GPS Tips - Before You Go

A GPS training web site that I keep my eye on is GPSTraining.  These folks have a lot of great info on how to use your GPS receiver.

Before you go - our top tips.
1) Clear Trip Data at the point you start your trip – to ensure that your trip data relates only to your current trip you must clear your trip data at the start of your trip (not at home then drive to the start of your trip) as the moment your clear the trip computer starts logging data again and could include trip & track data that includes your journey from home to the start of your trip.
In GPS > from the Main Menu > select Setup > Reset > Reset Trip Data > Reset

2) Clear Track Data – like trip data once cleared track data immediately re-commences if the GPS is active (logged onto satellites) so the golden rule is to clear track data at the start of your trip and save at the end of your trip this way your track log will become the most accurate record of your trip and can be imported to your favourite computer software to review your performance.

Power For Your GPS

In 13 years of teaching GPS classes I have had very, very few reports of a GPS breaking or failing electronically but I do hear about battery power draining at the worst time.

I’d offer a few suggestions:

•  Batteries will generally last for a reported 20 hours of continuous use; more on that shortly.  If you just turn it on, mark a waypoint and turn the receiver off the batteries will last you most of the hunting season.

• I like the Duracell and COSTCO alkaline batteries. 

•  If your GPS can use Lithium batteries that is great.  They are more expensive but they last longer and work better in cold temperatures; check your owner’s manual. 

•  I keep my GPS powered up all day when in the backcountry.  I like to download my track and waypoint data at the end of a hunt to my Terrain Navigator software. (This gives me the best historical record of my outing.)  I dump the batteries back at camp each evening.  Usually my batteries become drained after a full day and it just simpler to change them out as I get my gear ready for the next day’s hunt.  I don’t want to worry about dead batteries during the next day’s hunt.

• Keep a spare set of AA batteries in your pack.  I recommend storing the batteries in the paper box that the Duracell’s come in or in the plastic wrapper that the COSTCO batteries come in.

•  I keep fresh batteries in my GPS all the time.  I am reading more frequently that this is no longer needed.  That said, because of my SAR responsibilities and the frequency of my trips, fresh batteries are always loaded.  It’s my personal preference that “works for me.”

• I don’t have a baseline for rechargeable batteries.  My suggestion would be to keep extra’s on hand and really “wring them out” over a full day to see how well they work. Do this before your trip afield.   Remember, it has to work for you.

•  Features such as the backlight, audible tones and electronic compasses drain a set of batteries.  On many models the electronic compass can be turned off by pressing and holding down the page button.  Manage your power needs.

A fully charged GPS is a wonderful tool that complements your backcountry experience.  Remember, even though you have the latest and best receiver, you always take that map and compass on every trip. 

Orienting a Topograhic Map

“Orienting the map visually (or with the greater precision afforded by a compass) connects hikers to their surroundings, helps them see the larger picture, and their place in it.  Hikers who nurture this habit are usually both safer and more appreciative of the places they’re exploring.”

From the book Staying Found by June Fleming

Orienting a map is a starting point to identify where I am, where I want to go and where I have been.

 I orient my topographic map (topo) before I leave the trail head and at regular intervals during a hike.

It is a process where I involve both map and compass.  Of course, orienting a map can be done without a compass and done visually.  I find using a compass takes just a tad more time and the more hands on time with the compass the better. 

Correctly orienting my map allows me to get “dialed in” to my surroundings.  It is a process where I align the map, compass and GPS to the terrain before me.
This orientation procedure is a great opportunity to involve young people in backcountry navigation.  Give them a quick review of topo basics and your plan before starting out.

A topo is your key to the backcountry.  It unlocks the critical information regarding sources of water, woodlands, trails, roads, grid information and elevation.  I use a US Geologic Survey (USGS) map at the scale of the map should be 1:24,000.  (National Geographic has superb topos of the National Parks and you may find quality maps of this scale of the area you will travel in.)  Quality outdoor, printing and mapping stores will have such a map available.  While you get comfortable with a hard copy paper map, experiment with map software (www.mytopo.com) or internet sites that offer free maps (www.mappingsupport.com.)  Aerial imagery such as Google Earth (www.google.com/earth/index.html) compliments the topo.
A great reference for navigating a topo is the book “Staying Found” by June Fleming.   It’s available at many bookstores and is likely at the local library.

Moving on to the compass, I recommend backcountry travelers use a declination adjustable compass such as the Brunton 8010G, Silva Ranger or a Suunto M2. Declination is the angular difference between true north and magnetic north.    A declination adjustable compass keeps things simple.  For example, a compass adjusted to degrees true will match the same orientation as the map; all in degrees true.

Declination data can be found in the diagram at the bottom of the USGS topo, (on some commercially produced maps you really have to look for this information.)  I recommend that map declination information be verified at www.magnetic-declination.com.   This is essential in the Pacific Northwest where maps are notoriously out of date in terms of road, city and some trail data.

Using the manufacturer’s instructions, I adjust the compass for declination.  If your declination is east, observe the orienting arrow (on a Brunton 8010G) rotate in a clockwise direction.  If declination is westerly adjust counter clockwise.

