossils date to the early Cambrian (Middleton and Elliott, 2003). -

Grand Canyon Archaeological Site
ARCHAEOLOGICAL SITE ETIQUETTE POLICY ARCHAEOLOGICAL SITE ETIQUETTE POLICY For Colorado River Commercial Operators This etiquette policy was developed as a preservation tool to protect archaeological sites along the Colorado River. This policy classifies all known archaeological sites into one of four classes and helps direct visitors to sites that can withstand visitation and to minimize impacts to those that cannot. Commercially guided groups may visit Class I and Class II sites; however, inappropriate behaviors and activities on any archaeological site is a violation of federal law and Commercial Operating Requirements. Class III sites are not appropriate for visitation. National Park Service employees and Commercial Operators are prohibited from disclosing the location and nature of Class III archaeological sites. If clients encounter archaeological sites in the backcountry, guides should take the opportunity to talk about ancestral use of the Canyon, discuss the challenges faced in protecting archaeological resources in remote places, and reaffirm Leave No Trace practices. These include observing from afar, discouraging clients from collecting site coordinates and posting photographs and maps with location descriptions on social media. Class IV archaeological sites are closed to visitation; they are listed on Page 2 of this document. Commercial guides may share the list of Class I, Class II and Class IV sites with clients. It is the responsibility of individual Commercial Operators to disseminate site etiquette information to all company employees and to ensure that their guides are teaching this information to all clients prior to visiting archaeological sites. Class I Archaeological Sites: Class I sites have been Class II Archaeological Sites: Class II sites are more managed specifically to withstand greater volumes of vulnerable to visitor impacts than Class I sites. -
