On my way to Zion NP, I visited several airmail navigation arrow sites in the St. George area of southern Utah. This one is located in a suburban neighborhood on a bluff above an area called Bloomington. The Arrows Across America web site reports that this arrow site is number 37A along the Los Angeles to Salt Lake City route.
Here's a Google map centered on the arrow. It's easy to drive to this arrow and I don't even need to describe my route. The arrow is located next to a water supply tank in the green circle on the image below.
This arrow site includes a monument plaque attesting to Utah's role in aviation history.
This arrow points toward another arrow atop a slanted butte named Shinob Kibe on the east side of St. George in a city named Washington.
Here's a view to the north.
And a view to the SE. The Walmart store is visible below.
