Even though it boasts one of the most memorable names in the I-90 corridor, Dirty Harry's Peak remains relatively unknown. Or at least relatively unhiked. Which is great news if you're looking for a challenging route near Seattle without all the foot traffic that's typical in this area. Yes please. That said, don't expect manicured trails here – most of the route follows an abandoned logging road, which is certainly befitting, considering the peak was named after Harry Gault, a former logging baron of Snoqualmie Valley.
