You probably know Steve Messer, or at least seen him on the trails. His latest book in seriesWhere to Bike Los Angeles MTB was released this past December.
It's "a proper guide to our MTB trails. It is for mountain bikers specifically, and it is unforgiving in almost every detail about the best MTB rides our area offers... stats, elevations, directions, GPS points and even nearby institutions for after-ride nourishment."
Mt. Lowe's trails (and Shuttle Run too!) are featured. So now you'll never have to ask "what's the best way down?"
Find and get it from the website wheretobikeguides.com or at your local bike store.
