6	6	1906	1630-1830 CST	Burr Oak, IA to Stoddard, WI to Coon Valley 10NE	Fillmore (MN), Houston (MN), La Crosse (WI), Vernon (WI), Winneshiek (IA)	55	400	4	18	F4
			"The tornado was flrst observed in northeastern Iowa at 430 pm, near Burr Oak. Passing east-northeast near Reno, MN, and Stoddard, WI where it crossed the Mississippi River at 5:40 pm. It was last observed at 6:30 pm in the town of Washington, La Crosse County, WI, about 2 miles west of Portland. Its path curved slightly to the northward as it progressed, and was about 55 miles in length. It destroyed all buildings in its path, killed 4 persons and injured 18. A mother and two children were killed as their farm near Freeburg, MN was leveled. One child was carried about half a mile. The other death occurred 2 miles east of Stoddard. The property loss was estimated at $70,000, exclusive of timber and crops, but the latter were not damaged to any great extent, because they were not far advanced. The tornado was characterized by many peculiar and violent phenomena usual to these storms. There was comparatively little electrical display, nor was the rainfall unusual. Its crossing the river near Stoddard was marked by well defined waterspout formation, and it destroyed a heavy wooden railway bridge across the Raccoon Creek nearby. Its action on the steep bluffs and in the deep ravines that mark the banks of the river was peculiar in that the windward or southwest exposures suffered far less damage, as shown by prostrated timber, than did the northeast slopes, where the full vorticular effect was very evident; whereas the southwest slopes, instead of showiug trees thrown in all directions, as is usual, showed trees, with few exceptions, thrown to the left across the entire breadth of the track. Many of the trees on these southwest slopes were broken off 10 to 15 feet above the ground. Another peculiar feature was the decreased violence on the top of the bluffs, which are here about 400 feet above the valley, and the immediate resumption of full destructive effect, not only in the deep ravines, but on the lee side of steepest declivities. Such destruction as occurred on the tops of steep hills crossed by the storm was most apparent on the farther edge, where trees invarlably were thrown in the direction of the storm, probably caused by the air rushing toward the vortex when it had resumed full violence at lower levels. The path of the storm averaged about 400 yards wide where its action could be determined in the timber. The vortex was quite distinct and regular, and, compared with the height of the bluffs which it crossed, seemed about 800 feet high, rapidly widening at the top. The vorticular motion was plainly discernible. Hail fell on the northwest side of the track. It took something less than 2 hours to travel its course."
