Denver sits at 5,280 ft on the South Platte River where the high plains meet the Front Range, and the areas we route requests to ring that one metro: Aurora east across I-225, Lakewood and Arvada west toward the foothills, Thornton and Westminster north, and Highlands Ranch south into Douglas County. The ground under all of it is Denver-series clay, and the winter is the other half of the story - a 36-inch frost depth and a decade of de-icing salt on the same slab.
