[pct-l] Snow pack in California

[Denis Stanton]

Can anybody give me an approximate definition  of the terms North, Central and South as used on the Snow Water Content graphs at http://cdec.water.ca.gov/cgi-progs/products/PLOT_SWC.2010.pdf    ?

I'm about to embark on the forth segment of my long-term section hike of the PCT.  I started from Kennedy Meadows in 2007 and have made it to Woods Creek so far, but I don't know if that is Central or North on this web page

regards
