Keep in mind that I don’t even know if they have an interesting or unusual postmark. I’m just keen on the idea of a little post office in a very unique location.
Non-US Postcrossers need a US Global Forever stamp on the postcard that they want postmarked and returned. (You can also use a combination of US Forever stamps to equal the global postage ($1.30 now), but putting that many stamps on will obscure the postmark.)

Are you familiar with the post office located at the bottom of the Grand Canyon that services the Havasupai Indian Reservation? It’s the only mail route that uses mules.
This sounds interesting, are you writing on the postcard you want sent back and then mailing in an envelope? Why does it require a global stamp, and is that both ways?
They likely don’t have a unique postmark but if it anything like the rest of the other offices for sure it will be round with the city state zip and the date as well as the letters USPS. Let us know how it looks when it arrives.
There is a forum thread about “unique” post offices, and there was a recent Postcrossing blog post about the Black Pyramid Post Box (but not a post office.) And in a related note, there’s a post office atop Mount Fuji.
There is an underwater post office and a post office located on a slope of an active volcano
Both offices are in Vanuatu (island nation in the Pacific)
Letters & cards sent via these offices receive special cancellation
Russia’s northernmost post office is located on Hooker island in the Arctic. The office is open only during summer months, it is a popular tourist destinations for cruise-ship passengers in the Arctic.
Tourists can send postcards from the island. All cards receive special cancellation.
Yup. I climbed for hours to get to that post office. They are open only for several weeks during summer. Postal workers take turns to stay on the mountain for 1 or 2 weeks. I heard they use a vehicle (bulldozer?) to bring mail down every weekday. My postcards were delivered in a few days.
They did not open the post office in 2021 due to COVID
This is Japan’s Showa Station Post office in Antarctica.
I was going to add the post office in Amboy California. I took a motorcycle road trip to Las Vegas many years ago and visited this outpost on Route 66, located in the desert quite literally in the middle of nowhere. Unfortunately it is no longer listed on the USPS website, so it looks like it has been closed.
Bangalore, India: Larsen & Toubro is implementing a project in Bangalore to construct India’s first post office using 3D printing technology. The building, which will cost 30-40% less than conventional buildings, is expected to be completed within a month, with the basic structure expected to be completed in 15 days. The project is expected to help reduce construction costs for post offices and may encourage low-cost housing projects in the future.
