Hoover Dam Contour Map

Key Takeaways

  • The Hoover Dam Contour Map showcases the topography of the surrounding area.
  • It provides valuable information about the elevation levels in and around the dam.
  • The contour lines on the map indicate areas of equal elevation.
  • This map is useful for understanding the geography and planning various activities.

History of the Hoover Dam Contour Map

The Hoover Dam Contour Map, also known as the Elevation Map, was created during the construction of the Hoover Dam. Built between 1931 and 1936, the Hoover Dam is a concrete arch-gravity dam located in the Black Canyon of the Colorado River, on the border between Arizona and Nevada.

During the dam’s construction, it was crucial to have an accurate understanding of the area’s topography. The contour map was developed to visualize the elevation changes of the surrounding terrain. By analyzing the map, engineers could plan the construction process, identify potential challenges, and ensure the stability and effectiveness of the dam.

Unique Insights from the Contour Map

The Hoover Dam Contour Map offers several unique insights about the area:

  • The contour lines on the map indicate areas of equal elevation. The closer the lines, the steeper the slope.
  • The contour map demonstrates the significant elevation changes around the Hoover Dam, with the highest elevations found in the adjacent mountains.
  • By studying the map, one can observe the gradual decrease in elevation as the distance from the dam increases.
  • The contour intervals provide valuable information about the vertical distance between each line, allowing for a precise assessment of the terrain.
  • Knowing the topography helps in understanding the flow of water and designing efficient water management systems.
