Me and my GPS pointing the way on what was then Squaw Mountain...

NOTE: LIDAR (Light Detection and Ranging) was put into use many decades after I started hiking and climbing. LIDAR is a more accurate way of measuring the Earth's surface and, as such, has changed what was believed to be the elevation of many mountains and highpoints. As a result, the "prominence" (at least 300 feet above a connecting saddle) of many mountains has changed along with their elevations. A personal example, for me, is Republican Mountain - a previously "unranked" 12er near Silver Plume that I climbed in 2022 after learning that LIDAR had determined it now had 312 feet of prominence. Peak 8, near Breckenridge is another personal example of change brought on by LIDAR. When I originally climbed Peak 8 I believed it to be a 12er, only to learn later that it's actual elevation is 13,005 feet! So, in summary, many of the elevations you see on my pages may not (yet) be accurate - requiring an update someday in the future as time permits!

Segal's Law: A man with a watch knows what time it is. A man with two watches is never sure.

I included this adage to my page during the summer of 2023 when I completed a number of tests and experiments with various GPS devices (GPSMap64s, my cellphone, and the cellphones of various friends) and software (CalTopo, AllTrails, GPS Visualizer, Garmin, and others...). What I found was that no two devices (or applications) ever matched as far as the distance and elevation gain that I experienced on a route. In fact, some of them were as much as ten percent different - even on trips less than 10 kilometres in lenghth that had only a few hundred feet of gain. In conclusion, I don't have a clue has to how one can obtain an "exact" reading for any hike or climb. Other than maybe scrutinizing a topographical map. But, even then, the distance between contour lines can distort that data as well. So, who know??!! - Roger J. Wendell, August 2023

Definitions, Descriptions, and Cautionary Notes:

Jolie's waypoint tattoo...

A Global Positioning Satellite (GPS) receiver tunes into the microwave signals broadcast by 24 satellites that each orbit the Earth every 12 hours. This "Constellation" of two dozen navigational satellites is controlled by the United States Department of Defense and operated by the U.S. Military (This is an unfortunate situation in that not only is the American military used for suspect purposes but they've also been known to intentionally shut the GPS system down over certain parts of the planet!!). There are six orbital planes (each with four satellites) spaced equally at 60 degrees apart and inclined at abut 55 degrees with respect to the equatorial plane. In plain English this means you can usually count on your receiver "seeing" about five to eight of these satellites at anyone time - depending on where you're located, of course... In August, 1998 I ended up with my first GPS - A Garmin GPS 12XL Personal Navigator. I won the device as a door prize at an amateur radio "swapfest" and it served me well until I lost it in Argentina in 2004... So, in July, 2004 I purchased a Garmin eTrex Vista Personal Navigator. I still don't rely on a GPS completely, for navigation, because I can drop and break it, the batteries die, I can (and have!) lose it, the military can turn it off (as mentioned above), and bad weather and canyon walls can block its signal reception. [Ed. Note: As recently as August 2011 there was still serious concern that solar flares would disrupte the world's GPS devices...]. That being said, a GPS is still a fun little devices to play with so I usually don't leave home without one!

Storing "Waypoints" is one of the features I use most on my GPS. The owner's manual for my GPX 12XL simply defined a waypont as "A specific location saved in the receiver's memory" (bottom of page 3 in the glossary). The waypoints I store are usually the location of a mountain top I've visited, a friend's home, a trailhead, or even the rooftop of the Dalai Lama's Potala Palace in Tibet! Anyway, I'll list my collection of waypoints on this and other pages as time permits. And, as a safety note, I ask that you do not rely on my waypoints for anything - I list 'em here for personal use and cannot verify their accuracy!   [Ed. Note: After the second decade of the second millennium I started using GPS apps on a smart phone but wasn't overly impressed. I think their antennas are lacking (they're internal antennas) so I eventually settled on a Garmin GPSMap 64s - checking the Garmin against maps and other standards I found it to be much more reliable than my cellphone and earlier GPS models. But, that's just my own opinion - please do your own research before relying on any navigational device!]

Andrew Skurka on GPS Units

From his book, The Ultimate Hiker's Gear Guide (Tools & Techniques to Hit the Trail) Second Edition (pp. 132-133)

"Many people seem surprised that I can expertly navigate through the wilderness without relying on a GPS (which stands for 'global positioning system') unit. These devices can: Show my exact location, to an accuracy of a few feet; Calculate the distance and direction to key landmarks, like my car, a hot fishing hole, or a trail junction; Determine how far, how fast, and in which direction I've hiked; and Record a track on my route that I can share or use when I get home." But these functions do not make a GPS a killer app. I can do exactly the same thing with a topo graphic map, altimeter watch, magnetic compass, and pen. Furthermore, a GPS cannot replace map reading skills, especially for off-trail navigation. A GPS can tell me the straight-line distance and direction to a landmark, but it cannot tell me the line of least resistance to get there. That straight line might take me through the thickest brush, into a deep canyon, or across the river at its deepest point." My stance on GPS units has evolved since I wrote the first edition of this guide. I now consider it an ace in my sleeve for when my standard tools reach their limits. First, on a GPS I can store maps and imagery of the areas surrounding my intended route, for which I don't have paper maps. Second, a GPS offers unrivaled speed and certainty."

