I believe it was the Bridger Bowl Ski Resort in the Bridger Mountains, which recorded 72 inches in 24 hours. I skied it, and we were told that it was a record. I found this "site", if you can call it that http://www.avalanche.org/~issw2004/issw_previous/2004/proceedings/pdffiles/papers/046.pdf It isn't much, but it does concur. Note: the record was a world record, not a U.S. record. The exact number of 72 inches I only know because I was there. On our first ride up the lift, at the top, a ski-patrol, who had just received notice of the measurement, shouted to the people riding up the lift that it was 72 inches. 6 feet exactly.

The duration of Twenty Hours is 1.83 hours.
To find the rate of snowfall in inches per hour, divide the total amount of snowfall (29 inches) by the number of hours it fell (8 hours). Rate of snowfall = 29 inches / 8 hours = 3.625 inches per hour. Therefore, the rate of snowfall during the storm was 3.625 inches per hour.
