[OSM-dev] Holes in contours

[Gregory]

I noticed the Cycle map has a small hole on that link, here it is zoomed in:
http://www.opencyclemap.org/?lat=49.61624&lon=-114.41811&zoom=16&layers=B000

It is one of the holes on Piste Map:
http://www.openpistemap.org/?lat=49.61624&lon=-114.41811&zoom=16&layers=B000

I don't know if this helps you discover what the problem is.
On the cycle map there is also a small hole closer to Highway 3.
