By far the best source of information on hiking in Southern California is Modern Hiker.

For a 6hr scramble, they’ve posted detailed trail information, fantastic photos, video clips, highlights, specific warnings, links to other trip reports, GPS coordinates with a link to Google Earth, …
And graphics like this:

Wow.
It’s far more detailed than any hiking guidebook.

I’ve been reading MH for months and it’s by far my favorite hiking blog. I don’t know how the team over there can do it all, but they do, every time out.
