"Another week, another hike up Mailbox with AK. This time, however, with a quick peak at Dirtybox. Really enjoyed the scrambling after the leg work. Cloudy and in the high 40's, parking lot was insanely overflowed" — zachmitch • Jun 1, 2024

"JC and I, our first hike together since 2020. At the trailhead at 6:45am. Cool and cloudy, high 40s. Enjoyed a quiet trail up the old on Memorial Day weekend Monday. Hike down was much more crowded. Glad we showed up early!" — zachmitch • May 27, 2024

"Mailbox up the old trail, down the new with AK. Started early and managed to beat the heat on a busy Mother's Day hike. Down in back in ~4.5 hours. Not a cloud in the sky, 88F. Snow was minimal, walked probably 20 total steps on snow." — zachmitch • May 14, 2023

"A really cool peak. Got to the trailhead well before sunrise and took the old trail to the summit in the snow for sunrise. Overall rating 7/10, definetly recommend hiking it at a time where you can have the trail to yourself and enjoy the view" — MountainQuest • Jan 26, 2023

"A classic summit. Ran to the trailhead from North Bend and took the Old Trail to the top. Overall rating 8/10, amazing views, close to town, and a fun Class 3 scramble to the top of the Haystack" — MountainQuest • Sep 27, 2022
