Thanks.

No problem. I'm happy that someone is out there checking things are accurate, I've been on several wild goose chases in the past.
Keep up the good work.

Hi Peter,
Because the stream is also not on the map. It could be that the stream isn't permanent, but I doubt that. It was large enough to assume it's a permanent feature. I think a cascade of a 20m is more accurate. A waterfall is an extreme description, but I can assure you it's there.
