Cache is not at posted coords but follow the instruction to the final destination. You must be really tall to reach this cache. A TOTT is required but not a usual one. If you get lost the final coords are in the hint.
The posted coords will take you to a parking lot. From there proceed to the green gate about 76.23 meters away (N 49 16.146 W 122 44.002). From here you can go under , over or around the gate but you must get by it to proceed. Go about 75.08 meter down the trail to a sign board (N 49 17.124 W 122 43.950) . Stop here to get your bearing as you are very close. Travel another 50.15 meters down the trail . From here do as the Friendly Giant used to say "Look up ... waaaaay up!" . I hope you have a tall partner or muggle helper and/or brought the proper TOTT.
Bring a pen, be nice to the enviroment and watch out for wildlife.
