Billy Frank Jr. Nisqually National Wildlife Refuge Professional Review and Guide
"Far from its glacial source on the southern side of Mount Rainier, the Nisqually River empties into Puget Sound in a broad delta. Once a working farm, the site has become one of the finest birdwatching locations in the Puget Sound region, although many people come purely to enjoy the natural setting. Whether looking specifically at the birds or not, hikers will find an interesting walk that explores a wide range of habitats and wildlife.
Fiery beginnings from beneath the Earth’s crust, the evidence at Pinnacle Peak is more subtle, found in interesting columns of extruded rock near the summit. And although at only 1,800 feet it hardly qualifies as a significant climb, it's visibility and prominence in the Enumclaw region give Pinnacle Peak a certain “because it’s there” satisfaction to all who
have reached the top, no matter how easy the trip might be."
