That would be 282 feet below sea level at Badwater in Death Valley.
It’s the lowest point in the Western Hemisphere, but this map shows some of the lower ones.
You may need to zoom in on this photo to see it clearly, but there’s a sign up on that cliff that shows where sea level is.
That’s not snow, of course. It’s salty sand, and it was an odd texture upon which to walk.
The place really did have an otherworldly feel to it.
This quick tour of Death Valley whetted my appetite for more, and I’m looking forward to taking a couple of days to explore it!
