Observations and Notes

Upon leaving Mormon Mesa Arrow #32, we then continued southbound on I-15 for 14.5 miles and pulled into another ‘truck pull-out’ alongside the freeway.  The gravel road to the arrow begins at the pullout itself.  There was a closed gate (unlocked) at the beginning of the gravel road, but there were no signs posted saying ‘Keep Out’.  We just made sure that the gate was secured after we went thru.  The gravel road runs south (parallel to the freeway) all the way out to the arrow.

The arrow is in good condition and almost completely intact.  The only part missing was the base where the generator shed once stood.  This arrow was unique, as it was a ‘step-arrow’. 

The remaining portion of the arrow is 44 feet in length.

The pilot would approach the tail of the arrow on a compass heading of 48° (NE), and then exit the arrow on a compass heading of 68° (E-NE).
(All measurements and compass headings are approximate).
