Interesting terrain in FS9 default scenery.

[kvuo]

If you have default FS9 scenery installed, here's something interesting.

Take off from KSGF, intercept and proceed northwest on the SGF 310 radial to about 20dme. descend to about -12000 MSL (yes, minus
12000). you will find a lake.

I remember there used to be another big hole in FS2k (or maybe it was 2k2), near Fallon, NV, but this one takes all! Oh, there's also a
mountain spire I found once somewhere in venezuela thats like FL600...

any others anyone has found?
