Sixteen to eighteen inches of heavy snow was reported in the foothills southeast of Leadore. Visibility reduced to one half mile or less at Gilmore Summit on Highway 28 due to snow during the morning and afternoon hours on the 15th.

The wider storm

After a hot start to September, a cold weather system brought widespread low elevation rain and snow accumulations above 6000 feet across the Northern Rockies impacting back-country hunters, wildfire crews and travel across mountain passes. The large degree of change coupled with the somewhat unseasonable timing of this event produced greater than normal impacts.
