Observations and Notes

May 4, 2014 Visit to Site

Of all the arrows we visited, this was our favorite.  Just to reach the base of the path to the arrow, we had to drive approximately five miles on a dirt/gravel road, part of which was ‘washboard’.  The last ½ mile we had to use 4-wheel drive, due to the road being uphill on loose shale.  The hike up the hill itself must be done slowly and with caution due to the loose shale.

Silver Zone Pass is completely intact 90° arrow.  The view from the top of the mountain was incredible, as the air was completely clean.  I could see for miles.  It was late afternoon when I reached it, which just enhanced the colors and shadows.  In the very far distance I could barely make out I-80.  The first two parts of the arrow (five-part arrow) were located on an uphill slope.  The middle portion of the arrow (where the beacon stood) was on level ground, while the next two portions (the arrow itself) were on a downhill slope.  A small portion of each of the beacon tower legs still remain imbedded in the arrow.

The pilot would approach the tail of the arrow on a compass heading of 70° (E-NE), and then exit the arrow on a compass heading of 160° (S-SE).
(All measurements and compass headings are approximate).

National Geodetic Survey Datasheet LQ0620

Described by coast and geodetic survey 1940 (JCS)  station is located about 20 miles, airline, NW of Wendover, 11.4 miles se of oasis, 1.5 miles ne of U.S. Highway 40, on the  highest point of a steep, comparatively low hill, on the Toano  range of mountains. The hill appears as a prominent knob from the easterly or westerly directions, although it sets in the saddle of the range. The saddle is known as Silver Zone Summit.

The beacon is a standard, red-and-white, striped, rotating  airway beacon about 75 feet in height, with a concrete arrow at its base, which indicates a right-angle turn in the air lane by right-angle crook in the shank of the arrow. The supply-and-control house along with a dwelling and accompanying sheds, are 600 feet SW, at the foot of the hill the beacon is on.

Station recovery (1957)
