"I conquered Dirtybox peak in the usual way, by traversing the ridge from Mailbox. I then bushwhacked down the north side. I was hoping to find a couple old forest service roads, about 700 ft below the summit. Unfortunately, I just found a lot of rocks strewn about in a relatively open area. I suppose these were once used in the embankment of the roads, but I did not succeed in following these roads very far (see map). Eventually I gave up and just headed through a relatively open area going north and down. This turned into a steep streambed - it's the one descending more or less directly under the summit. I could see it easily looking back from the Granite Creek Trail, once I got down to it. I considered going down a ridge, rather than the gully, but it looked more likely to have cliffs. The gully was very steep in some parts, but it never left me at the top of a waterfall. I could always make my way down, though some of it was very heavily congested with blackberries (or something similar) and devil's club. My leather work gloves were handy; long pants were essential. I was surprised how long it took - 4 hours to go down about 2000 feet. The water situation was inte..." — markgarrett • Aug 27, 2017

"We planned to do a ski trip, but rain and high avy danger convinced us to cancel. Instead we did Mailbox and crossed over to Dirtybox. It drizzeled off and on.

"My buddy Paul and I have had a bit of a vendetta against West Defiance Ridge ever since we attempted to traverse it from Mailbox Peak to Mount Defiance 2 years ago and had to bail and head Down Dirty Harry's Peak disappointed and in fading light. The problem that day was very poor visibility due to thick, low cloud cover, which made our route finding completely reactive to what the ridge presented to us in the moment at hand. This caused much delay and even considerable amounts of backtracking as we made our way from Mailbox Peak nearly to Web Peak before turning back and taking the trail down Dirty Harry's Peak. Today's weather called for sunshine and temps in the upper 80s, so we were confident the route finding should present no problem, but were anticipating a very hot day since we were to be exposed to the sun nearly the entire way between Dirty Harry's Peak and Mount Defiance. Despite knowing what we were getting ourselves into, I still failed to fully prepare myself for the heat. 6 liters of water/Gatorade for 6 peaks did not cut it. Anyway, without further ado lets jump into the trip. First up was Mailbox Peak. No big deal. Some good conversation and we were th..." — Al-Rashid • Aug 10, 2014
