The County’s extremely varied topography ranges from sea level to 14,410 feet at the summit of Mt. Rainier (see Map 2-2). There are 118 square miles of water in the County excluding Puget Sound. Puget Sound divides the County into western and eastern portions. The smaller portion, to the west of the Sound, is composed of two southward trending extensions of the Kitsap Peninsula. In addition, a number of islands, seven of them inhabited, in the southern Sound are incorporated into the County. The developed portions of the County are located near Puget Sound on gently rolling terrain formed from glacial outwash, till and sediments deposited by the rivers in the valleys. The eastern portion of the County consists of foothills rising up to the crest of the Cascade Range. Just to the west of the crest is Mt Rainier, the high point of the County and of Washington State. Mt. Rainier National Park encompasses the southeast portion of the County and is a prime recreation and tourist attraction. Commencement Bay is an arm of Puget Sound and the location of Pierce County’s principal port, the Port of Tacoma. This deepwater port is one of the largest on the West Coast of the United States. The water from all major rivers having headwaters on Mt. Rainier, with the exception of the Cowlitz and its tributaries draining the southeast corner of the mountain, flows into Puget Sound at Commencement Bay. These include the Puyallup, White, Nisqually, Mowich, and Carbon Rivers. Of these, only the Nisqually and Puyallup actually enter Puget Sound. The White, Carbon, and Mowich Rivers are tributaries of the Puyallup. The White River borders the northeast and east sides of the County draining the east side of Mount Rainier. With its tributaries, the Mowich and the Carbon, the Puyallup River contains the runoff from both the north and west sides of Mt. Rainier. It discharges their combined waters into Commencement Bay. The fertile Puyallup and White River valleys that once supported a major agricultural business hub are giving way to commercial expansion. Warehousing and distribution facilities are now beginning to predominate where crops used to grow. The Nisqually forms the southern border of the County and drains the south side of the mountain. The major features along its reach are Alder and La Grande dams. Its major tributary is the Mashel River. Other water features include 361 lakes greater than one acre in size. Hundreds of streams and small rivers drain the rest of the County either into larger rivers or directly into Puget Sound. There are 225 miles of saltwater shoreline surrounding Puget Sound. Although greatly depleted from their previous existence, covering most of Pierce County, the forest still predominates in some of the eastern and southeastern portions of the County see Map 2-3. PAGE 2-4 REGION 5 ALL HAZARD MITIGATION PLAN – 2015-2020 EDITION BASE PLAN Anderson, McNeil, and Fox Islands are the three major islands within the County and lie in the southwest corner of the County. Anderson and McNeil Islands can be reached only by ferry or boat. There is a connecting bridge to Fox Island. Four smaller islands: Ketron, Raft, Herron, and Tanglewood also have a small number of permanent residents. Ketron and Herron Islands are accessed by ferry. Raft Island is connected to the mainland by a bridge and Tanglewood’s four homes are reached by a very short boat ride.

The last major glacial period, the Fraser glaciations, lasted about 10,000 years. The advance of the Cordilleran ice sheet from British Columbia into the Puget Sound area reached its maximum extent around 15,000
