12/19/09 - Mt. Wilson Trail Closed Due to Rock Slide (received from City 12/17/09)

MT. WILSON TRAIL CLOSURE – due to a large rock slide, Mt. Wilson Trail will be closed until further notice. The heavy rains have caused a large amount of large rocks & debris to block the trail making it very unstable and unsafe for hikers. The damage will take some time to clear and at this time it is unknown when the trail will re-open. Residents and visitors are not permitted on the trail. We are sorry for any inconvenience this may cause and thank you for your cooperation. Violators will be cited SMMC 9.24.090.

For updated information, please look on the City’s website www.cityofsierramadre.com or contact the Community & Personnel Services Department at (626) 355-5278.

12/12/09 - Personal Observations posted 10:30pm

The following observations were posted real time via mobile phone on my blog, http://sierramadrenewsnet.blogspot.comAs much as possible, I'll be posting to the blog real time as I'm driving around, then re-posting here.  If there's something in parentheses, that's been added as I'm posting here.  The photo of  Skyland is being posted for the first time now.  In the future, I'll be posting photos from the field, but only during the day.  My iPhone just doesn't have the capability to take night pictures.

9:10pm - Auburn debris basin looks good. LACDPW truck driving up as I left.

9:18pm - 1 Carter and 1 Carter east all clear. Truck pulling out from behind closed gates at top of Baldwin as I went by so somebody is monitoring it.

9:25pm - Skyland is closed due to mud. (North end at, if I remember correctly, 875 Skyland, not sure where the south end closes, click photo to enlarge).

9:33pm - Mud on Skyland pretty much stops at Idlehour.

9:41pm - Woodland, Alta Vista and Yucca Trail all clear.  LACDPW truck coming down Woodland as I we(n)t up.

9:52pm - Camillo, Lotus and Sunrise Hill all clear. LACDPW coming down as I went up again. They're all over. (probably the same truck at most if not all these locations).

10:06pm - Went up Stonehouse by search and rescue. Dead end looks like potential for mud but the street is clear as of now. LACDPW is here too.
