Geologic Map of the Ketchikan and Prince Rupert Quadrangles, Southeastern Alaska
DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP I-1807 U.S. GEOLOGICAL SURVEY GEOLOGIC MAP OF THE KETCHIKAN AND PRINCE RUPERT QUADRANGLES, SOUTHEASTERN ALASKA By Henry C. Berg, Raymond L. Elliott, and Richard D. Koch INTRODUCTION This pamphlet and accompanying map sheet describe the geology of the Ketchikan and Prince Rupert quadrangles in southeastern Alaska (fig. 1). The report is chiefly the result of a reconnaissance investigation of the geology and mineral re sources of the quadrangles by the U.S. Geological Survey dur ing 1975-1977 (Berg, 1982; Berg and others, 1978 a, b), but it also incorporates the results of earlier work and of more re cent reconnaissance and topical geologic studies in the area (fig. 2). We gratefully acknowledge the dedicated pioneering photointerpretive studies by the late William H. (Hank) Con don, who compiled the first 1:250,000-scale reconnaissance geologic map (unpublished) of the Ketchikan quadrangle in the 1950's and who introduced the senior author to the study 130' area in 1956. 57'L__r-'-'~~~;:::::::,~~.::::r----, Classification and nomenclature in this report mainly fol low those of Turner (1981) for metamorphic rocks, Turner and Verhoogen (1960) for plutonic rocks, and Williams and others (1982) for sedimentary rocks and extrusive igneous rocks. Throughout this report we assign metamorphic ages to various rock units and emplacement ages to plutons largely on the basis of potassium-argon (K-Ar) and lead-uranium (Pb-U) (zircon) isotopic studies of rocks in the Ketchikan and Prince Rupert quadrangles (table 1) and in adjacent areas. Most of the isotopic studies were conducted in conjunction with recon naissance geologic and mineral resource investigations and re 0 100 200 KILOMETER sulted in the valuable preliminary data that we cite throughout our report. -

Confirmed Breeding of the Greater Yellowlegs in Southern Southeast Alaska Andrew W
NOTES CONFIRMED BREEDING OF THE GREATER YELLOWLEGS IN SOUTHERN SOUTHEAST ALASKA ANDREW W. PISTON, P. O. Box 1116, Ward Cove, Alaska 99928 STEVEN C. HEINL, P. O. Box 23101, Ketchikan, Alaska 99901 The known breeding range of the Greater Yellowlegs (Tringa melanoleuca) extends from Newfoundland, Labrador, and Nova Scotia west to east-central British Columbia and southern Alaska (AOU 1998). In Alaska, this species nests from Etolin and Kupre- anof islands in southeast Alaska north and west to Kodiak Island, the Alaska Peninsula, and the western Yukon River valley (Elphick and Tibbitts 1998). The breeding status of this species along the coast of northern British Columbia (Campbell et al. 1990) and southern southeast Alaska has not been determined (Elphick and Tibbitts 1998), primarily due to a lack of observers. In June 1909, Swarth (1911) reported seeing birds which he thought might be nesting on Duke Island, one of the southernmost islands in southeast Alaska, but he provided few details. Although the Greater Yellowlegs breeds in the central interior of British Columbia, Campbell et al. (1990) mentioned only one possible breeding record from coastal British Columbia, at Porcher Island, which they excluded because of a lack of evidence. Breeding records for Etolin and Kupreanof islands (Willett 1921, Gabrielson and Lincoln 1959), 150 km north of the U.S.–Canada border, are the southernmost ones published for southeast Alaska. Here we extend the confirmed breeding range of the Greater Yellowlegs into southernmost southeast Alaska to 54° 40' N latitude (Figure 1) and lend support to undocumented breeding reports from the adjacent coast of northwestern British Columbia. -
Chapter 3 Affected Environment
Gravina Access Project Draft Supplemental Environmental Impact Statement Chapter 3 Affected Environment This page intentionally left blank. Gravina Access Project Draft SEIS Affected Environment 3.0 AFFECTED ENVIRONMENT This chapter inventories and characterizes the economic, environmental, and cultural resources in the Gravina Access Project area that could be affected by the proposed project alternatives. This information is drawn from the data, documents, and plans published by a variety of local, state, and governmental agencies, and project-specific technical studies completed by HDR Alaska, Inc., and its affiliates on behalf of DOT&PF, as listed in the References section. All figures referenced in this chapter may be found at the end of the chapter. 3.1 Land Use 3.1.1 Current Land Use This section describes the current land ownership, land uses, and zoning within the project area on Revillagigedo, Pennock, and Gravina islands. General land ownership within the project area is presented below in Table 3.1 and shown in Figure 3.1; land uses are listed in Table 3.2 and shown in Figure 3.2; and project area zoning is summarized in Table 3.3 and shown in Figure 3.3. Native lands in Alaska are typically held by regional and village Native corporations formed by the Alaska Native Claims Settlement Act and are considered to be privately owned. Native Village Corporations have been making selections from federal lands over several decades, and some of these selections are still underway in Southeast Alaska. Native Village Corporations have also purchased commercial properties and run businesses in many communities, including Ketchikan. -

