Rawlins, Wy – Blame Mother Nature and not an experimental cloud-seeding effort for the heavy snow that fell on the Snowy
Range and Sierra Madre Mountains this winter.
Bruce Boe of Weather Modification Incorporated thinks the
experimental cloud-seeding effort that got into full swing this
past winter may have added a small amount of snow to the
above-average snowpack in the mountains.
Weather Modification of North Dakota is carrying out a carefully
controlled five-year study of cloud seeding using the Snowies,
Sierra Madres and Wind River Range.
The study is funded by the Wyoming Water Development Commission
and data is being evaluated by the National Centers for Atmospheric
It was commissioned a few years ago in order to prove or
disprove the theory that cloud seeding can increase snowfall.
