The briny pond is but a wee thing as compared with its gigantic dimensions in the days when its waters were sweet and had an outlet to the north. Then its arms spread far south into Arizona, over into Nevada and into Idaho. It was 350 miles from the northern end to the southern, and 145 miles across from east to west. The area was 20,000 square miles. This greater lake stood 1,000 feet higher than does the present one, although this one is 4,280 feet above the level of the sea. Geologists have named the earlier one Bonneville, in honor of the intrepid soldier-explorer whom Washington Irving has so well fixed in American literature. By some as yet unknown cataclysm a great break was made at the north end of this inland ocean and its pent volume was poured into the cañon of the Port Neuf toward the ravenous Snake. This reduced the level four hundred feet, but the old beach line may still be easily noted. Gradually this diminished body became smaller and smaller until it reached the present stage of desiccation. So impure is this heavy liquid that after evaporation there is a residuum of twenty-eight pounds of solid matter in every hundred. This is composed of salt, magnesium, and other elements carrying three dollars of gold to the ton; the gold is not made a matter of trade or of industry because facilities are lacking for its handling. Very little animal life is found in this brine, and none of vegetable; in fact, at every point where the water touches the shore vegetation vanishes utterly. The animal life is that of a very small gnat which, mosquito-like, lays its eggs on the surface of the water. The larvæ, when driven shoreward, collect in such quantities as to cause a strong, unpleasant odor observable for miles to the leeward. Myriads of seagulls here find a dainty feast. Salt Lake affords the finest and really the only beach-bathing resort in the whole interocean country. The bathing is attended with little, if any, danger. In thirty years only two persons have been lost. These strangled before assistance reached them. One body was found after four years, lying in the salty sand at the south end of the lake, whither the high winds from the north had drifted it. All the parts protected by the sand were perfectly preserved and as beautiful as if carved from Parian marble. The tops of a number of sunken mountains still protrude above the surface and form islands: such are Fremont, Church, Stanbury, Carrington, and others. Some of these are habitable, possessing fine springs and irrigable land. Very few people live on these islands, but some brave spirits dare to face the semiprivations of such isolation and stay there with their herds.
