Bedrock geology at the south-central part of the North Range, Cuyuna district, Minnesota

The Cuyuna iron-ore district is in central Minnesota in Morrison, Crow Wing, and Aitkin Counties. The length of the district is about 68 miles, extending from near Randall in Morrison County ot a point 11 miles east of the community of Hassmann in Aitkin County, and the maximum know width is about 25 miles near the center of the district. Current mining activity is confined to a much smaller area about 10 miles longs and 3 miles wide near Crosby and Ironton in Crow Wing County. This investigation has been restricted to the active area plus a marginal strip in which much exploratory drilling has been done. The average annual production of iron ore and manganiferous iron ore from the district during 1940-50 was slightly more than 3 million tons.

Report on the geology of the high plateaus of Utah

In the year 1874 my kind friend Prof. J.W. Powell proposed to me that I should undertake, under his direction, the study of a large volcanic tract in the Territory of Utah, provided the consent of proper authority could be entertained. Distrusting my own fitness for the work, I felt that it would be better for him if his proposals were thankfully declined. In 1875, however, he renewed the proposition in such a friendly and complimentary manner that a refusal seemed ungracious. He therefore laid the matter before the Secretary of War, the General of the Army, and the Chief of Ordnance, all of whom gave their cordial approbation; and by order of the Ward Department I was detailed for duty in connection with the survey of the Rocky Mountain Region in charge of Professor Powell. The field which he assigned me to study was the District of the High Plateaus, and the investigations were made during the summers of 1875, 1876, and 1877. The preparation of a report or monograph upon the district has several times between interrupted by the pressure of other official duties to which the writer has been assigned during the last three years.
