This is not express delivery. In an age of one-hour delivery and overnight shipping, a corner of the country still gets its mail by mule.

These hooved carriers trek three hours down (and five hours up!) the Grand Canyon to deliver the mail to a small group of people in a remote region only accessible by foot, raft or helicopter—and they do it six day a week. 

What gets delivered? Mostly food, but also medicine and small appliances. See if you can spot the Amazon Prime boxes. 

The last official mule route isn’t the only thing connecting the National Parks and the mail, as we learned through our National Postal Museum.

Happy 100th Birthday to the National Park Service! Today in 1916 President Woodrow Wilson signed into law the Organic Act which created the NPS and paved the way for the protection of our most beautiful, rugged, and historic places. Thank you to all those involved with the NPS that work to keeping our parks pristine.

Admission to all NPS units is free from August 25th to August 28th in celebration of the Centennial, so get out there and enjoy one near you. If you’d like to know more about how you can participate in the Centennial, then head over to
