Just offering my speculation on the tasks and the order.
Router marker - Airport to Douglas boar harbor - boat ride up Taku river to the Grizzly Bar
Roadblock - Drop markers from the bush plane. (The target is just to the right of the word bar in the picture)
Router Marker - Next they made it over the the lake departure spot and boarded helicopters to Norris Glacier. ( the line between the points on the map show the flight plan of the helicopters)
Router Marker - Once on the Glacier, the pair went down into an ice cave to discover the next clue.
Router Marker - use the ladder crossing to make it to the other side to chip out your next clue from the ice.
Router Marker - take the Boat back to Douglas boat harbor and make you to Blueberry hills. ( I think the teams did all the tasks together on the Ice)
Roadblock - memory task inside the structure built and surrounded with plants and trees at the top of Blueberry hills.
Router Marker - Make your way to Outerpoint trail and race to the final mat!
Just have a hunch that the teams were always together on the ice...
Can't wait to see it!!!
in the caps 4 and 5, the picture shows Norris Glacier in the background the face of the Taku Glacier, this picture was taken along the line between lake departure and lake access.
Caps 6 and 7 are the face of the Taku Glacier. Caps 5 and 9 show teams in the Ice Caves.
In the Caps that show the plane leaving the target, did you notice all the people on the ground just to the left of the target?
