2020 Aug: Spray Park–Knapsack Pass Loop trail, Mt Rainier NP

After a dozen hikes to Spray Park splendor since 1982, in summer 2020, I discovered an adventurous loop return to Mowich Lake via Knapsack Pass Trail (see Washington Trails Association), in Mount Rainier National Park. However, slippery exposure on steep scree and snow scared my wife Carol, who vowed never to hike Knapsack Pass again! (6.7-mile circuit with 2600 feet gain.) Fortunately, steps postholed in soft snow allowed crossing safely on that warm day (August 17th). I delighted in this flower-filled loop under the snow cone of 14,411-foot Mount Rainier.

Beware, the unmaintained and unmarked Knapsack Pass Trail exposes hikers to steep scree and year-round snow fields which could become dangerously icy. The trail is best navigated by experienced hikers only, in late summer using a good map, GPS device, and trekking poles (or ice axe if icy). The worn trail, marked with cairns and boot tracks, may become difficult to follow in the half mile of scree and snow fields southeast of Knapsack Pass.

A mountain memorial for David Dempsey in Spray Park

While bicycling on May 8, my older brother Dave sadly lost his life to a negligent motorist along Highway 32 in Chico, California. In the field of flowers pictured below in Spray Park, Carol and I spread some of Dave’s ashes:

From familiar Spray Park, our counterclockwise circuit entered territory unknown to us, in the headwaters of Cataract Creek above Mist Park (pictured below). If conditions became too rough, we were okay with turning back.

Crossing several steep snow fields made us nervous, perched above sharp rocks:

Then we steeply ascended sharp scree and switchbacks to Knapsack Pass, a small notch in Mother Mountain:
