Canadian Rockies - oddities

Flying Along the Frazer River from Vancouver then following the Mackensie River to Kamloops I came across these apparent structure.

Additionally many of the roads were at very weird inclines that would require to drive along a road angled at 60 degrees plus across the carriageways.

Is this something others have enbcountered?

These terrain spikes are well known.
Here is a link to one of the earlier posts on the issue.

Spikes have been addressed and will be fixed in next update.
