Sullivan Canyon Closure Update

Tuesday, June 8th, 2010

From Sharon O’Rourke of The Gas Company

As of Friday, June 4th, we completed the initial access road repair work.  Access from Mulholland was re-opened to the public as of Saturday, June 5th.

On Wednesday, June 23rd, we will start the pipeline protection work which will include the final planned access road repairs and covering the remaining pipeline exposure areas with the concrete mats.  This will require closing public access to Sullivan Canyon at both Mulholland and Queensferry Road.  The closure is necessary for public safety due to the equipment needed for the placement of the mats.   The work is estimated to take 3-4 months.

Update August 31: Apparently the canyon will be closed until November 12th.

Las Virgenes “Tar Pits” are a Natural Phenomenon

Friday, June 4th, 2010

Just three days ago a local rider contacted CORBA about an oily sheen seen in some of the still water sections and mud holes along Las Virgenes Canyon. This appeared to be a new phenomena, and the thick, dark mud and oily sheen look suspiciously like petroleum or oil products to the untrained eye. While there are oil pipes in the area, they don’t pass under the creek at this particular area, and it is somewhat alarming to come across.

Nobody at CORBA was familiar with this problem, so we alerted the MRCA. Chief MRCA Ranger Walt Young toured the area and took water samples at the three water crossings. He reported that the petroleum like sheen was present, but there was no smell of petroleum, which is common in other areas where natural seepage occurs. There was also plenty of life in the stream in the form of tadpoles and plant life.

A sample of the dark muck which has the appearance of tarry oil, dries to a fine brown powder with no evidence of the presence of oil.

The local Pipeline operator was also brought in for an assessment. Their pipes are pressurized to 500 PSI, and they noted that any leakage at that pressure would be immediately evident. There was no evidence of any leakage. Also, the dark oily-looking muck would float if it were oil-based, and there would be a strong odor of oil.

The final conclusion is that whatever seepage is there is a natural phenomenon, and is not a cause for concern. It may be the result of an above average rainfall year, or recent earthquake activity, but is not from a man-made source.

There are places in Southern California (Tar Creek in the Sespe Wilderness comes to mind) where large amounts of oil and tar do seep to the surface naturally and globs can be found floating down the stream. This reported seepage along Las Virgenes Canyon is much more subtle.

If anybody riding or hiking any trail sees anything suspicious or out of the ordinary, it is always best to contact the local land manager, law enforcement, rangers or of course you can always contact CORBA and we will notify the land manager. Thanks to rider Gary Artis for bringing this to our attention so that we could have it investigated further.

More Unauthorized Trails “Closed”

Thursday, June 3rd, 2010

By Mark Langton

More trails, this time in Point Mugu State Park, have been deemed unauthorized and marked with signs and fencing designating them as closed (View our earlier article on Malibu Creek State Park). One trail, known as “Art’s Trail,” connects Sage Trail and Sin Nombre, paralleling the paved road that leads to Wood Canyon. Two other shorter trails connect to the paved road farther to the west. Here is the narrative and explanation given for these actions from  Dennis Dolinar, District Maintenance Chief, Angeles District, California State Parks:

Last weekend, I participated in a project with a group of local boy scouts from Newbury Park to erect a combination of both fences and barriers on the four entry points to a set of unauthorized trails that lie in the backcountry of Point Mugu SP. I had become aware of these specific trails a couple of months ago while working with others on a new official trail map for the park. After discussions with our both our Senior Environmental Scientist, Suzanne Goode, and our District Archeologist, Barbara Tejada, I decided to take the steps necessary to close this set of trails until such time as they can be fully evaluated in terms of both user safety and possible resource damage.

The trails in question are totally unofficial and, as such, they probably go by various names in the hiking, biking and equestrian communities. A private website known as Ventura County Trails uses the following names to describe the trails in question. The main segment that travels roughly parallel to Ranch Center Road from Sin Nombre Trail to Sage Trail is been labeled by them as being “Art’s Trail”. In addition, there’s two short connector trails that go up to the paved road that have been given the names “Kubler” and “Clark”. It appears quite possible to me that these routes started out as little more than game trails that skirted the large, fragile meadow but, with repeated use by those park visitors who somehow knew that they existed ( they do not appear on any official state park maps ), they have become more obvious over time. Attached you will find a location map of the closed trails.

At this point in time, the trail entrances have been closed by use of simple barriers and fences but there are no immediate plans to destroy the trails themselves. The hope is that we can stop and/or minimize the use of this set of trails until such time as staff can evaluate the park resources that are potentially effected by these types of visitor use. Many of the people I spoke with out on the trail last weekend were disappointed but seemed to understand the need for us to manage this issue.

