Diamond Altitude via thermal in the US?

It has been done in thew Eastern US by a number of pilots, including
myself, from the airport at Marion, NC, using thermals off the
foothills of the Smokies to link up with the wave from Mt. Mitchell.
There were numerous wave camps there during the 1970s and 1980s.

I'm reminded I did this some years back after damn near
landing at Furnace Creek (Death Valley). I thought I had
a trace below sea-level but when I checked it I was slightly
above. Cloudbases down towards Las Vegas were at 18k.
It would make a better story if it was intentional !

PS: Do NOT try soaring in the Saline Valley.

You only need to fly out to Gila Bend (778 msl), pull
the spoilers out until you're under 800 ft agl and
then thermal up to the legal limit. I tried this once
but after circling around the Gila Bend airport for
half an hour at low altitude looking for lift decided
it just wasn't that important to me.

is at 1600', and
I've seen cloudbases above 22,000' (FL220) on a good
day up by the
Grand Canyon (an 'easy' 2-3 hour flight from Turf).

There has been some talk of arranging for a 'Thermal
Window' that would
make this easier to do.

Furnace creek! Hehehe. 210 below sea level. I played
golf there once. The coyotes were fighting the rattlesnakes
for shade. I looked like a wet tea bag from the sweat.

YO! Good for you getting back up and away from there
