What is the quality of the map currently?
Trails are drawn from pictures and some 2 year old GPS traces. We were very active in this place 2 years ago when a small training adventure race was put on.
Contours are from USA 10 meter grid DEM. That means that the smaller re-entrants are clearly missing.
Vegetation is as it is seen from pictures and not 100% correct thus. I believe the map is usable for training purposes. White vegetation is rough open land.
Rocks are guesses from the satellite pictures again.
This is how to get to the start area from Seattle.
The area is quite rattlesnake infested, but I expect that they are still quite passive at this time of year.
