Concerns about potential cattle losses prompted Colorado to airlift hay to the hardest hit areas, including the use of UH-60 Blackhawk helicopters from the Colorado National Guard and a C-130 from the Wyoming National Guard. Losses in a similar storm in 1997 resulted in over 27,000 cattle fatalities with an economic loss of $27 million. Final losses were estimated between 10,000 and 15,000 cattle in Colorado. Overall, National Guard units, including ones from Wyoming and Oklahoma, dropped feed to an estimated 345,000 cattle stranded by ten foot drifts.
