I was dropped off at the Rattlesnake Lake Trail Head for the John Wayne Trail at 11:30 on Wednesday.
The road surface is very coarse gravel (several inches deep in places) with fist-sized rocks occurring quite frequently.
The next morning (today) I entered the dark hole that is the west portal. Almost immediately, I could see the light at the end of the tunnel--2.2 miles away! The east portal is the white spot in the lower center of the picture--the white spots on the left and right are reflectors along the sides of the tunnel.
After a relatively short 20 minute ride, during which I was 'rained' on by water seeping through the hundreds of feet of earth above me, I arrived at the east portal.
After being battered by the increasing number of rocks for 20 miles, I decided to call a halt when I reached Easton. I was going to ride the remaining 12 miles to Cle Elum on the freeway, but as luck would have it, Frances was only five minutes behind me on her way home from Tacoma. Thus ended my jaunt through the tunnel; it was a good experience but not one that I would want to do again--I'll stick to paved roads from now on!
