Martian Crater Morphology
ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter. -

A Collections Management Plan (CMP) (precursor to the current Museum Management Plan format) was completed in 1995, and the park has had the services of a journeyman-level curator for 12 years. Despite the age and maturity of the park, these park-specific resources remain in a developmental stage. They lack status, definition, and support, and thus are not able to efficiently contribute to park operations. Few of the recommendations in the 1995 CMP have been implemented. With the continued influx of collections, the documentation program and physical facilities are in worse condition now than in 1995. These deficiencies could be corrected by the following actions: • Developing internal protocols to govern collections growth, processing, and access. -

Overview for Geologic Field-Trip Guides to Mount Mazama, Crater Lake Caldera, and Newberry Volcano, Oregon
Overview for Geologic Field-Trip Guides to Mount Mazama, Crater Lake Caldera, and Newberry Volcano, Oregon Scientific Investigations Report 2017–5022–J U.S. Department of the Interior U.S. Geological Survey Cover (top photo): View east-northeast from Garfield Peak on the south rim of Crater Lake caldera. Peak on skyline is 8,929 feet (2,722 meters) Mount Scott, an ~420 thousand years before present (ka) dacite stratovolcano considered to be part of Mount Mazama, the volcano that collapsed during the caldera-forming eruption ~7,700 years ago. The caldera walls in this view expose Mazama lava flows and fragmental deposits from as old as ~400 ka at Phantom Cone, adjacent to tiny Phantom Ship island, to as young as ~27 ka at Redcloud Cliff, the V-shaped face at the top of the wall left of center. The beheaded glacial valley of Kerr Notch, the low point on the caldera rim, is seen between Phantom Ship and Mount Scott. Photograph by Carly McLanahan. Cover (bottom photo): Newberry Volcano, Oregon, is the largest volcano in the Cascades volcanic arc. This north-facing view taken from the volcano’s peak, Paulina Peak (elevation 7,984 feet), encompasses much of the volcano’s 4-by-5-milewide central caldera, a volcanic depression formed in a powerful explosive eruption about 75,000 years ago. The caldera’s two lakes, Paulina Lake (left) and the slightly higher East Lake (right), are fed in part by active hot springs heated by molten rock (magma) deep beneath the caldera. The Central Pumice Cone sits between the lakes. -
Appendix I Lunar and Martian Nomenclature
APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject. For further references see: [AU Trans. X, 259-263, 1960; XIB, 236-238, 1962; Xlffi, 203-204, 1966; xnffi, 99-105, 1968; XIVB, 63, 129, 139, 1971; Space Sci. Rev. 12, 136-186, 1971. Because at the recent General Assemblies some small changes, or corrections, were made, the complete list of Lunar and Martian Topographic Features is published here.

Introduction to Crater Lake
National Park Service Crater Lake U.S. Department of the Interior Crater Lake National Park Introduction to Crater Lake Crater Lake Is Like No Crater Lake has inspired its visitors for hundreds of years. No place else on earth Place Else On Earth combines such a deep, pure lake with sheer surrounding cliffs and a violent volcanic past. Few places on earth are so beautiful, so pristine, or—for these very reasons—so interesting to scientists. An Introduction to Crater Lake is located in Southern Oregon on the Following the collapse of Mount Mazama, lava Crater Lake crest of the Cascade Mountain range, 100 miles poured into the caldera even as the lake began to (160 km) east of the Pacific Ocean. It lies inside a rise. Today, a small volcanic island, Wizard Island, caldera, or volcanic basin, created when the 12,000 appears on the west side of the lake. This cinder foot (3,660 meter) high Mount Mazama collapsed cone rises 767 feet (234 meters) above the lake and 7,700 years ago following a large eruption. is surrounded by black volcanic lava blocks.

USGS Scientific Investigations Map 2832, Pamphlet
Geologic Map of Mount Mazama and Crater Lake Caldera, Oregon By Charles R. Bacon Pamphlet to accompany Scientific Investigations Map 2832 View from the south-southwest rim of Crater Lake caldera showing the caldera wall from Hillman Peak on the west to Cleetwood Cove on the north. Crater Lake fills half of the 8- by 10-km-diameter caldera formed during the climactic eruption of Mount Mazama volcano approximately 7,700 years ago. Volcanic rocks exposed in the caldera walls and on the flanks record over 400,000 years of eruptive history. The exposed cinder cone and andesite lava flows on Wizard Island represent only 2 percent of the total volume of postcaldera volcanic rock that is largely covered by Crater Lake. Beyond Wizard Island, the great cliff of Llao Rock, rhyodacite lava emplaced 100–200 years before the caldera-forming eruption, dominates the northwest caldera wall where andesite lava flows at the lakeshore are approximately 150,000 years old. 2008 U.S. Department of the Interior U.S. Geological Survey This page intentionally left blank.
