I marked up the next picture with the arrow indicating the area of the block that detached and slid as down into the lower Racehorse Creek canyon in 2009. The headwall area of the older and much larger slide that spilled out across the Nooksack River valley is marked with a dashed line. Note that additional logging has taken place between 2015 and 2018 along the southwest side (right in the picture) of slide.
Logging had taken place on and adjacent to the 2009 slide shortly before the failure took place. As can be seen in the photograph above additional logging has been taking place along the older large slide headscarp and along a block that has remained attached on to the right of the slide. That block is located on the south side of the slide.

The impacts of logging on large deep-seated landslides is uncertain. It certainly is not positive, but a direct connection between logging and reactivation of deep-seated bedrock landslides has not been firmly established. The 2009 slide was certainly coincidental with the logging that had taken place, but it also took place during a very intense rain on snow event that was likely on the order of a 25 to 50 year event. Estimating the water input difference between the slope harvested and not harvested might be an informative exercise. I am not aware if anyone has tried this. The land in question is managed by the State DNR.
Various parties had press releases. Bob Ferguson has perplexed some with his position and taking this case to the Supreme Court in direct conflict with the position of the governor and the Washington State Lands Commissioner of Public Lands. I add a bit of commentary at the end and will do a future post with a bit more. In any event, the lower court ruling standing is a big deal.
Washington State Attorney General Bob Ferguson issued the
ruling brings a resolution to a case that has gone on for nearly 20 years,
defended by multiple attorneys general. It is unfortunate that Washington state
taxpayers will be shouldering all the responsibility for the federal
government’s faulty culvert design. The Legislature has a big responsibility in
front of it to ensure the state meets its obligation under the court’s ruling.
It’s also time for others to step up in order to make this a positive,
meaningful ruling for salmon. Salmon cannot reach many state culverts because
they are blocked by culverts owned by others. For example, King County alone
owns several thousand more culverts than are contained in the entire state
highway system. The federal government owns even more than that in Washington
state. These culverts will continue to block salmon from reaching the state’s
culverts, regardless of the condition of the state’s culverts, unless those
owners begin the work the state started in 1990 to replace barriers to
forward to working with tribal governments to advocate for the funding
necessary to comply with this court order, and to ensure other culvert owners
do their part to remove barriers to salmon passage."
The cost impacts are relatively modest in the scheme of the entire state transportation budget. At issue was the State's obligation. That is not the same as the Federal government; Mr. Ferguson knows that, but wants to complain about the different treatment. Some have expressed concern that counties and cities may have to follow a similar path; however, that was not before the court and Mr. Ferguson is over simplifying the problem with other blocking culverts - the lower court already determined that issue and the State's position was vague.
commissioner of public lands, issued this statement:
decision affirms that it is our collective responsibility to ensure the
survival of Pacific salmon. This decision is fair under the letter of the law,
but it is also just. Protecting salmon is an issue not just of importance to
Washington’s tribes, but to all of us.
The time is
now to think boldly about how we move forward on many fronts, including
the Department of Natural Resources, stands ready to work with tribes, state
agencies, counties, private landowners and federal partners to restore and
protect our treasured salmon.
It is time
to stop fighting over who should do what. Instead, let us roll up our sleeves,
stand shoulder to shoulder, and get to work saving our Pacific salmon for
future generations. It’s time to do the right thing."
Based on previous statements by Ms. Franz, she gets that this issue is bigger than just the tribal fishing rights - expanding fish populations will benefit both tribal and non tribal fishers.
Palms in gardens in the Pacific northwest are always a bit of a surprise. They just seem so out of place. This stand of palms is on the coast of Key Peninsula, part of the complex of inlets that make up of the southern end of the Salish Sea/Puget Sound.
A few weeks ago we had a stretch of weather where the rain came not out of the west but from a low pressure system in Oregon which wrapped the atmospheric flow around to flow into western Washington from the southeast. The result in northwest Washington was some turbulent clouds coming over the North Cascades.
The result was a brief moment of remarkable lighting. The western sun lighting the twin dogs with the Twin Sisters rising above a low cloud bank.

Health and safety meetings and plans are part of a lot of work places. The idea is to reduce the unexpected - that is anticipate the things that can cause a safety issue. The picture below shows a safety issue that has caught me and recently gave an associate a problem.
The cobble beach makes for tricky footing as the cobbles shift while walking and can also be slippery. Hence, one gets preoccupied with watching carefully where to place a step. Hence, it can be easy to loose site of a large sharp log sticking at out at 5 feet 8 inches above the ground.
It is sort of a funny thing to receive a hard joust from a stationary spear or log. Its even funny when it happens to you, but it sure can hurt while at the same time making one feel very silly.
I see Lontra canadenis (river otter) on my coastal ventures. On rarer occasions I will see Neovison vision (American mink). We spotted this mink passing below us on the beach on the north shore of Orcas Island. I was struck by its comfort of being so much out in the open.
The same day and not very far away we heard screeching that I initially assumed was a hawk. Instead it was two minks rolling down the bluff slope and biting at each other.
My take was that this was not a fight but was mating - but I am no expert on the ways of mink courtship or dueling and found the encounter confusing. I will say that the minks in question seemed rather oblivious to my presence with their full attention on each other.
