This is a shot taken from the top of Mt Evans in Colorado.
Mt Evans is a 14er, or is 14,000 ft above sea level.
This specific spot is at an elevation of 14,200ft.
From this height, you can easily see for miles and miles. Even all the way back to Denver, if you are looking in the right direction.
This vantage point allows for some spectacular views of the Front Range of the Rocky Mountains below it.
In this specific shot, you can see Summit Lake below.
