Inspired by WW7D's recent Activation of Humpback Mountain, I decided the relatively short drive to the Humpback Mountain trailhead was perfect. From my home in Bothell, Exit 47 on I-90 takes me about 45 minutes to reach. I've hiked numerous peaks in the Snoqualmie Pass area, but had never hiked Humpback. Access to the trailhead was as described in WTA's hiking guide.
