BB — Bear box or bear locker (mostly in the Sierra)
CG — Campground

JMT — John Muir Trail
Hwy — Highway crossing
NF — National Forest boundary

Ski — Ski lift

WA — Possible water source (not on http://www.pctwater.com, mostly north of mile 700)
WR — Possible water source listed in the PCT Water Report at http://www.pctwater.com
WACS — Possible water source and campsite
