Laura asked if the smoke she was seeing in Carson City, NV is from the Big Meadow fire in Yosemite. Carson City is east of Lake Tahoe and south of Reno.
Yes, according to the map below. The smoke from the Big Meadow fire is going straight north to Lake Tahoe, Carson City, and Reno.
It looks like the folks in northern Idaho, Missoula, British Columbia, and Alberta have some air quality issues as well.
