Dirty Harry's road shows what the combination of Northwest weather and bad drainage can do. Much of the road has turned into a creekbed, but things have gotten so bad that it's becoming good. In many stretches of the road, there's now a deep gully in the middle of the road that captures all the runoff. Hikers have created a relatively rock free trail along the side of the road. In constrast, the middle section of the road to the Balcony has good drainage and is covered with smooth dirt and pine needles, pleasent to walk on.
The other good news is that volunteers have cut many trees out of the road. All in all, its not a bad hiking experience, much better than it was a few years ago.
From the trailhead (elev. 1380'), the road ascends a peaceful forested side canyon that blocks I-90 noise quite well. After 1.5 rocky miles, the road passes the side trail to Dirty Harry's Balcony; the junction is well marked with ribbons and cairns. I continued on up the road, enjoying the sun and warmth of this exceptionally fine spring day. Museum Creek was running vigorously (elev. 3000') from snowmelt. It's a great place to rest and has a good view of McClellen Butte.
But the high country beckoned and I continued the climb. The road was free of snow up to the Talus View junction at 3400'. Above the road is a huge talus slope that offers a nice sunny viewpoint if you climb the rocks a little. Snow-phobic people should stop here, because at the next switchback at 3800' serious snowpack begins. I waded up through the semi-consolidated snow, following some old footprints. These gave out at about 4000', and it was tough slogging up the final few hundred feet to the summit of Dirty Harry's peak, 4680'. The deep snow up here will take a month to melt, at least.
Great views from the summit, of course, although the wind was strong, and my hat nearly took a thousand foot free-fall down to Granite Lake; luckily a fir branch caught it at the brink of the cliff.
Maintainence needs: Somebody needs to hike up the road with some tools and dig drainage dips in the road to get the water to run off. Some lopping and cutting of branches would also be great.
