As a big geography nerd, I have always wanted to go stand on the four corners. I knew it would probably be underwhelming and that I would likely have to stand in line to stand in the spot, take a quick picture, and move out of the way. What I didn't expect was to have to pay $5 per person, cash only, to do it. I guess they figure they have got you; you drove all the way out to the middle of nowhere (luckily it was on our way to Mesa Verde) after all. It is run by the Navajo Nation which is in a remote area, so you can't really blame them for trying to find ways to make money in such a desolate place. They have built this big concrete pavilion to surround it and make it look like more than it is. There are plaques talking about how the surveyors made the border lines. Interesting, but not $5 per person interesting. Surrounding the pavilion are several stalls for Native Americans selling crafts. There are pit toilets but it looks like they have almost finished a much nicer bathroom area so maybe it will be open for 2016. A fry bread stand sells food. We arrived close to sunset so most of the stalls were empty and the frybread stand was closed but there weren't too many people at the monument which meant we could take a bit of time on the actual Four Corners before another family showed up.
I have to admit - this took us a good eight hours out of our way on our road trip - four hours there & four hours back! However, since we were on this epic journey, I decided it was worth the detour - just to say we did it!
The Four Corners Monument is where the states of Colorado, New Mexico, Arizona & Utah all meet in one spot. There is a marker there where you can stand on all 4 states simultaneously.
The monument is out there. I mean, it is way out there! There is literally nothing around. I think the closest lodging is even 45 miles away. It is smack in the middle of the desert so it is hellish hot in the summer. the plaque is metal, so everyone was burning themselves trying to do the "Twister Move" - one limb in each state - for photo ops.
The monument lies on Navajo land. As such, there are lots of vendors selling handmade Navajo wares on site. They are reasonably priced & nice quality.
If you decide to go, just know that you will make this pilgrimage for what quite literally takes no more than 10 minutes to see. However, it really is a fun thing to say you did!