Geotechnical Report Gravina Access Project
Phase I Geotechnical Report Gravina Access Project Agreement No: 36893013 DOT&PF Project No: 67698 Federal Project No: ACHP-0922(5) Prepared for: State of Alaska Department of Transportation and Public Facilities 6860 Glacier Highway Juneau, Alaska 99801 Prepared by: Shannon & Wilson Under contract to: HDR Alaska, Inc. 712 West 12th St. Juneau, AK 99801 May 2000 Phase I Geotechnical Report, Gravina Access Project EXECUTIVE SUMMARY This preliminary geotechnical report presents the results of our review of existing literature and limited geotechnical engineering analysis for the Gravina Access Project, Ketchikan, Alaska. The purpose of the literature review was to identify the likely subsurface conditions at various potential water crossing locations. Preliminary geotechnical engineering studies were then conducted to develop conceptual foundation design recommendations and assist the design team in narrowing the crossing alternatives to the more promising alignments. Because most existing data is near the shoreline and there is essentially no drilling data in the middle or deep parts of the Tongass Narrows, the recommendations we have provided should be recognized as being conceptual for use in planning and feasibility studies for the project. For this preliminary study, four subsurface cross-sections were developed to represent our rough estimate of the anticipated depths and possible subsurface conditions that could be encountered in the various water crossing corridors. The sections are situated to the North, directly across from downtown Ketchikan and to the south crossing Pennock Island where two water crossing are required to complete the hard link. These profiles are conceptual at this stage and will have to be refined with follow-on exploratory studies. -

Draft Archeological Reconnaissance Survey
GRAVINA ACCESS PROJECT Draft Archeological Reconnaissance Survey Agreement 36893013 DOT&PF Project 67698 Federal Project ACHP-0922(5) Prepared for STATE OF ALASKA Department of Transporation and Public Facilities 6860 Glacier Highway Juneua, Alaska 99801 Prepared by Michael R. Yarborough Cultural Resource Consultants Anchorage, Alaska In association with HDR Alaska, Inc. 712 West 12th Street Juneau, AK 99801 NOVEMBER 2001 Archeological Reconnaissance Survey Report I-Executive Summary Archeological and historical sites are sensitive to physical disturbance and could be affected by development associated with the Gravina Access Project, which is intended to improve transportation access between Ketchikan on Revillagigedo Island and Gravina Island. A reconnaissance level field survey of the project area was conducted during May 2001 to evaluate the cultural resources potential of the seven alternatives currently under consideration. The principal impact issue for cultural resources is the loss or degradation of prehistoric and historic archaeological sites, either through direct disturbance during construction or indirect disturbance due to changes in public accessibility. Alternatives F3, G2, and G3 are the most archaeologically sensitive of the seven alternatives currently under consideration. The northern shores of both Pennock and Gravina Islands along Alternative F3 were heavily occupied during the first half of the twentieth century. These are areas of both known historic sites and high archeological potential. The proposed ferry terminals for Alternatives G2 and G3 along the Ketchikan waterfront are in areas with little archeological potential. However, the ferry landings on Gravina Island, near Lewis Point and southeast of East Clump bight, respectively, are in areas of both known historic and prehistoric sites, and high archeological potential.
