Soaring in Owens Valley

Team Tuno did a vehicular excursion through Southern California over
the weekend which included the stretch of Hwy 395 from Lee Vining
south through Bishop and Inyokern.

I'd heard of Owens Valley a few times in soaring write-ups, but
driving through it, I was amazed at the geology, with the Sierra
Nevada on the west side and the White and Inyo ranges on the east.
Someone, I can't recall who or where, wrote a piece somewhere
specifically about soaring this valley and its ranges. (It talked
about convergence zones in the valley.) Can someone point me to the
article? I tried Google'ing for it but came up empty.

Also, is there a commercial gliding operation at Bishop? I recall JJ
mentioning Region 11 contests there, but the SSA "where to fly" page
doesn't have anything for Bishop.
