Work on the excavation began immediately; on the afternoon of the very day of dedication, plows and scrapers were put in action. As announced at the time of the dedication of the site, the following specifications as to dimensions and construction had been decided upon:
"Outside measurement, 142 feet long by 96 feet wide, including the buttresses, and 80 feet high to the top of the parapet. It will be built of stone, plastered outside and inside. There will be a tower in the center of the east end, and on the extreme corners of the same end, right and left of the tower, are cylindrical staircases; one side of the stairs rests in the cylinder, the other side in a newel in the center of the cylinder. The roof will be flat, and covered with roofing similar to that on the New Tabernacle in Salt Lake City. The building will consist of two stories and a basement. The two main rooms or halls, one over the other, will each be 100 feet by 80 feet. The ceiling of these will be arched, resting upon columns, and so constructed as to admit of sixteen rooms for council and other purposes in each of those two main stories. The height of the main ceiling in the centre is 27 feet; the height of the other ceilings about 9 feet. The basement will contain the font, and will be used for ceremonial purposes."[[1]]
A record-stone was placed at the south-east corner of the building, and therein were deposited, on March 31, 1873, a metallic box containing copies of the scriptures and other publications of the Church, together with a silver plate bearing the following inscription:
"Holiness to the Lord.
"The Church of Jesus Christ of Latter-day Saints was organized and established agreeable to the laws of our country, by the will and commandments of God, on the sixth of April, 1830. Which commandments were given to Joseph Smith, Jr., who was called of God, and ordained an Apostle of Jesus Christ, to be the first Elder in the Church.
"Joseph Smith, Jr., President, with his brother Hyrum, Patriarch of the whole Church, suffered martyrdom in Carthage, Illinois, June 27th, 1844, and the Church was driven into the wilderness in 1846."
Then followed the names of all the general authorities of the Church as at that time constituted.[[2]]
To the specifications given in the foregoing it is necessary to add only the following to make the description fairly complete. The tower is thirty-one feet square; the vane on the tower is one hundred and seventy-five feet from the ground. The foundation of the entire basement story consists of a black basaltic lava, a rock occurring abundantly in the region and well adapted to the purpose. The soil of the place is sandy and heavily impregnated with alkaline mineral salts; and no rock that readily undergoes disintegration, either through abrasion or as the result of a solution of cementing material, is suitable for foundation work in this soil. The foundation of the building extends below the ground-level ten feet. About two-thirds of the east end and a portion of the northerly side rest on bed-rock in place; throughout the rest of its extent the foundation is laid on a thick layer of broken volcanic rock firmly compacted under the blows of a nine-hundred-pound pile driver. A capacious drain encircles the building and connects with a yet larger drain fifty feet easterly from the square tower. The foundation is twelve feet wide at the bottom, and the walls are gradually diminished in width so that at the level of the basement window sills they have a thickness of three feet eight inches. Above the basement story the building is constructed of the fine red sandstone of the region, from quarries specifically located and opened for this work. Timber and lumber had to be hauled by team from distances of from seventy to ninety miles.
The Temple stands in the open plain on but a slight elevation, practically devoid of all the prominence that belongs to a commanding position of altitude. The ground on which the building rests, as well as the region for miles round about, is of a prevailing dark-red color; and this, too, is the color of the sandstone of which the Temple is built. Naturally, the building as a whole would blend with its surroundings, so as to be practically invisible from even a moderate distance. A contrast has been afforded by whitening the walls; and as a result the structure has become a striking feature of the landscape.
As to the interior it may be sufficient to say that all the ordinance work connected with baptism, ordination, endowment, and sealing, as performed in the Temple at Salt Lake City, is administered in a similar manner in this Temple, and provision therefor is made. For all the sacred ordinances there is ample equipment of rooms and furnishings. The basement floor is divided into fourteen rooms of which the baptistry or font-room, thirty-five by forty feet, is one of the largest and most important. As is usual, the baptistry is situated below the general level of the assembly rooms. Also as in the other temples, the baptismal font rests upon twelve oxen of cast iron, which occupy a depression slightly below the floor. The font, oxen, iron stairs, and all accessories, weighing in all over eighteen thousand pounds, were cast in Salt Lake City and were hauled by team thence to St. George. The entire baptistry equipment was the personal gift of President Brigham Young.
Above the basement there are two stories. In each of these there is one main room ninety-nine by seventy-eight feet inside measurement, with an arched or elliptical ceiling twenty-seven feet from the floor in the center. Flanking this main apartment on either side are a number of smaller rooms used for ordinance work and as assembly rooms for councils of the Priesthood. The large room on the middle floor corresponds in use to the splendid Celestial Room already described as a prominent feature of the Temple at Salt Lake City. In the same way the large room on the upper floor corresponds to the main assembly room on the fourth floor of the Salt Lake City Temple, and is provided with pulpits at both east and west ends, the former devoted to the use of the Higher or Melchisedek Priesthood, the latter reserved for the officials of the Lesser or Aaronic order of Priesthood.
Adjoining the main building is an accessory structure known as the Annex; this is seventy-four feet long by twenty-four feet wide, exclusive of a "lean-to" on the east side, which is forty-three feet by nine feet. The Annex was built in 1882. It contains boiler and engine rooms, apartments for the guard, a refectory for the accommodation of workers, recorder's offices, etc.
