The accumulated snow brought down countless trees, limbs and power lines, at one point leaving nearly 200,000 utility customers without power. In areas of the state outside of certified local government jurisdictions, the design snow load shall be based on the ground snow loads developed in "Snow Loads for Structural Design in Montana", authored by F.F. As shown above, the ground snow loads in 2010-11 were significant, but did not exceed those prescribed in ASCE 7. This occurred during the year that ended December 31st, 1956. The mandated meetings are typically scheduled at the last meeting of each year. That is, drifting at the LCD sites in question occurred in January 2011, while the peak ground snow load as well as the onset of reported roof problems typically occurred in early to mid-February 2011. If you want to calculate these values by hand, use the following formulas: snow load = thickness density The result - snow load, or the pressure exerted by the snow - has the units of kN/m or lbs/ft. Ground source (geothermal) heat pump systems extract heat from the ground during cold weather via an underground pipe system.

Also, most snow happened almost perfectly from sunset to sunrise, meaning strong mid-April sun didn't have much effect. However, again due to differences between the mapped design values in ASCE 7 and individual site specific 50 year values, the 2010-2011 winter ground snow loads approached the mapped 50 year design values but did not exceed them.
