Jack Mountain Professional Guide

Detailed Trail Description from our Guidebook

"Jack Mountain stands alone like a citadel, big and mean-looking, dominating all the peaks nearby. One of the 10 non-volcanic peaks in Washington State over 9000 feet high, Jack towers above Ross Lake as a sheer profile in the sky rising nearly 8000 feet in just three miles. There is no easy way up this colossal hulk; indeed it has the reputation of being one of the most demanding and nerve-wracking ascents in the entire Cascade Range. Jack has therefore been relegated to the category of “nasty peak” and is less often climbed than many of its cohorts."
