    Photo assignment: Trail and land destruction in NorCal.

    We're experiencing a land shaping event with these storms. With little warning, these storms rival the strongest systems of the last 25 years, or even 100 years in spots.

    This will reshape our land and the way we think about infrastructure and policy. It'll cost a lot of money as materials and labor demand will be insatiable.

    So, get out there and share some photos and links.

    Oh the horror

    OK so this is a little slide on a little trail but there's a bigger lesson here:

    Photo assignment: Trail and land destruction in NorCal.-16601561_1724307667883493_4181170929720609955_o.jpg

    This is on the new-as-yet-unopened E-Conn (JDT) trail in Coe; we've got a few of these little slides to clean up and all of them are in areas we "cheated" and didn't cut the back-slope to "spec" (slope of 1-to-1 for regular soil, can be steeper if mostly rock).

    Drive around on any older back-road in the Bay Area and what kind of back-slope do you see? Usually much steeper than 1-to-1 (aka 45 deg or 100%); those road builders cheated there too. Much easier/cheaper to cut the bare minimum and cross fingers. ("If it fails THEN we'll do a retaining wall") If the natural slope of the hill is 45 deg or steeper a road prolly shouldn't be built there in the first place.

    With enough roots in the soil sometimes these over-steep cuts last for decades; with the recent drought roots aren't doing so well. WYSIWYG.

    A river "of mud" runs through it.

    Photo assignment: Trail and land destruction in NorCal.-dirttunnel_img_6082.jpg

    Ran into this on my ride today. About a foot thick and the consistency of wet cement. Continues from here for 40 yards down the trail.

    Didn't have a camera but the section of trail across the slide in Stevens Cyn. between the end of the road and the map sign is washed out. Only the steep drop to the left side is left with a big muddy rut at the bottom.

    Hwy 152 near hecker pass. We chatted with a CHP who says there are no quick plans to fix it - they are waiting for it to 'dry out' first. Nice biking on a highway with no traffic!

    Didn't get a pic on Sunday, but Skyline between the new parking lot and Bear Creek Rd by Skeggs looks mighty sketchy. That was the section of road they had down to one lane last year, and a big chunk of the hill below slid down in the last couple of weeks. The road is fine, but there isn't much room for any more to slide.

    Went for a road ride on Sun in Santa Cruz with some friends. Ran into this on Hwy 9. It was dried out enough that we could hike over it, but it sure was a mess.

    From the tracks in the mud it looked like one intrepid MTB'er had gone through it..

    There were a bunch of smaller slides up their too as well as road subsidence. Not going to be pretty after the coming storms.

    In case I wasn't clear, the slide is on On Orbit. Bohlman is still open.

    Now is a good time to get some photos of erosion happening on hiking-only trails.

    MTBers are labelled as erosion boogie men, but the impact we have over 25 or even 100 years pales in comparison to the damage that rain runoff can cause in the course of a few days or even hours on poorly built or poorly located trails, regardless of who is using them.

    This is the message MTB advocacy groups have been giving for decades: how the trail is built has a greater environmental impact than who uses it. Now you have the proof. Go forth and document it.

    In SoCal a lot of the battle is against the equestrian community because horses destroy trails worse than mountain bikers. Because of that I always come to a complete stop and wait on the side of the trail for horses to pass. I've seen some horses go crazy, but also they will have nothing but good things to say about my behavior, and no Strava segment is important enough to lose cycling priveleges.

    FC,

    Last week we finally got to see the damage, up close and personal, to the infamous Widow Maker Trail here on the Mendocino Coast. The first picture shows where the trail use to go into a series of switch back turns. Now, it is impossible to even figure out where the trail is on the other side of this 100' wide landslide. The length of it is at least 300 yards where 100's of cubic yards of mud and debris slipped into the upper sections of Hare Creek drainage.

    Photo assignment: Trail and land destruction in NorCal.-img_0314.jpg

    This is just the upper section of the slide which is about 40% of total slide.

    Photo assignment: Trail and land destruction in NorCal.-img_0320.jpg

    Widow Maker may not open up again this year as the soil in the slide area is very unstable at the moment. Near the top are several tall Bull pines teetering on exposed root balls.

    Work on re-establishing trail route could possibly begin in late May or early June, once things dry out, if ever.

    Yea, that area got washed out and was rerouted in 94/95 as well. I was up there 4 or 5 weeks ago, and it was still ride-able, but the creek crossing had been washed out on the uphill side.

    I went up the canyon today (2/19/17), the slide area is wet but rideable. The right side (main trail) is washed out, but the left bypass is still okay. The trail is washed out at the creek, but you can get through and there are some very large rocks (2' to 3' dia) on the trial close to the Indian Creek Trail intersection.

    Upper enchanted loop (on the old road where you go under that rock outcrop) had a pretty big fill failure. Was stoked to be back in SC for a bit and help out with the fix. From MBOSC instagram.

    since I shot this the water has come up over the bridge. Livermore is cut in two. The creek overflowed the roads at Concannon and S Livermore, Arroyord between Concannon and 4th st, and the bridge at Holmes and Murietta

    It appears, concerning our crumbling California State infrastructure, the gubernor is in a similar state:

    Past the green steel bridge by maybe 1/3 mile and within the "closed" GYHS area. No impact to regular park use but messes with GYHS special events. They think they'll be able to fix sooner than later.

    For whatever reason they do have GHS Rd closed at HH parking just before the HH Creek bridge. Also GHS Rd has been closed almost daily past Coyote Lake making Canada Rd the only reliable way to get to HH.

    Same reason we'll spend thousands on unnecessary component upgrades, yet wear brake pads down to the backing plate and scrap a ride.