GPS and Time

The GPS system relies on precise time, both from ground and satellite units, to calculate your exact location in three dimensions. Because of Special Relativity the clocks on the satellites slow down due to their speed. The clocks on the ground slow down even more due to the Earth's gravity well. Therefore, the clocks in oribit must be slowed down, slightly, to match the GPS clocks on Earth. The processor in your gps unit takes all these things into account when it makes its calculations for your speed and elevation here on Earth.

To calculate elevation, a GPS typically relies on a standard geoid model. The geoid is the equipotential surface that would coincide with the mean ocean surface of the Earth if the oceans and atmosphere were in equilibrium and at rest relative to the planet's rotation - kind of like a surface of constant gravity if the Earth was entirely ocean. The ellipsoid is an arbitrary reference surface that is an approximation of the Earth's shape, which is basically a sphere slightly "flattened" at the poles.

"The procedure of geodetic leveling provides a height that is commonly known as a height above mean sea level. In this process, level differences, which express the alignment of a level bubble, are combined with surface gravity readings to obtain final values. Formally, heights from geodetic leveling are known as orthometric heights." "It should come as no surprise that orthometric heights will reflect local variations in gravity as well as changes in topography. The reference surface for orthometric heights is a level surface of the Earth that is closely associated with mean sea level on a global basis. This particular level surface is called the geoid. Orthometric heights are the vertical distance from the geoid to the surface of the Earth. And, by convention, the sign is considered positive as one moves radially outward."

"GPS, on the other hand, produces a much different kind of height. Whether one uses point, differential, or differenced carrier phase positioning, one obtains a set of XYZ coordinates that depend upon locations of base stations and satellite positions. These three-dimensional, geometric relationships, in contrast to geodetic leveling, do not depend on local gravity variations. Since XYZ coordinates do not directly express the notion of height, it is necessary to transform them into a different coordinate system. Typically, XYZ are transformed into geodetic latitude, longitude and ellipsoidal height. This transformation is performed using a very simple, two-parameter, model of the Earth: the ellipsoid."

In February, 2009 my friend Jeff was shopping around for a GPS receiver so we both looked into the matter a little more deeply. Again, I'm not an expert in navigation so I strongly recommend you take a class and study the matter before you rely on your GPS for survival. Anyway, a decade ago I was using the term "breadcrumb" track to describe the electronic memory of where my GPS had been tracking my travel. I think now, in the last part of this decade, they're starting to use the term, "tracklog" to describe the same thing. www.gpsinformation.net describes it this way on one of their web pages (they changed their domain name so I don't know if you'll be able to find this exact wording again or not): "Tracklogs are basically the equivalent of dropping breadcrumbs so that you can retrace your steps. They provide a history of your travels." "A tracklog can be automatically turned into a trackback route to lead you back to your starting point. In addition they can be downloaded to a computer and used to 'playback' your travel over the top of a mapping program so that you can show someone exactly where you went. Since time is also recorded the computer program could also indicate the speed of your travel and compute the length of the trip as recorded in the tracklog. Tracklogs are capable of recording breaks in the log where you moved between fixes or where the unit may have lost a lock. Tracklogs are displayed on the map screen along with visual indications of waypoint locations and your current position." - Roger J. Wendell February 2009 - Golden, Colorado

Maidenhead Grid Locator System
and Amateur Radio

Me, WBØJNR

Amateur Radio operators often use the Maidenhead Locator System when providing their QTH (Location) during a communications exchange. The grid locator is a convenient way of expressing location (and aiming antennas!) on VHF, UHF, and the microwave bands. However, "grid squares" are also convenient for QRP (low power transmissions) operators interested in calculating miles-per-watt statistics on the HF bands. "Grid squares" are like rectangles and are a way of dividing up the surface of the Earth. Grid squares are a quick way of describing your general location anywhere on the Earth in a manner that is easy to communicate over the air. The Maidenhead Locator System is named after the town outside of London where it was first conceived, in 1980, at a meeting of European amateur radio operators involved in VHF communications. A grid square measures 1° latitude by 2° longitude and measures approximately 70 by 100 miles (113 by 161 kilometres) in the continental United States. A grid square is indicated by two letters (the field) and two numbers (the square), as in DM79, the grid square within which Denver area amateur radio operators reside here in Colorado. Grid Squares are further divided into sub squares which are designated by the addition of two letters after the grid square. For example, one of the aforementioned Denver Area amateur radio operators might be located in grid square DM79op - an area called "Smoky Hill" in southeast Aurora, Colorado.
