I launched at 1pm from Marshall and the wind was 7 mph SE. Reached 6k. Around 2:45 pm at Marshall height, the wind was 9 mph from the East, so it was like flying a different site, with a bit of ridge soaring on the East side of Cloud Peak. By 3:30 pm the wind came from the South and there were wider/smoother thermals up to 5300′.
The East wind component likely delayed the arrival of the smog, explaining why the altitude gains were better than expected.
The “flying tank” is full again. Merry Christmas to all.
