St. Croix county, as at present constituted, lies on the east bank of the river and Lake St. Croix, forming, but for slight irregularities on the western line, a parallelogram. It includes townships 28 to 31, and ranges 15 to 19, with fractions of range 20 on the west. The surface varies from gently undulating to hilly. The bluffs along the lake are not precipitous, as on the Upper St. Croix, but are even and continuous, with gently rounded slopes. From the river, eastward, the country is broken and somewhat hilly; the central portions are rolling prairies on which are fine farms, and the eastern portions are level and originally heavily timbered. The eastern tier of townships is covered by a heavy growth of timber known as the Big Woods. The timber is composed of basswood, maple, butternut, several species of oak, and a sprinkling of white pine. The soil is a rich clayey loam and well adapted for grass, grain and root crops. Good building and limestone crop out in places. The county is well drained by the St. Croix and its tributaries, Apple, Willow and Kinnikinic on the west and Rush river on the east. Of these tributaries Apple river is the largest. It rises in Polk county, where it is supplied by numerous lakes, enters St. Croix county and passes diagonally across the northwest corner and empties into the St. Croix river a few miles above Stillwater. Willow river rises in Cylon township and empties into St. Croix lake, just above Hudson. This river passes through a deep gorge in the limestone rock, a few miles above its mouth, falling in its passage over several ledges of rock, producing falls famed far and near for their wildness and grandeur. Kinnikinic river in the south part of the county is famed also for the beauty of its scenery and for its waterfalls. It passes into Pierce county and then, uniting with its southern branch, flows into Lake St. Croix. Rush river rises in Eau Galle, and turns and flows thence to Lake Pepin. These streams have unfailing supplies from springs and small lakes. There is a remarkable formation in the Kinnikinic valley about seven miles above River Falls, called the Monument. It is a ledge of pure white sandstone rock, nearly circular, and rising to a height of sixty feet. It stands on a natural elevation far above the level of the valley and so forms a very conspicuous and curious object. The base is forty or fifty feet wide, and the summit is a turret-shaped mass of rock about fifteen feet wide and as many high. The part upon which the turret rests is dome-shaped, its sides worn by the rains into deep furrows. Years ago a tree grew upon the summit. The soft sandstone is being gradually worn away by the winds and rains. HOW THE SCHOOL LANDS WERE SELECTED.
