"Great day in the mountains with GM, his first hike/peak in Washington. As an avid runner, I knew he'd be able to handle the effort, but he was open that heights would be a factor (he's from Indiana/Michigan). I was proud that he overcame his fear and scrambled all the way to the top section with me. Unfortunately a series of fires left the view a bit wanting, but it was still an overall nice day -- and we had the top to ourselves the entire time. Quickly down, followed by some teriyaki make for some nice memories. Thankful." — zachmitch • Aug 10, 2024
"Some sections past the Ira Springs connector were pretty overgrown. Also, getting to Dirtybox from DHP would have involved climbing down about 15 ft or so on a rope, so I decided not to. I'll try Dirtybox from the Mailbox side instead." — mathiasricken • Jul 21, 2024
"Decided we wanted some off-trail fun close to home and boy did we get that. AK and I started at the lower Tinkham Road trailhead @ 7 am and found our way back there about 10 hours later. We created a loop which had us on top of 6 different peaks, a single day PR for me (in order): Dirty Harry's Balcony, Dirty Harry's Peak, Coincidence Point, Webb Mountain, P3, Defiance. It was extremely slow going between Dirty Harry's Peak and Webb Mountain -- maximum bushwhacking and negotiating the endless boulders on that thing was exhausting. My favorite part was probably the traverse between Webb and Defiance. " — zachmitch • Jun 29, 2024
