Step 1 : Introduction to the question "How is mail delivered to residents and businesses in the Grand Canyon?"
...There are only two places in the United States where mail is still delivered by mule, and both — Phantom Ranch and Supai Village — are located within the Grand Canyon. With no roads reaching the canyon floor, standard postal trucks simply cannot operate there. Instead, mule trains carry letters, packages, food, and essential supplies along steep, winding trails carved into the canyon’s rugged terrain. This time-honored system, in continuous use for more than a century, remains one of the most distinctive and logistically challenging mail routes in the United States.
