  • Chapter 2 Paleozoic Stratigraphy of the Grand Canyon
    CHAPTER 2 PALEOZOIC STRATIGRAPHY OF THE GRAND CANYON PAIGE KERCHER INTRODUCTION The Paleozoic Era of the Phanerozoic Eon is defined as the time between 542 and 251 million years before the present (ICS 2010). The Paleozoic Era began with the evolution of most major animal phyla present today, sparked by the novel adaptation of skeletal hard parts. Organisms continued to diversify throughout the Paleozoic into increasingly adaptive and complex life forms, including the first vertebrates, terrestrial plants and animals, forests and seed plants, reptiles, and flying insects. Vast coal swamps covered much of mid- to low-latitude continental environments in the late Paleozoic as the supercontinent Pangaea began to amalgamate. The hardiest taxa survived the multiple global glaciations and mass extinctions that have come to define major time boundaries of this era. Paleozoic North America existed primarily at mid to low latitudes and experienced multiple major orogenies and continental collisions. For much of the Paleozoic, North America’s southwestern margin ran through Nevada and Arizona – California did not yet exist (Appendix B). The flat-lying Paleozoic rocks of the Grand Canyon, though incomplete, form a record of a continental margin repeatedly inundated and vacated by shallow seas (Appendix A). IMPORTANT STRATIGRAPHIC PRINCIPLES AND CONCEPTS • Principle of Original Horizontality – In most cases, depositional processes produce flat-lying sedimentary layers. Notable exceptions include blanketing ash sheets, and cross-stratification developed on sloped surfaces. • Principle of Superposition – In an undisturbed sequence, older strata lie below younger strata; a package of sedimentary layers youngs upward. • Principle of Lateral Continuity – A layer of sediment extends laterally in all directions until it naturally pinches out or abuts the walls of its confining basin.

Introduction and Summary: The Paleontological Heritage of Grand Canyon National Park By Vincent L. Santucci1 1National Park Service Geologic Resources Division 1849 “C” Street, NW Washington, D.C. 20240 Throughout my life I have been bestowed the privilege of experiencing the world-renowned landscape and resources of the Grand Canyon from many perspectives and viewsheds (Figure 1-1). My first views were standing and taking photos from the many vantage points and overlooks along the North and South rims. I have enjoyed many hikes into the canyon with colleagues from the National Park Service (NPS) or with academic geologists and paleontologists. On a few occasions I ventured down and then back up the trails of the canyon with my children Sarah, Bethany, Luke, Jacob, Brianna and Abigail, often carrying one or more in my arms on the climb against gravity. I traversed by foot to the base of the canyon at Phantom Ranch and gained a greater appreciation for the geologic story preserved in the park strata. I have gazed intensely out the window of many commercial aircraft from above this geologic wonder of Earth, contemplating the geomorphic “grandeur” created over "Deep Time" and the artistry of processes perfected by “Mother Nature.” I pinch myself when I recall the opportunity when my friend Justin Tweet and I were granted permission to fly into the western portion of the Grand Canyon on a small NPS plane operated by a pilot from Lake Mead National Recreation Area.

  • Treasury's Emergency Rental Assistance
    FREQUENTLY ASKED QUESTIONS: TREASURY’SHEADING EMERGENCY1 HERE RENTAL ASSISTANCEHEADING (ERA)1 HERE PROGRAM AUGUST 2021 ongress established an Emergency Rental Assistance (ERA) program administered by the U.S. Department of the Treasury to distribute critically needed emergency rent and utility assistance to Cmillions of households at risk of losing their homes. Congress provided more than $46 billion for emergency rental assistance through the Consolidated Appropriations Act enacted in December 2020 and the American Rescue Plan Act enacted in March 2021. Based on NLIHC’s ongoing tracking and analysis of state and local ERA programs, including nearly 500 programs funded through Treasury’s ERA program, NLIHC has continued to identify needed policy changes to ensure ERA is distributed efficiently, effectively, and equitably. The ability of states and localities to distribute ERA was hindered early on by harmful guidance released by the Trump administration on its last day in office. Immediately after President Biden was sworn into office, the administration rescinded the harmful FAQ and released improved guidance to ensure ERA reaches households with the greatest needs, as recommended by NLIHC. The Biden administration issued revised ERA guidance in February, March, May, June, and August that directly addressed many of NLIHC’s concerns about troubling roadblocks in ERA programs. Treasury’s latest guidance provides further clarity and recommendations to encourage state and local governments to expedite assistance. Most notably, the FAQ provides even more explicit permission for ERA grantees to rely on self-attestations without further documentation. WHO IS ELIGIBLE TO RECEIVE EMERGENCY RENTAL ASSISTANCE? Households are eligible for ERA funds if one or more individuals: 1.

