Seattle, the 'Emerald City', is a place of natural beauty and human ingenuity. But what makes this city so unique is the story behind its landscape. The hills and basins of Seattle have been sculpted by glaciers and modified by humans, creating a city that is both breathtaking and fascinating. In this article, I will explore the history of Seattle's landscape, from the glacial forces that shaped it to the human projects that have transformed it. I will also discuss the city's nickname, 'Emerald City', and the natural beauty that still exists within its limits. So, let's dive into the story of Seattle's landscape and uncover the secrets behind its unique character.
A City Shaped by Glacial Forces
Seattle's landscape is a testament to the power of glacial forces. The broad contours of the city's landscape and the water around it owe their shape to the advance and retreat of glaciers during the last ice age. The Puget lobe of the Cordilleran ice sheet covered the area in a mass of ice up to 3,300 feet thick. The glacier scoured the basins now occupied by Puget Sound and the region's lakes, leaving behind a landscape that is both beautiful and challenging. The ice also transported large boulders called glacial erratics from more northerly locations and deposited them around the region, creating unique features like the Wedgwood Rock.
One of the most interesting aspects of Seattle's landscape is the presence of drumlins. These elongated mounds of glacial debris run north-south, parallel to the direction of the ice's movement. East-west travelers in the city, facing challenging ups and downs, may attest to this topographic trend. The presence of drumlins is a reminder of the powerful forces that shaped the city's landscape thousands of years ago.
Human Projects and Alterations
In more recent times, humans have undertaken projects to rework the topography of Seattle. Notable alterations include leveling Denny Hill north of downtown and filling in tideflats at the mouth of the Duwamish River south of downtown, which created around 1,300 acres of new land. Seattle's professional sports stadiums sit atop this fill. The city's waterfront has also undergone significant changes, with new ferry docks, seawalls, and tunnels created to improve public access and update infrastructure.
The replumbing of the region's waterways is another example of human ingenuity. In the 1910s, the Army Corps of Engineers built canals on either side of Lake Union to connect Puget Sound with Lake Washington. This project created a new connection between the two lakes and allowed for the raising and lowering of watercraft between the freshwater lakes and tidal Puget Sound. As a result, Lake Washington's water level dropped about 9 feet and ceased draining from its natural outlet at its southern end.
The 'Emerald City' Nickname
Seattle is often referred to as the 'Emerald City' due to its lush, green look. The city's parks and tree-filled neighborhoods lend a lush, green look to the metropolis, while tall buildings downtown cast long shadows and ships navigate surrounding waterways. Pockets of old-growth forest still exist within city limits, containing centuries-old trees such as Douglas fir, Western red cedar, and Western hemlock. Seattleites often spot wildlife such as bald eagles, coyotes, and sea lions in the city's various habitats.
What makes Seattle's nickname particularly fascinating is the contrast between the city's urban landscape and its natural beauty. The city's hills and basins, shaped by glacial forces, provide a backdrop for the lush, green spaces that make up the 'Emerald City'. The human projects that have transformed the city's landscape have not diminished its natural beauty, but rather enhanced it, creating a unique and captivating urban environment.
Conclusion
Seattle's landscape is a testament to the power of both natural forces and human ingenuity. The city's hills and basins, shaped by glaciers, provide a backdrop for the lush, green spaces that make up the 'Emerald City'. The human projects that have transformed the city's landscape have not diminished its natural beauty, but rather enhanced it, creating a unique and captivating urban environment. As Seattle continues to evolve, its landscape will continue to tell the story of the forces that have shaped it, both natural and human.
One thing that immediately stands out is the contrast between the city's urban landscape and its natural beauty. This raises a deeper question: how can we balance the need for urban development with the preservation of our natural environment? In my opinion, the answer lies in finding a harmonious relationship between the two, where human projects enhance rather than diminish the natural beauty that surrounds us. From my perspective, Seattle's landscape is a perfect example of this balance, and it is a testament to the power of both nature and human creativity.