To correctly orient my topo, I lay the baseplate (edge of the compass) on the border of the topo; below.  Use the map’s eastern or western border.  I then turn my body (while holding the map and compass) until the map points to true north; the red magnetic needle will be on top of the orienting arrow.  (Remember, maps are laid out in degrees true.) Now both the topo and compass will be oriented to true north.

At this point, I evaluate the topographic features of the map and compare it to the terrain in front of me.  Identification of features such as buttes, mountains, waterways and the relationship between feature and map are very important.  I make a point to visually reconcile what I see with the map.

I do it two ways.

First, correlate from topo map to the terrain.  Using the Cascade Mountain range as an example, from the trail head I should see the South Sister summit to the northwest.  Second, correlate from terrain to the map.  An example would be to observe Broken Top to the north east and then determine if that observation matches the map.

If this relationship cannot be made then I delay forward movement.  I want to be as dialed in as the compass.  This can be difficult in bad weather with limited visibility.  In such a situation I’ll check my GPS, verify and plot my position on the map.  I may resort to dead reckoning as I proceed.  To be certain, I plot my position more frequently.  Further, I’ll identify large terrain features that will become my “backcountry handrails.”  (Handrails can include roads, railroad beds, ridgelines, power transmission lines and streams.)   If possible, I’ll talk to others on the trail to learn of their observations and recent experience.

I always try to preload map software loaded into my GPS receiver. I can compare this information with that of my map.  First, I’ll set-up my receiver to report compass information in degrees true; matching my topo and compass.  Now I compare my GPS to my map and terrain.

Now that you have oriented your map, compass and GPS you have completed an important first step in land navigation and are ready to head out.

Ultra Light Backpacking Stoves

The following is a nice review by sectionhiker.com of the various types of stoves for the hiker.

Lightweight and ultralight backpackers have a lot of different options available when it comes to picking an ultralight backpacking and camping stove. Here are the pros and cons of using alcohol stoves, canister stoves, solid fuel stoves, wood stoves, and just going stoveless.

Alcohol Stoves

Alcohol stoves are popular with ultralight backpackers and thru-hikers because they burn denatured alcohol, which is inexpensive and widely available, particularly in small towns that don’t have an outdoor outfitter that  sells more specialized camping stove fuel. For cooking, alcohol stoves are best used for boiling water which is added to dehydrated freezer bag meals or Mountainhouse style camping meals, although some alcohol stoves are available with simmer rings that enable you to cook more complex meals. The downside of using an alcohol stove is that it is very sensitive to wind and must be used with a windscreen which can be awkward to pack. Alcohol fuel is also less efficient than most other types of fuel and it takes a relatively long tome to boil two cups of water (7-10 minutes).

My two cents:  Once lit and alcohol stove can not be safely moved - my opinion.

Solar Flares

Good article about the issues surrounding a solar flare.

By RICK MONTGOMERY

The Kansas City Star

When the sun got ornery in 1859, American telegraph operators saw sparks fly.

A huge solar flare belched a cloud of charged particles into Earth’s path. But other than frying telegraph lines, the electromagnetic collision caused little stir in the world.

Nobody back then had yet switched on a decent light bulb, much less charged an iPhone.

Yet the sun hasn’t changed its ways, and that worries University of Kansas physicist Adrian Melott, among others. If the remnants of a similar solar flare struck the planet today?

GPS Waypoints

Managing your waypoints isn't hard to do.  But one simple step gets you on your way!

I really like to keep my navigation simple.

Simplicity now makes life a lot easier when a potentially bad situation occurs or when someone in your party is injured. 

Before leaving home I "dump the junk" or get rid of those old, meaningless waypoints.  At the trail head I'll reset the "trip computer" and the track log (the bread crumb trail.)

On the trail I always verify that a waypoint has been saved.  Verification is a simple step that has saved my bacon more than once.

Waypoint List

When it's time to return to camp or home, there is nothing more unnerving to find that the waypoint you need isn't on your waypoint list.  In the illustration to the right, the waypoint to "home" isn't there.

It is easy to make this mistake.  Perhaps after executing the waypoint function you hit the OK button or you selected another option without saving "home" to file/memory.



My recommendation is to verify by selecting/depressing the "find" button (Garmin) and then selecting "waypoints" to view the waypoint list (figure above.)  If home appears you are ready to go.

Map Page 

Another quick way to verify is to go to the "map page."  First zoom in to about 800 feet or to a zoom setting where you can see waypoint names on the screen.

Verifying a waypoint will save you a lot of angst and worry later.

Wolves in Oregon

The following is an article from the Portland Oregonian about the wolf population in Oregon.  Do note the info wolf OR7.  This male has wondered through Oregon, visited California and crossed into Nevada. 

By Rob Davis

Hiking on Mount Hood? Keep your ears open for a wolf’s howl.

Wolf tracks were found in the snow on Mount Hood’s eastern slope in December, the first sign of the species’ presence in the Cascades since the famous male known as OR-7 left eastern Oregon and crossed the state in 2011. 

It's the first known Mount Hood visit for a wolf since their recovery from the brink of extinction began.

“This is history,” said Rob Klavins, wildlife advocate for Oregon Wild, an environmental group. “It shows that if we give them a chance, wolves can recover in Oregon. The potential is there to hear the howl of wolves at Timberline Lodge.”