  • Critical Analysis of Article "21 Reasons to Believe the Earth Is Young" by Jeff Miller
    1 Critical analysis of article "21 Reasons to Believe the Earth is Young" by Jeff Miller Lorence G. Collins [email protected] Ken Woglemuth [email protected] January 7, 2019 Introduction The article by Dr. Jeff Miller can be accessed at the following link: http://apologeticspress.org/APContent.aspx?category=9&article=5641 and is an article published by Apologetic Press, v. 39, n.1, 2018. The problems start with the Article In Brief in the boxed paragraph, and with the very first sentence. The Bible does not give an age of the Earth of 6,000 to 10,000 years, or even imply − this is added to Scripture by Dr. Miller and other young-Earth creationists. R. C. Sproul was one of evangelicalism's outstanding theologians, and he stated point blank at the Legionier Conference panel discussion that he does not know how old the Earth is, and the Bible does not inform us. When there has been some apparent conflict, either the theologians or the scientists are wrong, because God is the Author of the Bible and His handiwork is in general revelation. In the days of Copernicus and Galileo, the theologians were wrong. Today we do not know of anyone who believes that the Earth is the center of the universe. 2 The last sentence of this "Article In Brief" is boldly false. There is almost no credible evidence from paleontology, geology, astrophysics, or geophysics that refutes deep time. Dr. Miller states: "The age of the Earth, according to naturalists and old- Earth advocates, is 4.5 billion years.

  • The Geologic Time Scale Is the Eon
    Exploring Geologic Time Poster Illustrated Teacher's Guide #35-1145 Paper #35-1146 Laminated Background Geologic Time Scale Basics The history of the Earth covers a vast expanse of time, so scientists divide it into smaller sections that are associ- ated with particular events that have occurred in the past.The approximate time range of each time span is shown on the poster.The largest time span of the geologic time scale is the eon. It is an indefinitely long period of time that contains at least two eras. Geologic time is divided into two eons.The more ancient eon is called the Precambrian, and the more recent is the Phanerozoic. Each eon is subdivided into smaller spans called eras.The Precambrian eon is divided from most ancient into the Hadean era, Archean era, and Proterozoic era. See Figure 1. Precambrian Eon Proterozoic Era 2500 - 550 million years ago Archaean Era 3800 - 2500 million years ago Hadean Era 4600 - 3800 million years ago Figure 1. Eras of the Precambrian Eon Single-celled and simple multicelled organisms first developed during the Precambrian eon. There are many fos- sils from this time because the sea-dwelling creatures were trapped in sediments and preserved. The Phanerozoic eon is subdivided into three eras – the Paleozoic era, Mesozoic era, and Cenozoic era. An era is often divided into several smaller time spans called periods. For example, the Paleozoic era is divided into the Cambrian, Ordovician, Silurian, Devonian, Carboniferous,and Permian periods. Paleozoic Era Permian Period 300 - 250 million years ago Carboniferous Period 350 - 300 million years ago Devonian Period 400 - 350 million years ago Silurian Period 450 - 400 million years ago Ordovician Period 500 - 450 million years ago Cambrian Period 550 - 500 million years ago Figure 2.

  • How Long Is a Year.Pdf
    How Long Is A Year? Dr. Bryan Mendez Space Sciences Laboratory UC Berkeley Keeping Time The basic unit of time is a Day. Different starting points: • Sunrise, • Noon, • Sunset, • Midnight tied to the Sun’s motion. Universal Time uses midnight as the starting point of a day. Length: sunrise to sunrise, sunset to sunset? Day Noon to noon – The seasonal motion of the Sun changes its rise and set times, so sunrise to sunrise would be a variable measure. Noon to noon is far more constant. Noon: time of the Sun’s transit of the meridian Stellarium View and measure a day Day Aday is caused by Earth’s motion: spinning on an axis and orbiting around the Sun. Earth’s spin is very regular (daily variations on the order of a few milliseconds, due to internal rearrangement of Earth’s mass and external gravitational forces primarily from the Moon and Sun). Synodic Day Noon to noon = synodic or solar day (point 1 to 3). This is not the time for one complete spin of Earth (1 to 2). Because Earth also orbits at the same time as it is spinning, it takes a little extra time for the Sun to come back to noon after one complete spin. Because the orbit is elliptical, when Earth is closest to the Sun it is moving faster, and it takes longer to bring the Sun back around to noon. When Earth is farther it moves slower and it takes less time to rotate the Sun back to noon. Mean Solar Day is an average of the amount time it takes to go from noon to noon throughout an orbit = 24 Hours Real solar day varies by up to 30 seconds depending on the time of year.
