Check out their webcam! Haven't seen them make snow this early before.

    Lots of places are making snow well before an assumed opening date. Bolton Valley started blowing last night and doesn't plan to open until Dec. 9. Given MRG is based almost entirely on natural snow, so who knows when actual skiing can start there.

    Yep, started on Nov. 8. Never seen so early, and never on the single first. Seems like getting practice slope covered first makes more sense in order to have a lift run without natural snow, but lower single gets a lot of traffic and scrapes off fast, so might as well roll the dice.

    Bolton takes a long time between starting snowmaking and opening because they have very little pumping capacity.

    They did quite a bit of work to up their game this year: 
    "Bolton Valley is upgrading its snowmaking system prior to the 2017-18 winter season. The pumps at the Timberline pumphouse will be balanced, allowing for more water to be pushed uphill more quickly. The resort is also expanding its gun and hose inventory. Combined, these two upgrades will allow the resort to blow snow in multiple locations at the same time. The additional guns and hoses will also reduce downtime when the crews need to change locations. The overall benefit will be more snow earlier in the season and more trails getting covered faster than last year."

    We're drifting off topic, but what is even "rebalancing" a pump? Like how you balance a tire so it won't wobble?

    "Upping their game" would be when they can pump more than 1500 gpm.  Fact is Bolton has the least powerful snowmaking system by acre in New England and they usually get a pass because of their significant snowfall.

    Yes exactly, and it's more than that.  To continue the car analogy -- It would be like balancing or re-machining the axle and sometimes machining the rim, and repacking the seals and maybe new bearings.

     But just like a tire the main point is eliminating vibration (which can be caused by multiple factors) to improve performance and prevent premature failure.  Shaking tire going whop whop whop on the highway will soon damage other components, same with pump but pump is even more critical.

     Pump in a piping system is just like that pump in your body, It's the key to the whole thing.   

    Unbalanced pump leads to bearing wear, seal failure,

    Usually it means balancing the rotor and or impellers or any rotating part. Depending on the size of the pump it can be major surgery
     


    rolling equipment, milling equipment, even large fans need to be balanced and there are service companies that specialize in this.  

    I'm not an engineer so I'm dumbing this down to my own limited understanding.  I do a lot of writing related to piping systems.
