Fairway Social already has this map. Start a round and it sets up the card for you — pars and stroke indexes — so you can score it hole by hole. Clubs use the same map for their events, and members score from any phone.
Fly Mount Si Golf Course in 3D
The course on real terrain, every hole's line of play drawn on it. Pick a hole and fly it from the tee, or tour the whole course.

Par comes from OpenStreetMap and is unconfirmed against the club's scorecard.
Stroke index comes from the same source and is also unconfirmed.
Straight-line tee to green centre, summed across all 18 holes: 5459 m. That is a measurement of the map, not the course: a dogleg plays longer than the line across it, and the mapped tee is one point rather than a named, rated tee block.
Line of play is measured along each hole's routing line as mapped in OpenStreetMap — the tee, the mapper's corners, then the green centre — so it follows a dogleg where the straight line cuts across it. Every hole here has one. Neither number is the club's scorecard.
Every hole
Shapes only — tee, fairway, bunkers, water and green — drawn from OpenStreetMap. No aerial or satellite imagery is loaded until you open the 3D course above. The dashed line is the hole's mapped line of play where it has one, otherwise the straight line from the mapped tee to the green centre.
