I did see an interesting phenomema about 20 minutes into the climb:
there was a huge area of dust that either was wind driven or maybe it
was a rotor touch down, but there was a huge area that was nothing but
dust that was being stirred up North-East of Reno that was quite
visible from about 20K feet.................. I was in a Dash-8.

At a presentation at the 2008 Experimental Sailplane Association
(western) meet, met man Scott Willey gave a blow by blow presentation
on the lead up to and the flight itself from Bob Harris record wave
flight (February 17th, 1986, 49,009'). One of the key characteristic
features considered to be a req for any type of record wave flying was
the telltale dust plume you observed.
