  • Quicksilver Deposits of Steens Mountain and Pueblo Mountains Southeast Oregon
    Quicksilver Deposits of Steens Mountain and Pueblo Mountains Southeast Oregon GEOLOGICAL SURVEY BULLETIN 995-B A CONTRIBUTION TO ECONOMIC GEOLOGY QUICKSILVER DEPOSITS OF STEENS MOUNTAIN AND PUEBLO MOUNTAINS, SOUTHEAST OREGON By HOWEL WILLIAMS and ROBERT R. The object of this survey was to examine the quicksilver deposits with the hope of locating large tonnages of low-grade ore. The deposits occur in the south-central part of Harney County and are more than 100 miles from either Burns, Oreg., or Winuemucca, Nev., the nearest towns. The region is sparsely settled by stockmen; Fields, Denio, and Andrews are the only settlements. The range consisting of Steens Mountain and Pueblo Mountains is a dissected fault block, 90 miles long in a north-south direction and as much as 25 miles wide, tilted gently to the west. Pre-Tertiary rnetarnorphic and plutonic rocks occur at the southern end, but most of the block consists of Pliocene volcanic rocks. The major boundary faults on the east side of the range are concealed by alluvium. Minor northwestward-trending faults branch from them, their throws diminish­ ing toward the crest of the range; other minor fractures occur near, and parallel to, the mountain front. The quicksilver lodes were formed in and along these subsidiary fractures. The lodes occur in a more or less continuous belt just west of the eastern front of the range. They are steeply dipping and arranged in subparallel clusters, commonly standing out as resistant siliceous ribs against the softer kaolinized rocks that flank them. The lodes were formed in two hydrothermal stages, the first producing the reeflike masses of chalcedony and quartz with their halos of limonitic and calcitic clays and the second introducing silica and barite along with sulfides of iron, copper, and mercury.

  • Geology of the South-Central Pueblo Mountains, Oregon-Nevada
    AN ABSTRACT OF THE THESIS OF WINTHROP ALLEN ROWE for the MASTER OF SCIENCE (Name) (Degree) in GEOLOGY presented on lurd IL 1q4() Major) (Sate) Title: GEOLOGY OF THE SOUTH-CENTRAL PUEBLO MOUNTAINS, OREGON-NEVADA Abstract approved: Redacted for Privacy Dr. Harold E. En lows The thesis area consists of 33 square miles in the south-central Pueblo Mountains of Humboldt County, Nevada and Harney County, Oregon.The Pueblo Mountains are tilted fault block mountains found in the extreme northwestern part of the Basin and Range province and were produced during Early Tertiary Basin and Range orogeny. Northwest and northeast trending faults of Late Tertiary time have since cut the entire stratigraphic sequence. The oldest rocks exposed are metamorphosed Permian to Triassic eugeosynclinal sedimentary rocks.The metamorphic sequence is intruded by several granitic plutons of Late Jurassic to Middle Cretaceous age. A thick sequence of Miocene basalt flows unconformably overlies the pre- Tertiary rocks. A slight angular unconformity separates the basalt sequence from overlying Miocene tuffaceous sedimentary rocks, sillar flows, and welded tuffs. Unconsolidated deposits of Quaternary alluvium include alluvial fan and lacustrine sediments. Mineralization within the area includes several gold prospects, a mercury prospect, and a possible copper deposit.The copper prospect consists of a large gossan (6, 000 feet by 3, 000 feet). Mineralization and alteration from a Cretaceous porphyritic quartz monzonite intrusion has produced potassic and quartz sericite

  • Mountain Quail Translocations in Eastern Oregon Trout Creek
    1 Mountain Quail Translocations in Eastern Oregon Project Report: 2008 Trout Creek Mountains Chad Abel, Mountain Quail Technician ODFW Hines District Office P.O. Box 8 Hines, OR 97738 541/573.6582 2 INTRODUCTION Mountain Quail were once considered common in southeast Oregon’s Harney County (Jackle et al. 2002). Finley (1915) commented that Mountain Quail were found in considerable numbers in Harney County, and Fawcett (1914) reported observations of large Mountain Quail coveys on the Alvord Ranch southeast of Steens Mountain (in Jackle et al. 2002). As the century progressed however, Mountain Quail declined to near extirpation in many areas of the western Great Basin, likely as a result of habitat loss due to overgrazing, fire suppression and water impoundment projects (Brennan 1991, 1994 in Gutierrez and Delehanty 1999). The Mountain Quail of Harney County were without exception. From 1980-2003 there were only 5 documented sightings of Mountain Quail in Harney County with only 1 sighting during that timeframe south of the Steens Mountain fault block (see Appendix, pg. A). In 2004 the Oregon Department of Fish and Wildlife, the U.S. Forest Service and the Game Bird Program at OSU began releasing Mountain Quail in Harney County as part of a broader Mountain Quail translocation and research program for eastern Oregon. The project goal is to actively restore populations of Mountain Quail to historic ranges in eastern Oregon where populations have declined or been extirpated. Between 2004 and 2007 the program translocated 409 Mountain Quail from healthy populations in southwest Oregon to Malheur National Forest and Steens Mountain in Harney County.

