Mining historian Kerby Jackson introduces us to a classic mining
work in this important re-issue of Geological Survey Bulletin 1290.
Unavailable since 1971, this publication was originally compiled by
Preston E. Hotz and includes details on the lode mining districts
of Oregon and California's Klamath Mountains. Included are details
on the geology, history and important lode mines of the French
Gulch, Deadwood, Whiskeytown, Shasta, Redding, Muletown, South
Fork, Old Diggings, Dog Creek (Delta), Bully Choop (Indian Creek),
Harrison Gulch, Hayfork, Minersville, Trinity Center, Canyon Creek,
East Fork, New River, Denny, Liberty (Black Bear), Cecilville,
Callahan, Yreka, Fort Jones and Happy Camp mining districts in
California, as well as the Ashland, Rogue River, Applegate,
Illinois River, Takilma, Greenback, Galice, Silver Peak, Myrtle
Creek and Mule Creek districts of South Western Oregon. Also
included are insights into the mineralization and other
characteristics of this important mining region. Note: This edition
is a perfect facsimile of the original edition and is not set in a
modern typeface. As such, some type characters and images might

Water-resources data for the 2004 water year for North Carolina
consist of records of stage, discharge, water quality for streams;
stage and contents for lakes and reservoirs; precipitation; and
ground-water levels and water quality of ground water. Volume 1
contains discharge records for 217 gaging stations; stage and
contents for 58 lakes and reservoirs; stage only records for 22
gaging stations; elevations for 9 stations; water quality for 39
gaging stations and 5 miscellaneous sites, and continuous water
quality for 35 sites; and continuous precipitation at 127 sites.
Volume 2 contains ground-water-level data from 161 observation
wells, ground-water-quality data from 38 wells, continuous water
quality for 7 sites and continuous precipitation at 7 sites.
Additional water data were collected at 51 sites not involved in
the systematic data-collection program, and are published as
miscellaneous measurements in Volume 1. The collection of
water-resources data in North Carolina is a part of the National
Water-Data System operated by the U.S. Geological Survey in
cooperation with State, municipal, and Federal agencies.
Weather and climate are strong drivers of population dynamics,
plant and animal spatial distributions, community interactions, and
ecosystem states. Information on local weather and climate is
crucial in interpreting trends and patterns in the natural
environment for resource management, research, and visitor
enjoyment. This document describes the weather and climate
monitoring program at the Channel Islands National Park (fig. 1),
initiated in the 1990s. Manual and automated stations, which
continue to evolve as technology changes, are being used for this
program. The document reviews the history of weather data
collection on each of the five Channel Islands National Park
islands, presents program administrative structure, and provides an
overview of procedures for data collection, archival, retrieval,
and reporting. This program overview is accompanied by the 'Channel
Islands National Park Remote Automated Weather Station Field
Handbook' and the 'Channel Islands National Park Ranger Weather
Station Field Handbook'. These Handbooks are maintained separately
at the Channel Island National Park as 'live documents' that are
updated as needed to provide a current working manual of weather
and climate monitoring procedures. They are available on request
from the Weather Program Manager (Channel Islands National Park,
1901 Spinnaker Dr., Ventura, CA 93001; 805.658.5700). The two Field
Handbooks describe in detail protocols for managing the four remote
automated weather stations (RAWS) and the seven manual Ranger
Weather Stations on the islands, including standard operating
procedures for equipment maintenance and calibration; manufacturer
operating manuals; data retrieval and archiving; metada collection
and archival; and local, agency, and vendor contracts.
