Mount Margaret Professional Review and Guide

"This hike climbs through the blown-down but slowly rejuvenating forest from Norway Pass Trailhead to Norway Pass, then follows the very spine of the Mount Margaret Backcountry to the summit of Mount Margaret. Mount Whittier is a short but challenging optional side trip. This entire hike is over strata that are part of the twenty-millionyear-old Spirit Lake Pluton. Intrusive rock is magma that has cooled and solidified below the earth’s surface.

A pluton is a large body of intrusive rock, possibly several miles or more wide. Much of this pluton was deeply eroded by ice age glaciers that melted only about 11,000 years ago. They formed the deep U-shaped valleys and bowl-shaped glacial cirques that are so evident here today. Of course, there are deposits of pumice and other recent volcanic material from Mount St. Helens thinly covering much of the terrain. The higher peaks have been mostly washed clean, however, and the rock of the pluton is exposed."
