NOTE: The area near the Mueller tunnel remains closed as this entire section was destroyed by an avalanche of rocks. Even in March, 2009, rocks were starting to slip down onto the Mt. Lowe Fire Road just below Eaton Saddle. This basically means that this ride route is not accessible via Eaton Saddle.
You’ll find a more recent photo of the destruction in a post by Altadena Online Jan 27, 2011.
