Inscription.
Latitude 4046'04" - Longitude 11154'00"
Altitude (sidewalk) 4327.27 Ft.

Fixed by Orson Pratt assisted by Henry G. Sherwood, August 3, 1847, when beginning the original survey of “Great Salt Lake City,” around the “Mormon” Temple site designated by Brigham Young July 23, 1847. The city streets were named and numbered from this point.

David H. Burr, first U.S. Surveyor-General of Utah, located here in August 1855, the initial point of public land surveys in Utah, and set the stone monument, still preserved in position.

An astronomical station, its stone base still standing 100 ft. N. and 50 ft. W. of this corner was established by George W. Dean, U.S.C.&G. survey, September 30, 1869, to determine the true latitude and longitude; it was used to obtain correct time at this point until December 30, 1897.

This is the intersection that is the base point for the address numbering system for Salt Lake City and the surrounding area. Four historical markers are visible in the photo. At the far left is the bust of Charles Savage on top of the Honor Thy Father and Mother marker. Immediately to the right of that is the Great Salt Lake Base and Meridian. At the center is the Brigham Young Monument and at the far right the marker for the Hotel Utah is just barely visible about three feet off the ground next to the corner of the building.
. Marker is at the intersection of South Temple Street and Main Street, on the right when traveling west on South Temple Street. Click for map. Marker is in this post office area: Salt Lake City UT 84116, United States of America.

More about this marker. There is a noticeable discrepancy between the coordinates given on the marker and those given by GPS. If you go to the location given on the marker using a GPS, you end up at about 70 S. 300 West. This is probably due to GPS systems using a different Datum than that used for the Marker.

Additional comments.
1. Different Coordinates for the Marker
The Meridian Project (http://www.pmproject.org/) used Google/Earth and GPS units to determine additional ccordinates for many of the principal meridian markers. Their findings match very closely the coordinates given by GPS receivers at the site which differ by about 1/2 mile in west longitude from the marker itself.
