At 9:15 I started from the parking area near exit 38 E outside of the gate. I walked up road to Dirty Harry's Logging Road, and took the trail off of the logging road towards Dirty Harry's Balcony (the trail is marked by an old Pennzoil can on the end of a stick). Soon the Dirty Harry's Balcony trail splits, to the right (west) is the Balcony, I went left (east) on a nice trail which is not on the map. A couple miles east this trail forks (near some large rocks with McClellan Butte at approximately 215 degrees), the upper fork leads to Putrid Pete's Peak (West Defiance) and the lower fork leads to the Mason Lake trail head. I headed towards Putrid Pete's Peak. After a mile or so of switchbacks I broke out of the trees, ahead was a long, steep ridge with many patches of snow. From there it was a tough, steep scramble without a trail, soon even the orange trail ribbons petered out (whose numbers until then were uncountable). No worries, I needed to do was burn through all my reserves of energy going straight up to the peak.
There's a little plastic box at the top with a photo (of Putrid Pete?), some poetry, and a registry. There are also some very nice views. I considered continuing across the ridge to Mt Defiance, but decided it looked too slippery with snow/rocks, maybe later in the year.
The trail was fairly unpopulated, it was nice Sunday and I only saw three other people on the trail. The ridge scramble is not something that I'd be comfortable doing alone. Not only is the final ascent fairly untraveled, but it is steep and has poor footing, you may fall for a while before stopping, or you may simply twist your ankle while coming down. I would not have gone up to Putrid Pete's Peak if I hadn't met another hiker on the trail with the same goal.
I returned to my car at 5:30 PM.
