The virtual posted coordinates are good for parking but the final container is not there, it is within 0.9 miles. A mirror makes for a great TOTT, but not for the final. You need a 6'+ tall TOTT for that final at N 42° 5P.PPP' W112° 2P.PPP'
To crack the mystery of the PPPP PPPP, use your mirror on the red chunk, turn it to ppp ppp, use the mirror on your adjusted red chunk again, then solve all the PPPP PPPP both red and blue chunks. The next step awaits in that link.
The 1st puzzle is pppp... Pig Pen. There's a picture in the gallery that explains the letter substitution so you don't have to hunt the web (there are some variations). For the first chunk, use the mirror horizontally above the text to reflect it into the reflected letters. Turn it into pigpen, then use a mirror horizontally above the pigpen text you just made to reflect it a second time. Now read off that pig pen and convert it back into English.
Solve the puzzle and you get a keyboard. Now you just gotta match the image of different font PPPPPPPs near the top of the cache page.
Extra hint: PPPP PPP PPPPP PPPPPPP PP PPP PPPPP PPPP? you only use the mirror on the red side and it first turns into pcacdc. Now turn that into pigpen.
