        on lawns in the residential areas on the morning of the

        received 8 inches of snow.  Winds strengthened on the
        plains and produced blizzard conditions...reducing surface
        visibilities to less than 1/4 mile.  I-70 was closed
        from just east of Denver at Gun Club Road to the Kansas
        border.  Ten inches of snow fell at Strasburg east of

        45 mph with gusts as high as 60 mph produced 2 to 4 foot

        on Stapleton Airport.  This was the single heaviest
        October snowfall in 13 years since 1942.  The storm

        year.  Many trees that had not shed their leaves became
        heavily laden by the wet snow.  Many branches were broken...
        and a few trees toppled under the weight of the snow.  The
        landscape became one of rare beauty.