As time and work priorities allow, I will get back to you and your organization again as to our progress on this ongoing project.

While the above explanation is not wholly acceptable, it is within their purview to undertake these actions. What is most frustrating about the above comments is that State Parks is expending resources on projects that lack more comprehensive internal, peer, and constituent review and input. CORBA is monitoring this situation closely and will have more information as we obtain it.

Angeles National Forest Recovery Plans

Tuesday, June 1st, 2010

There was an informational meeting on the recovery plans for the Angeles National Forest May 26, 2010 at the Eaton Canyon Nature Center.  Representatives from the U.S. Forest Service, San Gabriel Mountains Trailbuilders, the Sierra Club, TreePeople, Student Conservation Association, Caltrans, and Outward Bound were present.

The intent of the Recovery Plan is to create a more ecologically sustainable forest than before and to build a community of involved users.

There was a brief mention of San Gabriel Mountains Forever, a group the Sierra Club supports and that has the goals of promoting the proposed San Gabriel National Recreation Area and of increasing wilderness in the San Gabriels.  CORBA is investigating this wilderness proposal and its potential impact on multi-use trails.

An intern from Congressman Schiff’s office announced an upcoming informational meeting on the Rim of the Valley Corridor Special Resource Study.  The Corridor is a Santa Monica Mountains Conservancy project to expand the National Recreation Area. The meeting will be at the Nature Center at 10 am, Friday, June 4.

Mike MacIntyre, the River District Ranger for the Angeles National Forest discussed the new closure order.  Details of that are on the ANF web site.  He showed some photos of the extensive damage to the upper Arroyo Seco, Gould Mesa Road, several fire stations, Grizzly Flats Road, and Vogel Flats area.  He reported that a large boulder had been blasted from the Mt. Wilson Toll  Road near Mt. Harvard. He also confirmed that Millard campground is open, but not El Prieto, Sunset Ridge or other trails.  They are looking to open more areas by the July 4th weekend.

He noted about 35,000 acres of forested land burned, 24,000 of that was pretty much denuded and may not come back on its own.  There are plans to reforest about 11,000 acres of the 24,000.  Seedlings were not available to get started this year, and planting is expected to start with an initial 4400 acres in early 2011.  Carbon credits, grants, and Congressional sources will fund the project.<

A representative from the Tree People explained that there is a narrow window for replanting because the soil has to warm and be moist. If they wait too long it is too hot and dry for the seedlings to survive without watering, which is usually not practical.  They are recruiting and training for 2011 now.  Tree People are the lead group on the reforestation efforts.

Bob Cates reported that the Sierra Club’s Angeles Forest Restoration Project will be working on trails the 2nd and 4th Saturday of every month starting in July. They have 380 volunteers signed up. They focus on the area up Highway 39 to Crystal Lake.

The Student Conservation Association is 50+ years old, but until 2004 did not have a presence in SoCal.  They have both paid workers and non-paid volunteers. Besides doing all kinds of conservation related work, they encourage participants to consider careers in forestry, wildlife management, conservation, etc.  They have some crews working with the USFS on the fire recovery.  These crews work for several weeks at a time, so can get into back country and handle more complex jobs.

The final speaker was Patrick Chandler from Caltrans District 7.  There were 25 washouts or slides along the closed section of Highway 2.  Caltrans are hoping to have it open by mid-July.  Most of the problem was that the debris flows blocked all the drains, then the water washed across the road and off the down side eroding the shoulders and below and undermining the roadbeds. Although the engineers wanted to, they are not going to build any bridges, as there are no funds available.

Thanks to CORBA member Mitch Marich for the report.

New Millennium Trail Maintenance Report.

Tuesday, June 1st, 2010

Clearing out the weeds that choked the trailOn Saturday 5/29/2010 a dozen CORBA volunteers and a hand full of men from the MRCA fire crew spent the day cutting back brush and doing some tread work.  We worked the Calabasas Crest Trail starting just South of Calabasas Road up to the water tank at the top of the switchbacks.  We had a hard working crew and managed to clear weeds and do tread work on 1.5 miles of trail!  There was a lot of thistle along the trail so it was not an easy task! you can view our work in the photo gallery.

The following day we returned to ride the entire trail to survey the conditions of the remainder of the loop.  The MRCA fire crew has maintained much of the North end of the trail and it is now clear of brush.  The South and West sides from Normans Way to the Bark Park Trail is in need of some brush work but it is passable for those not minding a little bushwhacking.  Keep in mind there is some thistle in there so long pants or knee/shin guards would be a good idea.

CORBA will be checking in with the Land Managers to coordinate getting the remainder of the trail maintained.
