Secret message 2 miles from the US top secret bunker entrance

Here's an entrance to the top secret hardened military command and control center inside Cheyenne Mountain in Colorado, USA.

Just to the west of it are the slopes of the mountain, beautiful pristine woods.

Looks like lots of trees, unadulterated hiking space, upon zooming in.

But what's that there? Tree openings on the landscape that spell USA?!

Go USA! Someone probably peed one too many times on the trees there to mark their territory.  But what are those faint nonrandom curves to the right? There's more writing.

Someone wrote "USA LOOSER" on Cheyenne Mountain land, just 2 miles from the top secret bunker entrance. (I did have to use a couple of filters to make out the "looser" part of the message)

Either the 3-letter agencies aren't doing their jobs and the US isn't secure, or they are complicit in this and the US isn't secure.
