An MRT is required before operation, and I think every other year after by Z98 (Canadian code for passenger cableway) Visual inspections are done more regularly, but you canít spot broken wires easily, especially if theyíre internal where theyíre broken internally.

    My post was in response to an earlier post that had pictures of a lift being prepared for an ultrasound inspection. That surprised me, but I learned it is actually a thing.

    But the sun isn't out at 4am! How can that be explained?

    Maaaaaybe itís a black sun you canít see

    You mean stress, not fatigue. Areas with stress concentrations are prone to fatigue cracking, but fatigue and stress are not the same thing.

    I've that this same thought since I've been maybe 4 years old... what if the cable snaps? Is it being inspected regularly? What if rust gets in there during the summer? Better just trust it and go with the odds that it will snap with someone else onboard...

    I stand corrected. Which happens a lot

    To add to that an exploration in Fatigue cracking:

    The name “fatigue” is based on the concept that a material becomes “tired” and fails at a stress level below the nominal strength of the material. The facts that the original bulk design strengths are not exceeded and the only warning sign of an impending fracture is an often hard to see crack, makes fatigue damage especially dangerous.
    ...
    In order for fatigue cracks to initiate, three basic factors are necessary. First, the loading pattern must contain minimum and maximum peak values with large enough variation or fluctuation. The peak values may be in tension or compression and may change over time but the reverse loading cycle must be sufficiently great for fatigue crack initiation. Secondly, the peak stress levels must be of sufficiently high value. If the peak stresses are too low, no crack initiation will occur. Thirdly, the material must experience a sufficiently large number of cycles of the applied stress. The number of cycles required to initiate and grow a crack is largely dependant on the first to factors.

    In addition to these three basic factors, there are a host of other variables, such as stress concentration, corrosion, temperature, overload, metallurgical structure, and residual stresses which can affect the propensity for fatigue. ...

    7) The Perseids meteor shower.*

    One of the brighter meteor showers of the year (provides midnight sun almost) and tends to peak around August 9-13.

    8) Lightening - June 20, 2019. Appears to be on the side of the Squamish Chief or it could be further back, maybe along the gondola line???*

    Fair enough that ultrasound can work on cable, but the Canadian code z98 specifically requires MRTClick image for larger version.

    Iím assuming the ski the east group is in the US. Plus I also donít trust most people who post info on social media about ski lift stuff, most of them donít have much clue what theyíre talking about.

    I didn't know this until today ... but the actual name 'Squamish' means:

    "Mother of the Wind"

    A squamish is a strong and often violent wind occurring in many of the fjords, inlets and valleys of British Columbia. Squamishes occur in those fjords oriented in a northeast-southwest or east-west direction where cold polar air can be funneled westward, the opposite of how the wind generally flows on the Coast.
    ..
    The town of Squamish, British Columbia, is named for the wind, and upper Howe Sound, just off the Squamish River estuary, is known widely in the sailboarding world for its excellent, steady winds.
    Now I find that very interesting, especially looking at the accounts of a Squamish meteorologist, and the range of the original Feb 4, 2014 incident, as well as recently. From the Jan Feb 2014 range:

    https://twitter.com/search?q=(from%3...rc=typed_query

    And recently, freak thunderstorms:

    https://twitter.com/Squamishweather/...79554726658049



    Now, according to 'Observation 3' on page 17 of the 2014 incident report:

    The site selection process as it is outlined in the Z98 standard requires that “consideration shall be given to factors that are known to affect the operational requirements of the installation, such as wind.
    ...
    It is incumbent on the designer to make this evaluation of the site and to gather data from appropriate sources to determine where along the line wind monitoring devices must be located.
    ... Where that experience does not exist, data may need to be gathered from other sources, such as wind studies, in order to determine appropriate locations for wind monitoring.
    ...
    These studies may incorporate wind modeling methodologies to better understand the effects of wind along a proposed alignment. This is similar to the practice that exists to evaluate passenger ropeways located in avalanche terrain by collecting data through snow studies to establish snow safety plans for safe operations.
    I've added '...' just to break it up into bite sized sentences.

    The Sun has a well-documented history of funding and supporting third-party militant organizations when it is unable to maneuver against its opposition directly and overtly, or when it benefits from maintaining an appearance of inculpability.

    In this case, I would rely on high-confidence intelligence reports that describe a long-standing relationship of The Sun providing resources to The Moon in exchange for sustained operations during the nighttime hours (including the 0400 hours time of incursion).

    Additionally, The Sun has previously been witnessed to enlist the aid of more distant, but no less sympathetic, stars in its campaign of destabilization and chaos. Similar to The Moon, these outside antagonists routinely perform wetwork under the cover of nightfall, and may possibly share responsibility for the attack in question.
