    Lu,
    Is GPS navigation really available everywhere?
    In particular in the Polar regions?
    If not, what is the other reliable way of navigation in polar regions?
    
    Alex.

    Remember that this started as a discussion of why one would use celestial in 
    2015.   Emergency navigation was given as one possibility.   I rather suspect 
    that in the two examples given by Greg the explorer was using celestial as a 
    primary means.   That begs the question of "why?"

    Alex,Sam Willis used celestial navigation on his trip down the Grand Canyon 
    last summer. See link to BBC show that has Sam making observations using an 
    artificial horizon.http://www.dailymotion.com/video/x2f1pxgGeoffrey Kolbe 
    posted several years back on his North African desert celestial navigation 
    using a bubble octant. http://geoffrey-kolbe.com/C-Nav/index.htmGreg

     Greg,

    > A plastic sextant such as the Davis MK 3 wouldn't add much weight to the pack.
    
    You would add this to the the question or this is a part of an answer?
    
    Do you know any people traveling in remote wilderness (on land) who are
    using Cel nav, or carry sextants, almanacs, etc.?
    
    I have never heard of such people in modern times.
    
    Alex.
