It has always been confusing to know which shelter to reserve. Some shelters are more remote than others, and some are built close, making it ideal for larger groups. For quite some time I had been hoping to map out each shelter area and make that info available on this site. However, Chris Small from Hiker101.com beat me to it!
Chris evidently used way points to mark each shelter at all the shelter areas. Then, using satellite maps, he was able to locate and show where they are situated. He also added the location of some tent sites and privies. Chris gave me permission to publish them on my site.
In addition to the satellite photos, you can also find the Park’s official map of each area.
