Today's sailplane flight was marked by the heavy smoke from nearby forest fires, making visibility poor (less than 10-15 km at times). I had to take a 2000m (7000') tow way into the back range in order to find any lift at all. Only once I had reached the inversion, at just under 3000m, was it possible to release and climb up to cloudbase at 3600m. Later I got as high as 3850m and was able to cross the valley to the edge of the Purcells, but the smoke was thicker there and I got shot down.
Here's my flight track:
There are a few pictures from the day on the same website that's hosting that flight track, mtbguru.com. Click on the little camera icons on the flight track to see the picture that was taken at that location.
The flight is also logged at paraglidingforum.com, and on the OLC.
