Route for Southwest flights, Reno to San Jose?

Can anyone tell me what might have been the detailed route for our
RNO-SJC flight today, Mon 28 July, 1:00 to 1:55 pm (in terms of common
geographic waypoints or GPS coordinates)?

I'd always had the impression these flights departed RNO heading more or
less straight west and passing well to the north of Lake Tahoe and even
Donner Lake, then angling southwest toward San Jose; and it seemed to me
that was what we were doing today, though with the fairly severe haze
and smoke currently in the Tahoe area, I couldn't pick out any Tahoe
landmarks (looking across the Lake this morning, one couldn't see the
far shore even in the narrow direction).

About half or a third of the way into today's flight, however, from
23,000 feet we saw an obviously large fire zone area (no visible fires,
but large area of heavy smoke) almost under our flight path on the left
side of the plane, and easily visible in the middle distance was what
sure looked like Half Dome.

I kept thinking we really wouldn't have departed that far east and south
of a straight-line path from Reno to SJC, and that this must have been
one of the less publicized fires in the region NW of Highway 80; but on
the other hand we ended up (with minimal banking and turning that I
could sense) coming up into SJC up along what I took to be Highway 101
from the south.

Would our route really have passed that close to Yosemite?
