News Account:
On Sunday, March 1, began the greatest snowstorm of the season, and the severest in many respects known in the west for years. The storm extended from beyond the Missouri River in a belt ranging from the south half of Dakota to Kansas, eastwardly over the states of Nebraska, Kansas, Missouri, Iowa, Minnesota, Wisconsin, Illinois, Indiana, Ohio, Michigan, the Canadas, Western Pennsylvania, New York, and the New England states. South of the line of forty-one degrees this storm was accompanied by rain, and in some places by a slight sprinkle of snow. North of that line there was no rain, but a fall of snow almost unprecedented at any time but never equaled as late in the season as March. The depth of snow rendered more obstructive to travelling because of its drifting, and its close massing under the force of a most furious wind, extended as far eastward north of the line of the Pittsburgh and Fort Wayne railway, as New England.
