The cache container is a small Lock&Lock container. The
location is on the Old Cascade Highway at a foot-bridge over the
Tye River. This road use to be the old Stevens Pass Highway many
many years ago.
I suggest approaching the cache from the top of
the pass, as the road is much more scenic that way. However it
can also be reached by taking the lower approach. If you are
really adventurous, and have a high clearance vehicle, you can
take the spur that heads down the cliff half way up the pass.
It was passable with my Ford Ranger 4x4 Pickup.
Please post the coordinates you get when you find the cache. I
had two GPS's units with me and they were both giving me some
pretty wild readings. The above is somewhat of an average of what
they both told me.