  • Pilot Project Tests Megafire Prevention Methods National Environmental Policy Act Approved Pueblo Mountain Pilot Project Focuses Megafire Prevention Studies
    Pilot Project Tests Megafire Prevention Methods National Environmental Policy Act approved Pueblo Mountain Pilot Project focuses megafire prevention studies. By Lauren Brown Photography by Jeremy Hill October 2019 The​ Harney County Wildfire Collaborative​ began testing megafire prevention methods in September with a pilot project in a high fire risk area at the south end of the Pueblo Mountains. Formed in 2014, the Harney County Wildfire Collaborative, a collaborative of the High Desert Partnership, has brought together representatives from county, federal and state agencies, local Rangeland Fire Protection Associations, the Burns Paiute Tribe, conservation groups, as well as scientists and ranchers to facilitate conversations around how to fight and prevent megafires in Harney County. The group’s first major project is the National Environmental Policy Act approved Pueblo Mountain Pilot Project, which focuses on preventing a megafire in that area by creating a vegetated fuel break along a road corridor between Oregon End Table and Hawks Valley where firefighters can more safely operate and reduce the risks of a fire spreading northeast into the Pueblo Mountains. The project, which is being implemented by the​ ​Bureau of Land Management (BLM)​, will replace invasive annual grasses with native bunch grasses in a portion of the test pilot area through prescribed burning that began September 2019, followed by spraying and seeding with native grasses. The project will eventually also improve fire detection methods by installing mountain-top cameras to reduce response time. Road improvements already completed will dramatically improve firefighting equipment access to the area. Autumn Larkins, formerly an assistant district wildlife biologist with the Oregon Department of Fish and Wildlife in Hines, said that in addition to protecting an area where there is a high potential for ecological change, the collaborative also hopes to protect areas where there has been previous substantial restoration.

The advent of the Space Age brought high-energy fuels into sharp focus. Boron compounds have offer­ ed promise as on important component of these fuels and have received much publ icity in this connection. Thus attention has been directed to possible new sources of boron even though no shortage of domestic sup­ pi i es can be foreseen at present. Around the turn of the present century borax was harvested commercially from crusts formed on the sur­ face of Alvord Volley, south of Alvord Lake, in southern Harney County, southeastern Oregon, just east of the famous Steens-Pueblo Mountains. In 1957-58 a minor boom developed in applications for prospecting permits on federal land in the gen­ eral vicinity of Alvord Lake basin. The present paper describes the conditions of boron occurrence in the basin and attempts to bring developments in the area up to date. In July, 1947, the author was in the basin locality and sampled the water of Hot Lake at one outlet; the assay returned 80 p. p. m. of B203. During the last week of August and the first week of September, 1960, the area was revisited and thermal springs sampled as described in the following text.

  • Gambelia Wislizenii)
    AN ABSTRACT OF THE THESIS OF Edith Moore for the degree of Master ofScience in Zoology presented on August 16, 1983 Title:The Function of Orange Breeding Coloration in the Social Behavior of the Long-nosed Leopard Lizard (Gambelia wislizenii) Abstract approved: _Redacted for Privacy Dr. Robert M. Storm The role of orange coloration in the breeding behavior of Gambelia wislizenii was examined in the Alvord Basin of southeast Oregon. Behavioral observations of free ranging lizards supplemented field experiments where I manipulated the sex and color of lizards encountered by resident female G. wislizenii before and after they acquired orange coloration. G. wislizenii exhibited a behavioral repertoire typical of the family Iguanidae. Twenty-four behaviors were observed and discussed in the text. Female G. wislizenii avoided plain females and males early in the breeding season, while males courted both indiscriminately. Female avoidance forced males to pursue females in order to secure the neck grip necessary for copulation. Female coyness may exert selective pressure on males to display characteristics thatwould improve their offspring's chances of survival. Possible advantages of male-male "courtship" are discussed. Most orange females were unreceptive to male courtship and reacted with overt aggression to such advances. Males may maintain a neck grip on females for up to three hours, thereforeit is to a gravid female's advantage to discourage male courtship, and thus avoid unnecessary incapacitation. The high level aggression of orange females was usually an effective deterrent to male courtship; however, a rape strategy was substituted for courtship on occasion. The rape strategy was characterized by 10-20 m headlong dashes ending in a tackle of the female.
