Introduction
How to Use This Guidebook
THE OVERVIEW MAP AND OVERVIEW MAP KEY
USE THE OVERVIEW MAP on the inside front cover to pinpoint the exact location of each hike’s primary trailhead. Hike numbers appear on the overview map, on the map key facing the overview map, in the table of contents, at the beginning of each hike profile, and at the top of each trail map.
The book is organized by region as indicated in the table of contents, and the hikes within each region are noted as day hikes, overnight hikes, or a combination of the two. They are also labeled on the Table of Contents as out-and-back, loop, or point-to-point routes. A legend on the inside back cover explains the symbols found on the trail maps.
TRAIL MAPS
Each hike contains a detailed map that shows the trailhead, the route, significant features, facilities, and landmarks such as creeks, overlooks, and peaks. I gathered map data by carrying a Garmin eTrex Legend and Garmin eTrex Venture HC while hiking. This data was downloaded into a digital mapping program, TOPO USA, and then processed by an expert cartographer to produce the highly accurate maps in this book. Each trailhead’s GPS coordinates are included with each profile (see page). In each hike’s summary information, I also recommend a commercially available, color map that you may find useful, particularly for backpacking or cross-country trekking.

ELEVATION PROFILES
Corresponding directly to the trail map, each hike contains an elevation profile that enables you to easily visualize how the trail rises and falls. Key points along the way are labeled. Note the number of feet between each tick mark on the vertical axis (the height scale). To keep flat hikes from looking steep and steep hikes from appearing flat, height scales are included to provide an accurate assessment of climbing difficulty.
GPS TRAILHEAD COORDINATES
To collect accurate map data, I carried a handheld GPS unit (Garmin eTrex series) as I scouted. The data collected was then downloaded and plotted onto a digital U.S. Geological Survey (USGS) topo map. In addition to rendering highly specific trail outlines, this book also includes the GPS coordinates for each trailhead in two formats: latitude–longitude and Universal Transverse Mercator (UTM). Latitude coordinates tell you where you are by locating points west of the zero-degree meridian line that passes through Greenwich; longitude coordinates do so by locating points north or south of the zero-degree line that belts the Earth, aka the equator.
Topographic maps show latitude and longitude data as well as UTM grid lines. Known as UTM coordinates, the numbers index a specific point using a grid method. The survey datum used to arrive at the coordinates in this book is WGS84 (versus NAD27 or WGS83). For readers who own a GPS unit, whether handheld or onboard a vehicle, the latitude–longitude or UTM coordinates provided on the first page of each hike may be entered into the GPS unit. Just make sure your GPS unit is set to navigate using WGS84 datum. Now you can navigate directly to the trailhead.
Most trailheads, which begin in parking areas, can be reached by car, but some hikes still require a short walk to reach the trailhead from a parking area. In those cases, a handheld unit is necessary to continue the GPS navigation process. That said, however, readers can easily access all trailheads in this book by using the directions given, the overview map, and the trail map, which shows at least one major road leading into the area. But for those who enjoy using the latest GPS technology to navigate, the necessary data has been provided. A brief explanation of the UTM coordinates from Warner Valley Road to Terminal Geyser follows:
| UTM Zone (WGS84) | 10T |
| Easting | 0635907 |
| Northing | 4478154 |
The zone number (10) refers to one of the 60 vertical zones of the UTM projection. Each zone is 6 degrees wide. The zone letter (T) refers to one of the 20 horizontal UTM zones that span from 80 degrees south to 84 degrees north. The easting number (0635907) indicates in meters how far east or west a point is from the central meridian of the zone. Increasing easting coordinates on a topo map or on your GPS screen indicate that you are moving east; decreasing easting coordinates indicate that you are moving west. The northing number (4478154) shows in meters how far you are from the equator. Above and below the equator, increasing northing coordinates indicate that you are traveling north; decreasing northing coordinates indicate that you are traveling south.

THE HIKE PROFILE
In addition to maps, each hike contains a concise but informative narrative of the hike from beginning to end. This descriptive text is enhanced with at-a-glance ratings and information, GPS-based trailhead coordinates, and accurate driving directions that lead you from a major road to the parking area most convenient to the trailhead.
At the beginning of each hike is a box that gives hikers quick access to pertinent information: quality of scenery, condition of the trail, the hike’s appropriateness for children, the difficulty of the hike, the degree of solitude expected, hike distance, approximate hiking time, and outstanding highlights of the trip. The first five categories are rated using a five-star system. Below is an example:
