      Hardrockers,

      Below is the Silverton UNOFFICIAL snow report for the 2010 season as of May
      1st. The snowfall continues to be close to average with most San Juan
      Mountain SNOTEL gauges showing below the 30 year average for snow water
      content. The last few weeks have seen significant snow melt according to the
      SNOTEL gauges.

      The SNOTEL web site provides a lot of snow water content and other data for
      Colorado and other western states.

      I visited Silverton on Sunday, May 8th and there is a lot of snow up high.
      I dorve up to the Cunningham Aid Station. The Cunningham road had been
      plowed but, at several places, melting snowbanks almost blocked the road.
      The day was gray with snow flurries but the ground was not frozen. Water
      was roaring off the Dives waterfalls. I got a good look up Little Giant and
      all was white above tree line. I'm looking forward to getting up there for
      the run.
