There are several terrain spikes in Patagonia in the reagion around the airport SCPY. This is also the region where the famous loading splash screen was taken (the one with the Cessna) and ironically this spectacular view is now also ruined through a massive terrain spike!!
The image with the camera setup dialog is the one showing the lake and mountain from the loading screen!
Follow the flight Plan provided and you will encounter the first spikes in the first quater of the flight plan (starting direction: south) in the mountains.
