Anchorage, Alaska 1982 Map and table describing fossil collections and related samples in the Ketchikan and Prince Rupert quadrangles, southeastern Alaska by Henry C. Berg and Edwin L. Cruz INTRODUCTION This report consists of a map and companion table describing (a) fossil collections that have been made in the Ketchikan and Prince Rupert quadrangles east of Clarence Strait, and (b) samples collected for fossil (mainly ) determinations, whether or not they actually yielded or other fossils. The purpose of the report is to summarize in a single publication information about fossils gathered in the area by numerous workers since before 1900; some of this information has not previously been publically available. The report supplements published geologic maps of Annette and Gravina Islands (Berg, 1972, 1973) and of the Ketchikan and Prince Rupert quadrangles (Berg and others, 1978), and is one of a series of reports stemming from geological and mineral resource investigations of the area conducted under the Alaska Mineral Resource Assessment Program (AMRAP) (Berg, 1982). Sources of information compiled for this report mainly are books and maps published by the U.S. Geological Survey (USGS). These are cited in the table and are listed at the end of this introduction. In most cases, the cited work contains additional information about the geology, stratigraphy, or fauna at the site. Sources of unpublished data include formal and informal reports by USGS paleontologists describing some of the fossil collections, and notebooks and maps of USGS workers conducting geological and mineral resource studies in the area. The map shows the sites of approximately 150 fossil localities plotted at two topographic map scales. The larger scale map covers the Gravina-Annette- Hotspur Islands area, which contains most of the fossil occurrences known in the Ketchikan and Prince Rupert quadrangles. The other map encompasses both quadrangles and shows the sites of the dozen-odd fossil occurrences known outside the Gravina-Annette-Hotspur area. This map also is a generalized geologic map showing the distribution of major rock units in the quadrangles, and is the reference for the map units listed in the first column of the table. Data for the geologic map are generalized from several USGS publications that describe the geology in more detail (Berg, 1972, 1973, 1982; Berg and others, 1977, 1978). The table summarizes information available about each fossil occurrence or related sample and includes, insofar as is known: geologic map unit; lithology; collector, year, and (when appropriate) USGS Museum collection number; names and ages of fossils; name of the person who identified the fossils; and citations of published references or other sources of data. Presentation of data: Some of the most complete fossil collections and related descriptions were made by early workers when many of the sites were accessible by mining or logging roads. The table thus lists fossil collections in approximate chronological order, starting with the earliest collections reported in the area. On the other hand, lack of adequate maps prevented these early workers from recording the exact locations of their collections, and many of their sites are only approximately located on the maps in this report. More than one number at a site indicates that it was examined more than once, and these numbers are also in approximate chronological order. Presentation of data: Some of the most complete fossil collections and related descriptions were made by early workers when many of the sites were accessible by mining or logging roads. The table thus lists collections in approximate chronological order, starting with the earliest collections reported in the area. Lack of adequate maps prevented many of these early workers from recording the exact locations of their collections, and many of their sites are only approximately located on the maps in this report. Such approximately located sites are indicated by the symbol (A) in the second column of the table. More than one number at a site indicates that it was examined more than once, and these numbers are also in approximate chronological order. Fossil identification and nomenclature: Except for omitting customary italics for generic and specific names, this report presents names of fossils identified in the collections exactly as originally published or otherwise reported. Subsequent taxonomic revisions may have invalidated some reported names. Lithology: To conserve'space, abbreviations are used in the left column of the table to summarize the lithology at each occurrence. A key to these lithologic abbreviations, together with examples of how to use them, follows.

KEY TO LITHOLOGIC ABBREVIATIONS USED IN THE LEFT COLUMN OF THE TABLE ar: argillite, argillaceous Is: limestone cc: calcareous mb: marble eg: conglomerate ph: phyllite, phyllitic cl: clast py: pyrite, pyritic en: concretion, concretionary sc: schist, schistose dt: dolomite, dolomitic si: slate, slaty gr: graphitic ss: sandstone, sandy gt: grit, .gritty st: siltstone, silty gw: graywacke tf: tuff, tuffaceous li: lithographic

2/ Information about conflicting or ambiguous reports of ages is given under "Remarks". Term "indeterminate" Indicates that: (a) fossil material in collection was insufficient, too wide-ranging, or too poorly preserved to determine its age; (b) foasll remains were noted in outcrop but could not be collected for formal identification; or (c) organic origin of material is doubtful.

3/ Unless otherwise noted, all fossil Identifications are by U.S. Geological Survey paleontologists or geologists.

4/ Numerous collections are described in more than one publication. References cited contain either earliest or most complete descriptions. Summary descriptions of fossils collected by early (pre-1929) workers in the Ketchikan and Prince Rupert quadrangles are in Martin (1926) and Buddington and Chapln (1929).

In 1979 a carbonate sample (no. 149) collected at this site yielded an Upper Trissslc conodont . This determination, coupled with other samples (nos. 150, 151) and restudy of geologic relations of this unit resulted In assigning it sn Upper Triassic age (Berg, 1982, p. 5-7). If the earlier tentative Paleozoic determinations are correct, this apparently con­ tradictory occurrence may result from processes similar to those described under "Remarks" at locality 39.
