After putzing around a bit on my own with how the coordinate system works, I figured out the location. No need to fly (unless you want to). Use the following cheat code:
cheat setplayerpos -97500 -51700 46000
This will spawn you close to the correct point. Walk around a bit, or go down a slope a little. I think the game wants you to go down a little to go back up to the point.
