  • New Wildfire in Trout Creek Mountains Area
    Contact: Tara Martinak (541) 573-4400 Release No. OR-BU-12-23 July 25, 2012, 9:00 a.m. NEW WILDFIRE IN TROUT CREEK MOUNTAINS HINES, Ore. – Two random lightning strikes in southeast Oregon late Tuesday afternoon ignited a new wildfire near Red Mountain in the Trout Creek Mountains area. The “Water Tower” fire received quick attention from engine crews soon after its start and reportedly laid down until sporadic winds brought the fire back to life around 11:00 p.m. This morning, crews estimate the fire to be approximately 3-500 acres. At least three area ranches with structures are within the fire vicinity though not immediately threatened. Livestock grazing allotments, inaccessible terrain, private inholdings and Sage Grouse core habitat are also concerns. With high fuel loads of grass and brush from two seasons of productive growth and low winter snow pack, fire spread could be rapid and intense in this area. Longer burn periods and elevated fire intensity extending after sunrise can also be expected. Five Single Engine Air Tankers, three helicopters, numerous engines and dozers will support the suppression operation throughout the day. Heavy air tankers have been ordered for availability if needed. Updated information on the Water Tower fire will be released as conditions change and improve. The High Desert Type 3 Incident Management (Toney) is assigned to the Water Tower fire. The Miller Homestead fire, which started Sunday, July 8, is currently estimated at 95 percent contained. Dry peat soils in the Malheur National Wildlife Refuge continue to burn below the surface, presenting a unique challenge for firefighters.

  • Brief History of Carson City, Heart of Nevada
    Brief History of Carson City, Heart of Nevada For nearly 4,000 years before the coming of white settlers, the Washoe Indians occupied the land along the Sierra Nevada Mountain Range that borders Nevada and California. In 1851 a group of prospectors decided to look for gold in the area that is now Carson City. Unsuccessful in that attempt, they opened up a trading post called Eagle Station on the Overland Stagecoach route. It was used by wagon trains of people moving westward. The surrounding area came to be called Eagle Ranch, and the surrounding meadows as Eagle Valley. In time, a number of scattered settlements grew up in the area and the Eagle Ranch became its social center. As a growing number of white settlers came to the area and began to develop the valleys and mountains of the Sierra Nevada, the Washoe people who for so long had occupied the area were overwhelmed. Although lands were allotted to individual Indians by the federal government starting in the 1880s, they did not offer sufficient water. As a result, the Washoe tended to set up camp at the edges of white settlements and ranches in order to work for food. It would not be until the twentieth century that parcels of reservation land were established for them. Many of the earliest settlers in the Carson City area were Mormons led to Eagle Valley by Colonel John Reese. When the Mormons were summoned to Salt Lake City, Utah, by their leader, Brigham Young, many sold their land for a small amount to area resident John Mankin, who later laid claim to the entire Eagle Valley.

    Volume 8 Number 8 30 December 2020 The Taxonomic Report OF THE INTERNATIONAL LEPIDOPTERA SURVEY ISSN 2643-4776 (print) / ISSN 2643-4806 (online) Review of the Speyeria egleis complex in Montana, with the description of two new subspecies (Lepidoptera: Nymphalidae: Heliconiinae) Steve Kohler 2617 Glen Drive Missoula, MT 59804 ABSTRACT: Four phenotypically and geographically distinct sets of populations of Speyeria egleis are identified in Montana. Two new subspecies are named from northwestern and northcentral Montana. Two existing names are recognized (S. e. macdunnoughi from southwestern Montana, southeastern Idaho and northwestern Wyoming, and S. e. albrighti from central Montana. S. e. near macdunnoughi from Oregon and Washington is discussed. Additional key words: Island ranges, Sweet Grass Hills, Morrell Mountain, Highwood Mountains. ZooBank registration: urn:lsid:zoobank.org:pub:94D912CC-72BA-42EA-A14E-E0F51E1CD498 INTRODUCTION At the present time, thirteen described subspecies of Speyeria egleis (Behr, 1862) are recognized in North America (Pelham 2020). Of these, two occur in Montana, S. e. macdunnoughi (Gunder, 1932) and S. e albrighti (Gunder, 1932). Historically, all Montana egleis populations with a brownish colored under hindwing disc have been assigned to macdunnoughi and all populations with an olive-green colored under hindwing disc have been assigned to albrighti (Ferris and Brown 1981; Kohler 1980). During the course of my study of Montana butterflies, I have identified at least four distinct sets of populations which can be phenotypically and geographically segregated. The purpose of this paper is to define the characters of these four distinctive populations and to describe two new subspecies. DISCUSSION In this study, the two current subspecies of S.
