Geographical Dangers in Washington

Home to breathtaking scenery and a variety of natural hazards, Washington is at the northwest corner of the continental United States. It's bordered by the Pacific Ocean to the west and Canada to the north. Washington's varied terrain features rain-soaked forests along the Pacific, high mountains, deserts and grasslands. However, visitors to Washington should be aware of some of the dangers presented by the awe-inspiring landforms.

Columbia River
- The Columbia River flows 1,200 miles from southern Canada to the Pacific Ocean.
  
  The Columbia River, forming much of Washington's southern border with Oregon, is a popular destination for outdoor enthusiasts. On the lower reaches, hydroelectric power has created a calmer river than would otherwise exist. Upstream, steep gorges and powerful rapids invite hikers, climbers and boaters to the region. The stunning scenery is also dangerous. Tall cliffs are a constant hazard, as are the pounding rapids. River currents are often strong and can overpower even strong swimmers. In springtime, snow melt leads to higher river flows, so visitors should take this into account.
Volcanic Activity
- Washington contains several active volcanoes.
  
  Several active volcanoes dot the Cascade Range that runs north to south through western Washington. Mount St. Helens erupted in 1980, demonstrating the raw power contained within the Earth. Other ticking time bombs include Mount Rainier and Mount Baker. An eruption of Mount Rainier like the one at Mount St. Helens would put the population centers of Seattle and Tacoma at risk. The volcanoes in the Cascade Range belong to a variety that erupt with extreme violence, blasting gas and rock miles into the sky.
High Mountains
- The Cascade Range encompasses true wilderness.
  
  The peaks of the Cascade Range are snow-capped and rugged, generally rising more than 2 miles into the sky. Mount Rainier, the highest mountain in Washington, stands an impressive 14,411 feet above sea level. For climbers, the hazards presented by these mountains are clear. Snow, ice and jagged rock obstruct any path to the summits. For the average tourist, sudden blizzards can strike the foothills and mountain passes, making travel impossible. Keep a well-stocked car emergency kit when traveling over the Cascade Range.
Desert
- The region just east of the Cascades receives very little rain. The mountains absorb all of the moisture coming from the Pacific Ocean, leaving a rain shadow on the eastern slopes. Some places receive only a few inches of precipitation each year. In the summer, temperatures can soar above 100 degrees. Visitors should be prepared by carrying ample water; dehydration can sap strength and muddle thinking much faster than a lack of food.
