A break in the weather Saturday allowed search teams to resume the hunt for an avid Bend mountain climber who fell, possibly hundreds of feet, while descending the Middle Sister late Wednesday night.
This blog is about teaching, instructing and sharing practical applications to navigation, GPS technology and survival in the backcountry.

What Map Datum Do I Use?
What is the best Map Datum to use with your GPS receiver?
I was questioned about this recently in a GPS class. What is the best datum?
It just depends on what the hiker is going to do. If one is going to plot coordinates on a map then the datum (in the USA) to use is NAD27 CONUS (Continental United Sates.) This matches the map best.
Receivers come from the factory set to WGS 84. WGS 84 isn't the best datum to use with older maps. That said, mapping software (Terrain Navigator PRO) and www.caltopo can shift to WGS 84. Day hikers can feel comfortable using WGS 84 anytime. Cell phones use WGS 84 too.

The Hiker's Trip Plan
Leave a Trip Plan with a responsible person when you head out. Consider this to be the hiker's flight plan. As a minimum The Trip Plan is your backcountry itinerary.
I started my version of the of the Hiker's Trip plan back in 2006 after James Kim and his family became lost in step terrain of the Oregon coastal range.
I have learned that when people fail to return from a trip those calling for Search and Rescue (SAR) assistance generally have little knowledge of the details of the hiking party's plan. The Trip Plan gives the searchers more information. The Trip Plan provides the specifics. The Trip plan provides the details to begin an effective search.
To use the plan down load the document here. Write in as much information as possible. Attach a topo or Forest Service map of the planned route and identify the area to be traveled.
Do make sure your responsible person knows what you expect from them. Importantly as soon as the hiking party fails to return or check in - 911 is called.

The Best Compass
Frequently people will ask what is the best compass a hiker can buy? It really does make a difference.
My answer is that first I'll eliminate all the small ball and wrist watch compasses. Those models just cannot provide accurate azimuth/bearing information. They will provide a trend of direction but that is about it.
I'll then eliminate the inexpensive base plate models that can't be adjusted for declination. The small Silva models come to mind here. Some maybe suitable as a backup compass.
I find that the Silva "Ranger" style is my pick. It is accurate and keeps my navigation simple. Importantly, this model can be adjusted mechanically for declination, has a decent sighting system and is simple to use. Prices for this model will range from about $38 - $50. Suunto makes a similar model too that is just fine.
Unique to this style of compass is the sighting system. It's similar to sighting a hunting rifle. The compass box offers two methods (the notch on top and one at the hinge.) Read the manual about using the mirror's line that is scribed/etched into the surface.
Adjusting for declination keeps things simple. Just preset the declination value with the set screw (provided) for the area the hiker will be operating in. This eliminates the need to remember the rhymes associated with declination (East is least &west is best.)
