The PCT google map fire perimeter overlays have been updated to give you a stark view of what has burned. Go to the PCT Map and from the 'Map Skins' list box, scroll down to the fire section and select the 2001-2014 or the 2009-2014 fire overlay.
From 2001 - 2014, the southern most 500 miles of the PCT has seen 49% of the trail burned. That's 246 miles folks. From 2009 - 2014, 20% of that first 500 miles has burned.
Hey, PCT hiker, this is where you come in. As California undergoes the first mandatory water restrictions is history, you should be thinking about fire safety. Leave that alcohol stove at home. No, you don't need that camp fire.
There's also a set of overlays for the CDT, too.
Be very careful out there!
